What is Text Classification ? ----------------------------- Text classification is the process of assigning tags or categories to text according to its content. ... Unstructured data in the form of text is everywhere: emails, chats, web pages, social media, support tickets, survey responses, and more. This projet uses Java 8 and Swing API with following controls JFrame JPanel JDialog JTextField JPasswordField JButton JLable JSeparator Borders EtchedBorder LowerBevelBorder TitleBorder Combobox CheckBox RadioButton Font ImageIcon Image Exception JOptionPane JTable JScrollPane Java: ----- Java is a general-purpose programming language that is class-based, object-oriented, and designed to have as few implementation dependencies as possible. Java is platform Independent language and it is mainly designed for Internet programming, It comes with 3 products mainly Swings API: ----------- Swing is a GUI widget toolkit for Java. It is part of Oracle's Java Foundation Classes – an API for providing a graphical user interface for Java programs. Swing was developed to provide a more sophisticated set of GUI components than the earlier Abstract Window Toolkit. Netbeans IDE: ------------- NetBeans is an integrated development environment (IDE) for Java. NetBeans allows applications to be developed from a set of modular software components called modules. NetBeans runs on Windows, macOS, Linux and Solaris. In addition to Java development, it has extensions for other languages like PHP, C, C++, HTML5, and JavaScript. Applications based on NetBeans, including the NetBeans IDE, can be extended by third party developers. Naive Bayes Algorithm: ---------------------- Naive Bayes classifiers, a family of classifiers that are based on the popular Bayes’ probability theorem, are known for creating simple yet well performing models, especially in the fields of document classification and disease prediction. In this first part of a series, we will take a look at the theory of naive Bayes classifiers and introduce the basic concepts of text classification. Why the name? “Bayes” is named from the famous Bayes’ Theorem in probability, and “Naive” is because the assumptions of this algorithm are very simple and most of the time not true. --------------------Watch My Projects Videos----------------- 1.

More generally, cryptography is about constructing and analyzing protocols that prevent third parties or the public from reading private messages; various aspects in information security such as data confidentiality, data integrity, authentication, and non-repudiation are central to modern cryptography. Modern cryptography exists at the intersection of the disciplines of mathematics, computer science, electrical engineering, communication science, and physics. Applications of cryptography include electronic commerce, chip-based payment cards, digital currencies, computer passwords, and military communications. Cryptography prior to the modern age was effectively synonymous with encryption, the conversion of information from a readable state to apparent nonsense. The originator of an encrypted message shares the decoding technique only with intended recipients to preclude access from adversaries. The cryptography literature often uses the names Alice ("A") for the sender, Bob ("B") for the intended recipient, and Eve ("eavesdropper") for the adversary.[5] Since the development of rotor cipher machines in World War I and the advent of computers in World War II, the methods used to carry out cryptology have become increasingly complex and its application more widespread. AES Algorithm: -------------- The Advanced Encryption Standard, or AES, is a symmetric block cipher chosen by the U.S. government to protect classified information and is implemented in software and hardware throughout the world to encrypt sensitive data. The Advanced Encryption Standard, also known by its original name Rijndael, is a specification for the encryption of electronic data established by the U.S. National Institute of Standards and Technology in 2001 ----------------------Java Cryptography More Videos--------------------------- 1.

Bypassing Local Windows Authentication To Defeat Full Disk Encryption
 
25:57
by Ian Haken In 2007, starting with Windows Vista, Microsoft began shipping a full disk encryption feature named BitLocker with professional and enterprise versions of Windows. Full disk encryption helps protect users from threats that include physical access. This can, for example, prevent the exposure of proprietary information and account credentials if a company laptop is lost, stolen, or even left temporarily accessible to an attacker. Under the hood, BitLocker utilizes a system's Trusted Platform Module (TPM) to store the secret key used for full disk encryption, and is able to use the features of the TPM to safely provide transparent, passwordless decryption of the disk on boot. Because BitLocker can work transparentlywithout any extra passwords or prompts on bootmany enterprises have opted to enable this form of full disk encryption as a part of their data loss prevention strategy. However, in this presentation, I will demonstrate how one can abuse physical access in order to bypass Windows authenticationthus accessing all of a user's dataeven when the disk is fully encrypted by BitLocker. This platform-independent attack effectively bypasses all of the protection offered by BitLocker, reliably and quickly allowing an attacker to retrieve all of the sensitive data on the machine, all without having to perform any cryptographic brute-forcing or hardware manipulation.

Ashwini Oruganti, "Introduction to HTTPS: A Comedy of Errors", PyBay2016
 
29:19
Given recent increases in hostile attacks on internet services and large scale surveillance operations by certain unnamed government organizations, security in our software is becoming ever more important. We'll give you an idea of how modern crypto works in web services and clients, look at some of the common flaws in these crypto implementations, and discuss recent developments in TLS. ​ Abstract In this talk I'll explain what happens behind the scenes when we try to establish a secure connection to a web site. I'll cover the common security flaws in popular TLS implementations like OpenSSL, and show how these issues can be avoided if we have a well-designed TLS implementation in a high level language like Python. Finally, I'll demonstrate and discuss how the API design of OpenSSL leads to application bugs, and a lack of abstract secure defaults leads to insecure applications. Bio Ashwini is a Software Engineer at Eventbrite, and an open source developer living in San Francisco. In the past, she has worked on a pure Python TLS implementation through the Stripe Open Source Retreat, an asynchronous event-driven networking framework - Twisted, and a PHP implementation in RPython called HippyVM. She also served as a Director of the Python Software Foundation last year.

ECC Cryptocurrency Takes Privacy to New Level - Encrypted Messages and File Storage
 
03:04
If you missed out on Bitcoin, ECC may be your second chance. ECC (E- Currency Coin) https://ecc.network/get_ecc ... ECC is a next-generation blockchain cryptocurrency that uses mesh networks (independent side-chains) to achieve network consensus and scalability. Think Ethereum-like confirmation times (less than 1 minute) minus the congestion during high demand ICOs and kitty-trading. Even better, ECC is more than just another digital currency. It’s a multi-layered blockchain that sets up the foundation for many other cool applications, like file storage, messaging and mail. Think ARDR, but instead of multiple tokens, you can transact on network with only one coin and side chains. ECC will have actual utility beyond just coins in a digital wallet and will be easier for the mainstream to adopt than 99% of the cryptocurrencies out there. See, most normies have trouble digesting the idea of digital currencies. Most cryptocurrencies are confusing to your average Joe (See #1 below). So mass/easier adoption = higher demand = higher price. These applications are what will drive the adoption and massive demand, resulting in big gains. These are the specific applications ECC’s team is focused on: 1. Address Name Service (ANS) Right now almost every cryptocurrency wallet address is identified via a public key (ie: 02a1633cafcc01ebfb6d78e39f687a1f0995c62fc95f51ead10a02ee0be551b5dc). This ensures transactions are sent to the correct party, yet they’re hard to memorize or give out to others for receipt of payments (can you imagine typing that on your phone or even on the computer?!). This is a big reason why cryptocurrency is still not “mainstream” yet. Most non-techy people do not understand and are very confused by the concept of public keys and personal wallets, yet most people are very familiar with the idea of “usernames.” ECC solves this public key problem with its ANS (Address Name Service), which maps a chosen “username” to a wallet address. So if your ECC wallet address was 02a1633cafcc01ebfb6d78e39f687a1f0995c62fc95f51ead10a02ee0be551b5dc, you can set up your ANS to be “Jake1990,” and people can send payment directly to “Jake1990.” Similar to how domain names made the internet more accessible to the masses, ECC’s ANS will be easier to use than most other cryptocurrencies. It’s exactly why newbies flock to Coinbase over Gemini (a superior exchange IMO). Because Coinbase is both newbie and user friendly! 2. Decentralized File Storage Currently data storage is centralized within major companies like Google, Amazon or Dropbox. These companies have 100% access to your data and will sell them to data brokers, advertisers, and government agencies (you gave these companies your consent to do so when you signed up, it’s in the terms and conditions).i ECC aims to split files into pieces (encrypted) and save them across various hosts (holders of ECC) to make sure they’re always available and safe. Even if someone does get a hold of your files, it would take a hundred years from them to unencrypt it, if even possible. Anyone can volunteer to become a host by offering up storage space on their computer and get paid in return. Let’s take a look at current blockchain file storage projects and their marketcaps: Siacoin: $1.3 Billion market cap Storj: $207 million market cap Maidsafe coin: $300 million market cap At the time of writing, ECC is under $55 million market cap. It will catch up to Storj within 3-4 months (since its side chains make it more scalable than Storj’s Ethereum based network). That alone would give a solid 4x return. 3.Completely Private Messaging App The third main initial application of ECC is decentralized censorship-resistant messaging. It’s pretty obvious by now that governments are spying on our messages and internet activity. Plus, internet companies are selling our data to advertisers for profit. With the repeal of net neutrality in the US, censorship is about to get worse while privacy will continue to be reduced. Even “secure” messaging apps like Telegram are not completely private because every message is still stored on their servers. (You might be thinking, “I don’t care about governments and big corporations spying on me because I have nothing to hide.” My rebuttal is asking you, “Well would you share all of your emails with the public?” If not then, you do value privacy!) ECC solves this privacy and censorship problem by creating a completely decentralized, encrypted instant messaging app- which later can be applied to email.

Java Projects With Source Code - Honeypot Project in Java

Dear Viewer, thanks for watching this video i will be more happy and pleased if you subscribe my channel and hit like its is my request please do subscribe and hit like and leave comments for further improvements and please give any suggestion for the video i will try to improve it in next video. What is Honeypot ? ------------------ A Honeypot is a program, machine or system, which is used for network security. The basic idea is to deceive the attackers by making the honeypot seem like a legitimate system. It traps attacks, records intrusion information about tools and activities of a hacking process, and prevents attacks outbound the compromised system. We propose a system, which is used for identifying the blackhats’in a network and recording their activities like when they break in and what are their motives. This is done by Data control, Data capture and Data Duplication mechanisms using a honeypot developed in JAVA. We implement these mechanisms to control the intruders and capture their activities without them knowing that they are being under control. This helps in collecting the information about the attacks and the areas of attacks and to make the network security stronger. In computer terminology, a honeypot is a trap set to detect, deflect, or, in some manner, counteract attempts at unauthorized use of information system. Generally, a honeypot consists of a computer, data, or a network site that appears to be part of a network, but is actually isolated and monitored, and which seems to contain information or a resource of value to attackers. This is similar to the police baiting a criminal and then conducting undercover surveillance.

What is DISK ENCRYPTION? What does DISK ENCRYPTION mean? DISK ENCRYPTION meaning & explanation

What is DISK ENCRYPTION? What does DISK ENCRYPTION mean? DISK ENCRYPTION meaning - DISK ENCRYPTION definition - DISC ENCRYPTION explanation. Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license. Disk encryption is a technology which protects information by converting it into unreadable code that cannot be deciphered easily by unauthorized people. Disk encryption uses disk encryption software or hardware to encrypt every bit of data that goes on a disk or disk volume. Disk encryption prevents unauthorized access to data storage. Expressions full disk encryption (FDE) or whole disk encryption often signify that everything on disk is encrypted – including the programs that can encrypt bootable operating system partitions – when part of the disk is necessarily not encrypted. On systems that use a master boot record (MBR), that part of the disk remains non encrypted. Some hardware-based full disk encryption systems can truly encrypt an entire boot disk, including the MBR. Transparent encryption, also known as real-time encryption and on-the-fly encryption (OTFE), is a method used by some disk encryption software. "Transparent" refers to the fact that data is automatically encrypted or decrypted as it is loaded or saved. With transparent encryption, the files are accessible immediately after the key is provided, and the entire volume is typically mounted as if it were a physical drive, making the files just as accessible as any unencrypted ones. No data stored on an encrypted volume can be read (decrypted) without using the correct password/keyfile(s) or correct encryption keys. The entire file system within the volume is encrypted (including file names, folder names, file contents, and other meta-data). To be transparent to the end user, transparent encryption usually requires the use of device drivers to enable the encryption process. Although administrator access rights are normally required to install such drivers, encrypted volumes can typically be used by normal users without these rights . In general, every method in which data is transparently encrypted on write and decrypted on read can be called transparent encryption. Disk encryption does not replace file encryption in all situations. Disk encryption is sometimes used in conjunction with filesystem-level encryption with the intention of providing a more secure implementation. Since disk encryption generally uses the same key for encrypting the whole volume, all data is decryptable when the system runs. However, some disk encryption solutions use multiple keys for encrypting different partitions. If an attacker gains access to the computer at run-time, the attacker has access to all files. Conventional file and folder encryption instead allows different keys for different portions of the disk. Thus an attacker cannot extract information from still-encrypted files and folders. Unlike disk encryption, filesystem-level encryption does not typically encrypt filesystem metadata, such as the directory structure, file names, modification timestamps or sizes. Trusted Platform Module (TPM) is a secure cryptoprocessor embedded in the motherboard that can be used to authenticate a hardware device. Since each TPM chip is unique to a particular device, it is capable of performing platform authentication. It can be used to verify that the system seeking the access is the expected system.

What is OpenCV ? ------------------ OpenCV (Open Source Computer Vision Library) is an open source computer vision and machine learning software library. OpenCV was built to provide a common infrastructure for computer vision applications and to accelerate the use of machine perception in the commercial products. Being a BSD-licensed product, OpenCV makes it easy for businesses to utilize and modify the code. The library has more than 2500 optimized algorithms, which includes a comprehensive set of both classic and state-of-the-art computer vision and machine learning algorithms. These algorithms can be used to detect and recognize faces, identify objects, classify human actions in videos, track camera movements, track moving objects, extract 3D models of objects, produce 3D point clouds from stereo cameras, stitch images together to produce a high resolution image of an entire scene, find similar images from an image database, remove red eyes from images taken using flash, follow eye movements, recognize scenery and establish markers to overlay it with augmented reality, etc. OpenCV has more than 47 thousand people of user community and estimated number of downloads exceeding 18 million. The library is used extensively in companies, research groups and by governmental bodies.

Symmetric Key and Public Key Encryption
 
06:45
Modern day encryption is performed in two different ways. Check out http://YouTube.com/ITFreeTraining or http://itfreetraining.com for more of our always free training videos. Using the same key or using a pair of keys called the public and private keys. This video looks at how these systems work and how they can be used together to perform encryption. Download the PDF handout http://itfreetraining.com/Handouts/Ce... Encryption Types Encryption is the process of scrambling data so it cannot be read without a decryption key. Encryption prevents data being read by a 3rd party if it is intercepted by a 3rd party. The two encryption methods that are used today are symmetric and public key encryption. Symmetric Key Symmetric key encryption uses the same key to encrypt data as decrypt data. This is generally quite fast when compared with public key encryption. In order to protect the data, the key needs to be secured. If a 3rd party was able to gain access to the key, they could decrypt any data that was encrypt with that data. For this reason, a secure channel is required to transfer the key if you need to transfer data between two points. For example, if you encrypted data on a CD and mail it to another party, the key must also be transferred to the second party so that they can decrypt the data. This is often done using e-mail or the telephone. In a lot of cases, sending the data using one method and the key using another method is enough to protect the data as an attacker would need to get both in order to decrypt the data. Public Key Encryption This method of encryption uses two keys. One key is used to encrypt data and the other key is used to decrypt data. The advantage of this is that the public key can be downloaded by anyone. Anyone with the public key can encrypt data that can only be decrypted using a private key. This means the public key does not need to be secured. The private key does need to be keep in a safe place. The advantage of using such a system is the private key is not required by the other party to perform encryption. Since the private key does not need to be transferred to the second party there is no risk of the private key being intercepted by a 3rd party. Public Key encryption is slower when compared with symmetric key so it is not always suitable for every application. The math used is complex but to put it simply it uses the modulus or remainder operator. For example, if you wanted to solve X mod 5 = 2, the possible solutions would be 2, 7, 12 and so on. The private key provides additional information which allows the problem to be solved easily. The math is more complex and uses much larger numbers than this but basically public and private key encryption rely on the modulus operator to work. Combing The Two There are two reasons you want to combine the two. The first is that often communication will be broken into two steps. Key exchange and data exchange. For key exchange, to protect the key used in data exchange it is often encrypted using public key encryption. Although slower than symmetric key encryption, this method ensures the key cannot accessed by a 3rd party while being transferred. Since the key has been transferred using a secure channel, a symmetric key can be used for data exchange. In some cases, data exchange may be done using public key encryption. If this is the case, often the data exchange will be done using a small key size to reduce the processing time. The second reason that both may be used is when a symmetric key is used and the key needs to be provided to multiple users. For example, if you are using encryption file system (EFS) this allows multiple users to access the same file, which includes recovery users. In order to make this possible, multiple copies of the same key are stored in the file and protected from being read by encrypting it with the public key of each user that requires access.

Steganography: Hide Document in Image
 
03:26
This video shows you how to hide a document within an image using a Stenography tool called Xiao. Use your favorite image editor (Gimp, Photoshop, Paint, etc..) and save the image with a .bmp extension. With your favorite text editor (Word, Notepad, etc..) create your document and save it with a .txt extension. Nobody will ever know it is there. You can extract the document when you need to work on it, then re-save it within the image. You can also do this within audio files or video files. I hope this video helped you. Thanks for watching, Have a great day !!

2016 - Marek Śmigielski - Payment card cryptography for java developers
 
50:13
After we've released a first commercial payment card with dynamic cvv code presented on e-ink paper on the bottom of the card there was so much inaccurate comments from the tech people in the social websites that I was scared and at the same time frustrated. People I know, who are the good developers or projects managers simply do not understand the basis of payment cryptographical flows. I was almost screaming that "cvv code is not just random digits! It's cryptographical signature of your card and it is never ever stored or represented on anything except your card and to verify it a super secure hardware called HSM needs to be used to recompute it and decide if the input made by a user in a web browser is the correct one!" Then I've realised that in fact if not for the project I was involved in last year my knowledge would be more or less the same: inaccurate and based on the wrong assumptions. When I looked around for the reasons why there is so much gap between people’s knowledge and real security patterns that are used in payment industry I've found a very simple explanation. There is simply not enough accessible and well presented information about payment cryptography and security measures. There is only highly advanced stuff with more mathematics than text or it is inaccessible due to the necessity of having to be part of payment organisations such as Visa or Security Council. My talk is aiming to fill this gap by introducing the audience to most popular machinery involved in making our world secure enough to trust the credit or debit card. I would like to present: * basis of symmetric cryptography algorithms * key derivation and why it so important for payment protection * how pin flows from ATM to issuer bank in order to be verified * what is HSM and why it is used * one more real world example with online payment transactions * how to tie it all together with PA-DSS certification As a practical bonus I would also like to show some java implementations of those algorithms and contrast it with how integration with the hardware crypto-modules looks like.

What is STEGANOGRAPHY? What does STEGANOGRAPHY mean? STEGANOGRAPHY meaning & explanation

What is STEGANOGRAPHY? What does STEGANOGRAPHY mean? STEGANOGRAPHY meaning - STEGANOGRAPHY pronunciation - STEGANOGRAPHY definition - STEGANOGRAPHY explanation - How to pronounce STEGANOGRAPHY? Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license. Steganography is the practice of concealing a file, message, image, or video within another file, message, image, or video. The word steganography combines the Greek words steganos, meaning "covered, concealed, or protected", and graphein, meaning "writing". The first recorded use of the term was in 1499 by Johannes Trithemius in his Steganographia, a treatise on cryptography and steganography, disguised as a book on magic. Generally, the hidden messages appear to be (or be part of) something else: images, articles, shopping lists, or some other cover text. For example, the hidden message may be in invisible ink between the visible lines of a private letter. Some implementations of steganography that lack a shared secret are forms of security through obscurity, whereas key-dependent steganographic schemes adhere to Kerckhoffs's principle. The advantage of steganography over cryptography alone is that the intended secret message does not attract attention to itself as an object of scrutiny. Plainly visible encrypted messages—no matter how unbreakable—arouse interest, and may in themselves be incriminating in countries where encryption is illegal. Thus, whereas cryptography is the practice of protecting the contents of a message alone, steganography is concerned with concealing the fact that a secret message is being sent, as well as concealing the contents of the message. Steganography includes the concealment of information within computer files. In digital steganography, electronic communications may include steganographic coding inside of a transport layer, such as a document file, image file, program or protocol. Media files are ideal for steganographic transmission because of their large size. For example, a sender might start with an innocuous image file and adjust the color of every 100th pixel to correspond to a letter in the alphabet, a change so subtle that someone not specifically looking for it is unlikely to notice it. Discussions of steganography generally use terminology analogous to (and consistent with) conventional radio and communications technology. However, some terms show up in software specifically, and are easily confused. These are most relevant to digital steganographic systems. The payload is the data covertly communicated. The carrier is the signal, stream, or data file that hides the payload—which differs from the channel (which typically means the type of input, such as a JPEG image). The resulting signal, stream, or data file with the encoded payload is sometimes called the package, stego file, or covert message. The percentage of bytes, samples, or other signal elements modified to encode the payload is called the encoding density, and is typically expressed as a number between 0 and 1. In a set of files, those files considered likely to contain a payload are suspects. A suspect identified through some type of statistical analysis might be referred to as a candidate.

Key Updating for Leakage Resiliency With Application to AES Modes of Operation To get this project in ONLINE or through TRAINING Sessions, Contact:JP INFOTECH, Old No.31, New No.86, 1st Floor, 1st Avenue, Ashok Pillar, Chennai -83. Landmark: Next to Kotak Mahendra Bank. Pondicherry Office: JP INFOTECH, #45, Kamaraj Salai, Thattanchavady, Puducherry -9. Landmark: Next to VVP Nagar Arch. Mobile: (0) 9952649690 , Email: [email protected], web: www.jpinfotech.org Blog: www.jpinfotech.blogspot.com Side-channel analysis (SCA) exploits the information leaked through unintentional outputs (e.g., power consumption) to reveal the secret key of cryptographic modules. The real threat of SCA lies in the ability to mount attacks over small parts of the key and to aggregate information over different encryptions. The threat of SCA can be thwarted by changing the secret key at every run. Indeed, many contributions in the domain of leakage resilient cryptography tried to achieve this goal. However, the proposed solutions were computationally intensive and were not designed to solve the problem of the current cryptographic schemes. In this paper, we propose a generic framework of lightweight key updating that can protect the current cryptographic standards and evaluate the minimum requirements for heuristic SCA-security. Then, we propose a complete solution to protect the implementation of any standard mode of Advanced Encryption Standard. Our solution maintains the same level of SCA-security (and sometimes better) as the state of the art, at a negligible area overhead while doubling the throughput of the best previous work.

Naive Bayes Algorithm: ---------------------- Naive Bayes classifiers, a family of classifiers that are based on the popular Bayes’ probability theorem, are known for creating simple yet well performing models, especially in the fields of document classification and disease prediction. In this first part of a series, we will take a look at the theory of naive Bayes classifiers and introduce the basic concepts of text classification. Why the name? “Bayes” is named from the famous Bayes’ Theorem in probability, and “Naive” is because the assumptions of this algorithm are very simple and most of the time not true. --------------------Watch My Projects Videos----------------- 1.

LokChain Intro Video (2018 v1) MUST WATCH

See, Secure, Develop. LokChain: The only 2048 Bits encryption blockchain built for scaling and interoperability. LokChain platform is a structured web of interconnecting technologies focused on integrating distributed ledger, mobile and IoT as one cryptographically secure ecosystem. Lokchain includes a serverless operating system with both public, private and consortium distributed ledgers using Secret Key Infrastructure (SKI) that’s able to deliver quantum computing immunity for small scale users, enterprises, decentralized applications and internet of things (IoT). Lokchain is developed on the bases of our web of technologies. It taps into NEM (Smart Asset), Hashgraph (Gossip protocol, a-BFT), IoTA (Local consensus) and ECSMID (benevolent Cryptography; 2048 bits encryption derived from AES), and has successfully resolved over 16 problems identified in the current blockchain space. This is a highly profitable inter-blockchain, mobile-to-mobile (Mo2Mo), IoT-to-Mobile (I2M), Mobile-to-IoT (M2I), IoT-to-IoT (I2I), IoT-to-IoT to Cloud security infrastructure which does not rely on any third-party, vendor or server[7]. The assumption is that all these approaches keep their immutable records on blockchain. We feature some of the most advanced technologies in the industry. This qualifies LokChain to the membership of Blockchain 4.0 (4th Generation BCT) family. Lokcoin (LCN), is a native cryptocurrency designed to work seamlessly on LokChain platform, open to cross-over alternative blockchain platforms. LCN is to be issued as proposed on the public NEM mosaic-- Smart asset compliant token. LokChain team will integrate its existing “wallet” function to hold LCN balances and allow users to utilize the tokens on the LokChain platform shortly after the tokens are enacted. The LokChain protocol called Zero Knowledge Proof Triangle Flow (ZT-Flow) is being developed for implementation on its own open source blockchain. We have backed up the token life cycle with a smart hub infrastructure project of $400M+. We are not just building a platform but will engage in staving off cryptocurrency inflation and manipulation with the approach that guarantees market security. This means that the token value will be derived from the amount of money raised against the project cost. When the project is fully completed then we can say that the ecosystem of a smart city is fully converged to maximum profit. It will be a critical point for all contributors. In the current state of art, IoT and blockchain integration is based on public key infrastructure (PKI) cryptography. There is no change in permission and role for users, vendors, mobile nodes and IoT devices. This implies a continuous breach of privacy. On the contrary secret key infrastructure (SKI) used in lokchain emphasizes total data encryption, secure data life cycle (s-DLC), total privacy, perpetual ownership and total autonomy at rest/transient SKI features a clear use of attributes and profiles where each of these holds its own autonomy. Attributes are what you are, what you know and what you have e.g Name, address, imei, driver license, biometrics, etc. SKI changes plain attributes into encrypts. A collection of encrypts represent a Data Nucleus Aggregate (DNA). Sets of 16 or more of these attributes build a profile. A collection of these profiles is called Digital Data Nucleic Authority (DDNA). SKI makes certain that the Confidentiality, Integrity, Availability and Privacy are maintained in a serverless and decentralized blockchain environment. More so, Identity Access Management (IAM) is easier to handle. Majority of the IoT devices can now communicate one-on-one in an intelligent manner by using DNA. This kind of change will attract more participants, reshape market rules and create entirely new business models. LokChain is especially designed for mobile, IoT, businesses and the marketplace. The platform consists of a blockchain based “virtual machine” and defined modules, middleware and software stacks in serverless modes. It supports decentralized processes governed by smart asset residing on the platform’s web-based software and application stacks.

Difference Between Authentication & Authorization | Basic Security Java | Part -1
 
08:50
Follow me on FaceBook: https://www.facebook.com/TechTalkDebu Instagram: next_d_paul LinkedIn : https://www.linkedin.com/in/debu-paul-2817a5121/ and Instagram : tachtalk_debu if you like my video, please subscribe to my channel and share the video This is a Part -1 of Security Tutorial Before jumping into main discussion, let’s make our facts straight about what is authentication and what is authorization. In plain simple English, authentication is the process of ascertaining that “is user really someone who he claims to be“. In technical terms, it’s process of login to system through username/password or any similar mechanisms e.g. finger print scanning, security token, security questions or SAML token received from SSO login. There must be something which can identify the user from others. Once user is inside system, authorization refers to rules that determine “what user is allowed to do”and what he is not e.g. a normal user can post a message in any public group, but users only with editor role will be able to delete something. Authorization is often seen as both the introductory setting up of permissions by a system administrator and the checking of the permission values that have already been set up when a user is getting access to the system. When we secure RESTful web services, we need to take care of both the factors. The two concepts are completely orthogonal and independent, but both are central to security design, and the failure to get either one correct increase the chances of compromised system.. Based on the security level, authentication factor can vary from one of the following: Single-Factor Authentication – It’s the simplest authentication method which commonly relies on a simple password to grant user access to a particular system such as a website or a network. The person can request access to the system using only one of the credentials to verify his identity. The most common example of a single-factor authentication would be login credentials which only require a password against a username. Two-Factor Authentication – As the name suggests, it’s a two-step verification process which not only requires a username and password, but also something only the user knows, to ensure an additional level of security, such as an ATM pin, which only the user knows. Using a username and password along with an additional piece of confidential information makes it virtually impossible for fraudsters to steal valuable data. Multi-Factor Authentication – It’s the most advanced method of authentication which uses two or more levels of security from independent categories of authentication to grant user access to the system. All the factors should be independent of each other to eliminate any vulnerability in the system. Financial organizations, banks, and law enforcement agencies use multiple-factor authentication to safeguard their data and applications from potential threats. For example, when you enter your ATM card into the ATM machine, the machine asks you to enter your pin. After you enter the pin correctly, the bank then confirms your identity that the card really belongs to you and you’re the rightful owner of the card. By validating your ATM card pin, the bank actually verifies your identity, which is called authentication. It merely identifies who you are, nothing else. Authentication : Authentication confirms your identity to grant access to the system. It is the process of validating user credentials to gain user access. It determines whether user is what he claims to be. Authentication usually requires a username and a password. Authentication is the first step of authorization so always comes first. For example, students of a particular university are required to authenticate themselves before accessing the student link of the university’s official website. This is called authentication. Authorization : Authorization determines whether you are authorized to access the resources. It is the process of verifying whether access is allowed or not. It determines what user can and cannot access. Authentication factors required for authorization may vary, depending on the security level. Authorization is done after successful authentication. For example, authorization determines exactly what information the students are authorized to access on the university website after successful authentication. Thanks & Regards, Debu Paul

Block cipher mode of operation
 
20:57
In cryptography, a mode of operation is an algorithm that uses a block cipher to provide an information service such as confidentiality or authenticity. A block cipher by itself is only suitable for the secure cryptographic transformation (encryption or decryption) of one fixed-length group of bits called a block. A mode of operation describes how to repeatedly apply a cipher's single-block operation to securely transform amounts of data larger than a block. Most modes require a unique binary sequence, often called an initialization vector (IV), for each encryption operation. The IV has to be non-repeating and, for some modes, random as well. The initialization vector is used to ensure distinct ciphertexts are produced even when the same plaintext is encrypted multiple times independently with the same key. Block ciphers have one or more block size(s), but during transformation the block size is always fixed. Block cipher modes operate on whole blocks and require that the last part of the data be padded to a full block if it is smaller than the current block size. There are, however, modes that do not require padding because they effectively use a block cipher as a stream cipher. This video is targeted to blind users.

Securing Kubernetes Secrets (Cloud Next '19)
 
42:27
Secrets are a key pillar of Kubernetes’ security model, used internally (e.g. service accounts) and by users (e.g. API keys), but did you know they are stored in plaintext? That’s right, by default all Kubernetes secrets are base64 encoded and stored as plaintext in etcd. Anyone with access to the etcd cluster has access to all your Kubernetes secrets. Thankfully there are better ways. This lecture provides an overview of different techniques for more securely managing secrets in Kubernetes, including secrets encryption, KMS plugins, and tools like HashiCorp Vault. Attendees will learn the trade-offs of each approach to make better decisions on how to secure their Kubernetes clusters.
