Secure Communication
 
04:16
Secure Communication: Public Key Cryptography ------------------------------------------------------------------------------ The internet is a very powerful and useful tool of communication, information, and connectivity. It is very important to keep yourself safe and secure online. There are many ways to be targeted, and this video will teach you how to keep private while communicating on the internet. The best way to secure a message is though encryption. Ciphers and cryptography have been used throughout history to keep data safe from prying eyes. Encryption ----------------- What is encryption? Encryption is the conversion of human readable data, such as a message, to a gibberish called ciphertext. The ciphertext can then only be decoded and read using a certain key or password. In this example, encryption converts "This is really fun!" to a whole bunch of letters and numbers that are unreadable. Examples: Alice and Bob ---------------------------------------- Normal Communication: Lets say that Alice and Bob are best friends who want to stay in touch over the internet. They text each other, send emails, or use a messaging app. This works, but there is no way of knowing who might be listening in. Intercepted Communication: Another person, who we'll call Eve, can intercept any data Alice and Bob send to each other. This is called a man-in-the-middle attack, and allows Eve to read anything transmitted, leaving Alice and Bob with no privacy, and no knowledge that they were overheard. Encrypted Communication: This is where encryption comes in. If Eve can't read the data, it becomes useless to her! Alice encrypts the data, represented here by the lock, then sends the encrypted message to Bob. However, Bob needs the key or password to unlock the encrypted message. Alice can't just send the key, Eve could get it! Alice and Bob also can't meet up in person, the internet is global and they could be anywhere. So how does Alice get the key safely to Bob so he can unlock her message? Public Key Exchange: The solution is public key exchange. Alice and Bob each receive open locks, called public keys. They give these open locks to each other and the world, and keep the key to these locks private. Now if Bob wants to send Alice a message, he encrypts or locks his message using her open lock and sends her the message. She can then open the message using her own matching private key. Use of Public Key Cryptography --------------------------------------------------- That was the basic principles of how public key exchange works. It is used to secure data in many places, including HTTPS in websites, which is the little green lock you may have seen in your browser. Both types of locks are secure. If you want to use public key cryptography yourself, there are many tools available. How to Communicate Securely Yourself With Public Key Cryptography ---------------------------------------------------------------------------------------------------------------- OnlinePGP (http://onlinepgp.ws/) is a website which lets you create your own public and private keys. You enter some basic information, a password, and how secure you want to be. Then you can generate your own key pair. Your public key is your open lock that you can share with everybody. Your private key you use to open messages secured with your lock. Now if you want to send someone a secure message, first write a message, then use their public key, the open lock, to encrypt that message. The encrypted message can now only be read by the person whose public key you used. Copy and paste it and send it to them. To decrypt and read it, they paste the secure message, along with their private key and their own password, and then hit decrypt. You have now successfully communicated securely! Easily Communicate Securely ------------------------------------------------ That was a lot of work to send a secure message. Luckily, there are many great apps which do all of this for you! Telegram is the best secure communication client today. It is on your phone, your computer, and the web. It uses the principles you just learned and gives you the privacy you deserve on the internet. Security Shouldn't Be Hard. ===================================== Clips of Girl with Phone, Person Typing, and Cryptographic Machine from http://www.videvo.net/, and are Creative Commons.

Key Updating for Leakage Resiliency With Application to AES Modes of Operation

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.

LokChain Matrix (2018)
 
00:11
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.

Symmetric encryption
 
02:40
Symmetric encryptionSymmetric encryption algorithms are based on one and the same key used by a sender and a recipient. The information exchange process includes three stages: - a sender sends a key to a recipient; - using this key, the sender encrypts the message and forwards it to the recipient; - the recipient receives the message and decrypts it.A number of factors account for the security level provided by conventional techniques: - Firstly, the encryption algorithm should be reliable enough so that the encrypted message could not be decrypted without the key; - Secondly, the security of the transmitted message should depend on the key only rather than on the algorithm secrecy; - And thirdly, the algorithm should prevent from learning the key even if you know a lot of encrypted/unencrypted pairs.For example, the well-known Caesar cipher is quite easy to decipher, even if you don't know the key. Let me demonstrate you how: - We write a decrypted text; - Then we write the decrypted alphabet under the text; - Then we can read the text going from line to line.However, unlike Caesar cipher, if, instead of a constant shift, we use a variable shift which also changes from message to message, we will get rather a reliable encryption system.This method of encryption is called Vigenère cipher. The shift value is defined by a key word which is usually placed in the beginning of a message. The shift is determined by comparing the key word with the transmitted word. For instance, our key word is LASER. The transmitted word will be as follows:In this event the key will be as follows:Symmetric encryption offers such advantages as high data transmission rate, simple implementation, quite a small key length, and sufficient reliability.Symmetric encryption has one substantial shortcoming. It is useless for authentication as the key is known to both parties.

Facts about Encrypting
 
01:28
Facts about Encrypting There are two basic techniques for encrypting information: symmetric encryption (also called secret key encryption) and asymmetric encryption (also called public key encryption.) PGP is often used for signing, encrypting, and decrypting texts, e-mails, files, directories, and whole disk partitions and to increase the security of e-mail communications. Asymmetric encryption uses two related keys (public and private) for data encryption and decryption, and takes away the security risk of key sharing. Symmetric encryption is the oldest and best-known technique. The RSA algorithm encryption and authentication method is the most commonly used encryption method. This video has been brought to you by JSCAPE LLC. As a leading provider of managed file transfer software and networking solutions to businesses and government agencies in more than 54 countries worldwide, JSCAPE provides secure, seamless and reliable file transfer systems for data delivery that meet a variety of audit and regulatory requirements.

Extracting Speed Spectrum Hidden Data From Digital Media
 
01:24
Title: Extracting Spread-Spectrum Hidden Data from Digital Media Domain: Networking - Steganography Key Features: 1. We consider the problem of extracting blindly data embedded over a wide band in a spectrum (transform) domain of a digital medium (image, audio, video). We develop a novel multicarrier/ signature iterative generalized least-squares (M-IGLS) core procedure to seek unknown data hidden in hosts via multicarrier spread-spectrum embedding. 2. Neither the original host nor the embedding carriers are assumed available. Experimental studies on images show that the developed algorithm can achieve recovery probability of error close to what may be attained with known embedding carriers and host autocorrelation matrix. 3. We propose the information hiding concept to reduce the risk of using cryptographic algorithms alone. Data hiding techniques embed information into another medium making it imperceptible to others, except for those that are meant to receive the hidden information and are aware of it presence. 4. It focuses on methods of hidden data in which cryptographic algorithms are combined with the information hiding techniques to increase the security of transmitted data. We focus our attention on the blind recovery of secret data hidden in medium hosts via multi-carrier/signature direct-sequence spread-spectrum transform domain embedding. MODULE DESCRIPTION Steganography: 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 Digital steganography can hide confidential data (i.e. secret files) very securely by embedding them into some media data called "vessel data." The vessel data is also referred to as "carrier, cover, or dummy data". In Steganography images used for vessel data. The embedding operation in practice is to replace the "complex areas" on the bit planes of the vessel image with the confidential data. The most important aspect of Steganography is that the embedding capacity is very large. For a 'normal' image, roughly 50% of the data might be replaceable with secret data before image degradation becomes apparent. Multi-Carrier Spread Spectrum Embedding: The technique of spread spectrum may allow partly to fulfill the above requirements. Advantages of spread spectrum techniques are widely known: Immunity against multi-path distortion, no need for fiequency planning, high flexibility and variable data rate transmission. The capability of minimising multiple access interference in direct-sequence code- division-multiple-access system is given by the cross-correlation properties of spreading codes. In the case of multi-path propagation the capability of distinguishing one component fiom thers in the composite received signal is offered by the auto-correlation roperties of the spreading codes. Image encryption and watermarking: The host image is an 8-bit or higher grey level image which must ideally be the same size as the plaintext image or else resized accordingly using the same proportions. Pre-conditioning the cipher and the convolution processes are undertaken using a Discrete Fourier Transform (DFT). The output will include negative floating point numbers upon taking the real component of a complex array. The array must be rectified by adding the largest negative value in the output array to the same array before normalization. For color host images, the binary cipher text can be inserted into one or all of the RGB components. The binary plaintext image should have homogeneous margins to minimize the effects of ringing due to 'edge effects' when processing the data using Fourier transform. Image decryption and extraction: (i) The correlation operation should be undertaken using a DFT. (ii) For color images, the data is decomposed into each RGB component and each 1-bit layer is extracted and correlated with the appropriate cipher. (iii) The output obtained in Step 3 has a low dynamic range and therefore requires to be quantized into an 8-bit image based on floating point numbers within the range max (array)-min (array).

Crypto Defenses for Real-World System Threats - Kenn White - Ann Arbor
 
01:36:58
Modern encryption techniques provide several important security properties, well known to most practitioners. Or are they? What are in fact the guarantees of, say, HTTPS TLS cipher suites using authenticated encryption, IPSec vs. SSL VPNs, Property Preserving Encryption, or token vaults? We live in an era of embedded Hardware Security Modules that cost less than $1 in volume, and countless options now exist for encrypting streaming network data, files, volumes, and even entire databases. Let's take a deep dive into the edge of developed practice to discuss real-world threat scenarios to public cloud and IoT data, and look closely at how we can address specific technical risks with our current encryption toolkits. Advanced math not required. Bio: Kenneth White is a security researcher whose work focuses on networks and global systems. He is co-director of the Open Crypto Audit Project (OCAP), currently managing a large-scale audit of OpenSSL on behalf of the Linux Foundation's Core Infrastructure Initiative.

Please give us a THUMBS UP if you like our videos!!! Source:http://en.wikipedia.org/wiki/Ciphertext In cryptography, ciphertext (or cyphertext) is the result of encryption performed on plaintext using an algorithm, called a cipher. Ciphertext is also known as encrypted or encoded information because it contains a form of the original plaintext that is unreadable by a human or computer without the proper cipher to decrypt it. Decryption, the inverse of encryption, is the process of turning ciphertext into readable plaintext. Ciphertext is not to be confused with codetext because the latter is a result of a code, not a cipher.

Secret Image Transmission Fragment-Visible Mosaic Images by Reversible Color Transformations
 
03:10
A New Secure Image Transmission Technique via Secret-Fragment-Visible Mosaic Images by Nearly Reversible Color Transformations A new secure image transmission technique is proposed,which transforms automatically a given large-volume secret image into a so-called secret-fragment-visible mosaic image of the same size. The mosaic image, which looks similar to an arbitrarily selected target image and may be used as a camouflage of the secret image, is yielded by dividing the secret image into fragments and transforming their color characteristics to be those of the corresponding blocks of the target image. Skillful techniques are designed to conduct the color transformation process so that the secret image may be recovered nearly losslessly. A scheme of handling the overflows/underflows in the converted pixels’ color values by recording the color differences in the untransformed color space is also proposed. The information required for recovering the secret image is embedded into the created mosaic image by a lossless data hiding scheme using a key. Good experimental results show the feasibility of the proposed method.
