What is STEGANOGRAPHY? What does STEGANOGRAPHY mean? STEGANOGRAPHY meaning & explanation
 
06:32
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

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.

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.

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.

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.

Ciphertext
 
07:06
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.

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.

NDC2015 - Is it possible to secure micro-controllers within IoT
 
31:53
With the introduction of micro controllers such as the Arduino, Raspberry Pi and BeagleBone – it has become easy to connect sensors to gather information and utilise network connections to build an IoT ecosystem. Strong encryption schemes like RSA/AES/SHA and ecliptic curves cryptography (ECC) have been difficult to introduce due to limited performance and memory capabilities of the micro controllers used and using standard libraries just isn’t feasible – we find that designated and optimised software is the only feasible way forward. http://ardiri.com/blog/iot_day_oslo_feasibility_of_security_on_micro_controllers

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.

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).

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.
