Cryptography basics: What is Encryption and Decryption
Get Full Course: http://www.engineeringmentor.com/CNYTv3 Networks #3: This tutorial introduces the Cryptography basics. It also explains what is Encryption and Decryption. a) Cryptography basics (00:21):http://youtu.be/BEb_AnPWPwY?t=21s how do we provide this security during transmission? Well, One way of ensuring security can be use of CRYPTOGRAPHY! Cryptography is a field of network security which deals with hiding "real" infromation when it is under transmission between the two parties. Usually, the real information is transformed or hidden into another message and transmitted over the network. This transformed message in itself will make no sense even if any hacker gets hold of this information. When it reaches the destination, the receipent will know a method to de-transform the garbage message into the original information which the sender had sent.method of transforming message at sender's side and de transforming at reciever's side forms the basic model of Cryptography. b) Encryption and Decryption (3:57):http://youtu.be/BEb_AnPWPwY?t=3m57s First, the information to be transmitted, called as plain text(or message) is fed to an Encryption system. The Encyrption system uses a key to convert the plain text to encyrpted form which looks like garbage value. This is also called as cipher text. A corresponding key is used at the other end to decrypt the cipher text back to original message. When we say a key, it actually means a piece of string value which is fed to encyprtion and decryption algorithms along with the text for transformation. When the message reaches the destination, this system at the other end decrypts the cipher text into original message with the help of the key. This is called as Decryption System. The output of the Decryption System is the intended message. Depending on how the keys are shared, we can classify crytography as symmetric and asymmetric. If the keys used by both parties are same, then it is called symmetric key cryptography, or private key cryptography. If both parties use different keys for encyrption and decryption, then it is called asymmetric key cryptography or public key cryptography. video URL : https://www.youtube.com/watch?v=BEb_AnPWPwY Watch ALL CN VIDEOS: https://www.youtube.com/playlist?list=PL9OIoIp8YySF4mkIihOb_j2HZIRIlYuEx For more, visit http://www.EngineeringMentor.com Facebook: https://www.facebook.com/EngineeringMentor Twitter : https://twitter.com/Engi_Mentor

Public Key Cryptosystems: Stronger Security from General Assumptions
Public key encryption (PKE) allows parties that had never met in advance to communicate over an unsafe channel. The notion was conceived in the 1970s, followed by the discovery that one could provide formal definitions of security for this and other cryptographic problems, and that such definitions were achievable by assuming the hardness of some computational problem (e.g., factoring large numbers). For PKE, the most basic security definition -- semantic security -- guarantees privacy, namely that it is infeasible to learn anything about the plaintext from its encryption. However, as cryptographic applications grew more sophisticated, this level of security is often not sufficient, since it does not protect against active attacks arising in networked environments. In this talk I will review some of my work aimed at achieving stronger security notions for public key encryption, including protections against adaptive corruptions, man-in-the-middle attacks (non-malleability), chosen ciphertext security, and, if time allows, tampering attacks. The emphasis of this line of work is on achieving the stronger notion from as general an assumption as possible (e.g., directly from semantically secure PKE), as well as achieving a black box construction, namely using the underlying scheme as a subroutine, without assuming it has any special structure or algebraic properties. This allows for more efficient cryptosystems that can be instantiated with a larger set of assumptions. Based on several joint works with different coauthors. The main part of the talk will be based on joint works with Seung Geol Choi, Dana Dachman-Soled, and Hoeteck Wee.

VHDL Implementation of Lossless and Reversible Data Hiding in Encrypted Images with Public Key

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 This paper proposes a lossless, a reversible, and a combined data hiding schemes for ciphertext images encrypted by public key cryptosystems with probabilistic and homomorphic properties. In the lossless scheme, the ciphertext pixels are replaced with new values to embed the additional data into several LSB-planes of ciphertext pixels by multi-layer wet paper coding. Then, the embedded data can be directly extracted from the encrypted domain, and the data embedding operation does not affect the decryption of original plaintext image. In the reversible scheme, a preprocessing is employed to shrink the image histogram before image encryption, so that the modification on encrypted images for data embedding will not cause any pixel oversaturation in plaintext domain. Although a slight distortion is introduced, the embedded data can be extracted and the original image can be recovered from the directly decrypted image. Due to the compatibility between the lossless and reversible schemes, the data embedding operations in the two manners can be simultaneously performed in an encrypted image. With the combined technique, a receiver may extract a part of embedded data before decryption, and extract another part of embedded data and recover the original plaintext image after decryption.

Lossless and Reversible Data Hiding in Encrypted Images with Public Key Cryptography
Public-key cryptography
Public-key cryptography, also known as asymmetric cryptography, is a class of cryptographic algorithms which require two separate keys, one of which is secret (or private) and one of which is public. Although different, the two parts of this key pair are mathematically linked. The public key is used to encrypt plaintext or to verify a digital signature; whereas the private key is used to decrypt ciphertext or to create a digital signature. The term "asymmetric" stems from the use of different keys to perform these opposite functions, each the inverse of the other -- as contrasted with conventional ("symmetric") cryptography which relies on the same key to perform both. Public-key algorithms are based on mathematical problems which currently admit no efficient solution that are inherent in certain integer factorization, discrete logarithm, and elliptic curve relationships. It is computationally easy for a user to generate their own public and private key-pair and to use them for encryption and decryption. The strength lies in the fact that it is "impossible" (computationally infeasible) for a properly generated private key to be determined from its corresponding public key. Thus the public key may be published without compromising security, whereas the private key must not be revealed to anyone not authorized to read messages or perform digital signatures. Public key algorithms, unlike symmetric key algorithms, do not require a secure initial exchange of one (or more) secret keys between the parties. This video is targeted to blind users.

Guide to Applications of Homomorphic Encryption
Homomorphic encryption is an encryption function which permits encrypted data to be computed without decryption. It is considered as a solution for protecting privacy information in present situations such as cloud computing and machine communication. In this talk, I explain the basic arithmetics under homomorphic encryption: equality and comparison. Then I show how to apply to real world problems: private database query processing and homomorphic computation of (approximate) edit distance for genomic analysis.

Blockchain tutorial 11: Elliptic Curve key pair generation
This is part 11 of the Blockchain tutorial explaining how the generate a public private key using Elliptic Curve. In this video series different topics will be explained which will help you to understand blockchain. Bitcoin released as open source software in 2009 is a cryptocurrency invented by Satoshi Nakamoto (unidentified person or group of persons). After the introduction of Bitcoin many Bitcoin alternatives were created. These alternate cryptocurrencies are called Altcoins (Litecoin, Dodgecoin etc). Bitcoin's underlying technology is called Blockchain. The Blockchain is a distributed decentralized incorruptible database (ledger) that records blocks of digital information. Each block contains a timestamp and a link to a previous block. Soon people realises that there many other use cases where the Blockchain technology can be applied and not just as a cryptocurrency application. New Blockchain platforms were created based on the Blockchain technology, one of which is called Ethereum. Ethereum focuses on running programming code, called smart contracts, on any decentralized application. Using the new Blockchain platforms, Blockchain technology can be used in supply chain management, healthcare, real estate, identity management, voting, internet of things, etcetera, just to name a few. Today there is a growing interest in Blockchain not only in the financial sector but also in other sectors. Explaining how Blockchain works is not easy and for many the Blockchain technology remains an elusive concept. This video series tries to explain Blockchain to a large audience but from the bottom up. Keywords often used in Blockchain conversation will be explained. Each Blockchain video is short and to the point. It is recommended to watch each video sequentially as I may refer to certain Blockchain topics explained earlier.

A Survey on Ring-LWE Cryptography
The Ring Learning-with-Errors problem, proposed by Lyubashevsky, Peikert and Regev in 2010, is a variant of the traditional Learning-with-Errors problem, and is an active research area in lattice based cryptography. It has drawn increased attention due to the important application to constructing homomorphic encryption schemes. The security of RLWE problems relies on the hardness of certain standard problems over ideal lattices. In the first part of the talk, I will review the basics of RLWE problems, the hardness proofs, and major RLWE encryption schemes. Then I will survey different attacks to RLWE, including our new attacks to non-dual RLWE in sub-cyclotomic fields and small error dual RLWE on prime cyclotomic fields. I will end by summarizing the security situation for various RLWE problems. This is joint work with Kristin Lauter and Katherine Stange.

Fully Homomorphic Encryption over the Integers with Shorter Public Keys
At Eurocrypt 2010 van Dijk {\sl et al.} described a fully homomorphic encryption scheme over the integers. The main appeal of this scheme (compared to Gentry's) is its conceptual simplicity. This simplicity comes at the expense of a public key size in ${\cal \tilde O}(\lambda^{10})$ which is too large for any practical system. In this paper we reduce the public key size to ${\cal \tilde O}(\lambda^{7})$ by encrypting with a quadratic form in the public key elements, instead of a linear form. We prove that the scheme remains semantically secure, based on a stronger variant of the approximate-GCD problem, already considered by van Dijk {\sl et al}. We also describe the first implementation of the resulting fully homomorphic scheme. Borrowing some optimizations from the recent Gentry-Halevi implementation of Gentry's scheme, we obtain roughly the same level of efficiency. This shows that fully homomorphic encryption can be implemented using simple arithmetic operations.

Deterministic Encryption: Theory and Applications
The focus of the talk is deterministic public-key encryption schemes. Besides being interesting from theoretical and historical perspectives, the deterministic encryption primitive has applications to fast and secure search on remote data. We study several new notions of security for deterministic encryption and relations among them. We present several very efficient deterministic encryption schemes that provably satisfy the strongest-possible security definition (in the random oracle model). We finally provide the constructions that achieve security for many practical settings, without relying on the idealized random oracle model. The talk is based on joint papers with Mihir Bellare, Serge Fehr and Adam O'Neill.

A Secure Image Steganography Based on RSA Algorithm and Hash LSB Technique
Title: A Secure Image Steganography Based on RSA Algorithm and Hash LSB Technique Domain: Image Processing Key Features: 1. 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. 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. 2. 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. 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. 3. 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.

Fully Homomorphic Encryption; Bi-Deniable Encryption; We Have The Technology, Now Where Next?
Fully Homomorphic Encryption over the Integers Vinod Vaikuntanathan, Microsoft Research We construct a simple fully homomorphic encryption scheme, using only elementary modular arithmetic. The security of our scheme relies on the hardness of the approximate integer greatest common divisors (gcd) problem -- namely, given a list of integers that are 'near-multiples' of a hidden integer, output that hidden integer. Joint work with Marten van Dijk, Craig Gentry, and Shai Halevi. Bi-Deniable Encryption Chris Peikert, Georgia Tech A *deniable* encryption scheme allows a sender and/or receiver, having already performed some encrypted communication, to produce `fake' but legitimate-looking encryption coins and/or decryption keys that make the ciphertext appear as an encryption of some message other than the `true' one. Deniability is a powerful notion for both theory and practice: apart from its inherent utility for resisting coercion, a deniable scheme is also *noncommitting* (an important property for constructing adaptively secure protocols), and secure under selective-opening attacks. To date, however, known constructions have achieved only limited forms of deniability, requiring at least one party to remain uncoerced, and in some cases using an interactive protocol. Our main result is a *bideniable* public-key cryptosystem, i.e., one in which both the sender and receiver can simultaneously equivocate; we stress that the scheme is noninteractive and involves no external parties. The construction is based on the (worst-case) hardness of lattice problems. This is joint work with Adam O'Neill at Georgia Tech. We Have The Technology, Now Where Next? David Molnar, MSR What will it take to convince people that cryptography makes the cloud safe? How might our favourite cryptographic constructions work together with systems moving to the cloud? I will describe examples where existing policies blocked movement of data or computation to the cloud. I will then discuss trends in cloud audit approaches and in document labeling that may be complementary to the use of cloud cryptography. Finally I will talk about what is required today for storing highly sensitive data on premises in a large company.

Steganograhy [Please read description]
Sorry, if you did not understand things about what I talked in video. I made it in a hotchpotch. Well, here are the thingies about what I wanted to discuss in the video. What is Steganography? Steganography is a means of obscuring data where secret messages are hidden inside computer files such as images, sound files, videos and even executable files so that, no one except the sender and the receiver will suspect the existence of stealth information in it. Steganography may also involve the usage of cryptography where the message is first encrypted before it is concealed in another file. Generally, the messages appear to be something else such as an image, sound or video so that the transfer of secret data remains unsuspected. The main advantage of steganography over other methods such as cryptography is that, it will not arose suspicion even if the files fall in the hands of a third party. Unlike cryptographic messages, stegnographic messages will no way attract the attention of a third party by themselves. Thus stegnanography has an upper hand over cryptography as it involves both encryption and obscurity. What are the Applications of Steganography? Steganography is mainly used to obscure confidential information/data during storage or transmission. For example, one can hide a secret message in an audio file and send this to another party via email instead of sending the message in the textual format. The receiver on the other end will decrypt the hidden message using the private decryption key. In a worst case scenario, even if a third party does manage to gain access to the email, all he can find is the audio file and not the hidden data inside it. Other usage of steganography include digital watermarking of images for reasons such as copyright protection. Even though steganography has many useful applications, some may use this technique for illegitimate purposes such as hiding a pornographic content in other large files. Rumors about terrorists using steganography for hiding and communicating their secret information and instructions are also reported. An article claiming that, al-Queda had used steganography to encode messages in images and transported them via e-mails, was reported by New York Times, in October 2001. How do Steganography Tools Work? Stegnography tools implement intelligent algorithms to carefully embed the encrypted text messages or data inside other larger files such as an image, audio, video or an executable file. Some tools will embed the encrypted data at the end of another file so that there will be enough room for storing larger data. There are many steganography tools available online but only a few are able to work flawlessly. I did not find any tool that worked perfectly on both small and large data. However, I have managed to develop my own tool that can work perfectly on all types of files and all size of data. The tool is called “Stego Magic“. You can download it from the following link. Here is the link as discussed in the video :- http://www.gohacking.com/downloads/resources/StegoMagic.zip The zip file contains two versions of Stego Magic: One for encrypting the text messages and the other for encrypting binary files. StegoMagic_TXT can be used to hide text messages in other files such as an image or a sound file. StegoMagic_BIN can be used to hide one binary file in another such as an executable file inside an image or an image inside a video file. With Stego Magic, there is no limitation on the size and type of the file that you are intending to hide. For example, you can hide a video of size 1 GB in an image of size 1 MB or hide an executable file inside a WORD document. The tool is pretty straightforward to use and requires no special understanding of the concept. At the end of the encryption process, a secret decryption key will be generated and the same is required during the decryption process. How to Use Stego Magic? Suppose you want to hide a text message inside a JPG file: 1. Place the JPG and the text file (.txt) in the same folder as that of StegoMagic_TXT.exe 2. Run StegoMagic_TXT.exe and follow the screen instructions to embed the text message inside the JPG image. Also, as discussed in the video, in Windows 7 and Vista you need to run it as administrator. 3. Note down the secret decryption key. Now you can send this image to your friend via email. To decrypt the hidden message, your friend should load this JPG file onto the Stego Magic tool and use the secret decryption key. I hope you’ve now understood what is steganography and how to use it to hide your secret data. For queries and feedback, please pass your comments.

Make your own public private key file encryptor in visual basic.
A visual basic project that makes a file encryptor to send files to your friends that no one but your friend can read. It uses the public private key method. Only a user with a private key can read anything encrypted with his public key. The goal here is to help make it easier to understand how to use public and private keys when encrypting files and the importance of privacy. The method of encryption is technically called asymmetric encryption, but also called public key cryptography. In the video there is also a quick example of how to show attribution properly when using freely available resources. There is an image used available under a creative commons license. The programming code and exe program are available here: h ttps://sites.google.com/site/programmingcodeexamples https://sites.google.com/site/programmingcodeexamples
