Key size
Key size In cryptography, key size or key length is the size measured in bits of the key used in a cryptographic algorithm (such as a cipher).An algorithm's key length is distinct from its original cryptographic security, which is a logarithmic measure of the fastest known computational attack on the algorithm, also measured in bits. -Video is targeted to blind users Attribution: Article text available under CC-BY-SA image source in video https://www.youtube.com/watch?v=9VIdgf1rpaM

Triple DES
Triple DES In cryptography, Triple DES (3DES) is the common name for the Triple Data Encryption Algorithm (TDEA or Triple DEA) symmetric-key block cipher, which applies the Data Encryption Standard (DES) cipher algorithm three times to each data block.The original DES cipher's key size of 56 bits was generally sufficient when that algorithm was designed, but the availability of increasing computational power made brute-force attacks feasible. -Video is targeted to blind users Attribution: Article text available under CC-BY-SA image source in video https://www.youtube.com/watch?v=78qOtd4yi74

A Messy State of the Union: Taming the Composite State Machines of TLS
A Messy State of the Union: Taming the Composite State Machines of TLS Karthikeyan Bhargavan Presented at the 2015 IEEE Symposium on Security & Privacy May 18--20, 2015 San Jose, CA http://www.ieee-security.org/TC/SP2015/ ABSTRACT Implementations of the Transport Layer Security (TLS) protocol must handle a variety of protocol versions and extensions, authentication modes, and key exchange methods. Confusingly, each combination may prescribe a different message sequence between the client and the server. We address the problem of designing a robust composite state machine that correctly multiplexes between these different protocol modes. We systematically test popular open-source TLS implementations for state machine bugs and discover several critical security vulnerabilities that have lain hidden in these libraries for years, and have now finally been patched due to our disclosures. Several of these vulnerabilities, including the recently publicized FREAK flaw, enable a network attacker to break into TLS connections between authenticated clients and servers. We argue that state machine bugs stem from incorrect compositions of individually correct state machines. We present the first verified implementation of a composite TLS state machine in C that can be embedded into OpenSSL and accounts for all its supported cipher suites. Our attacks expose the need for the formal verification of core components in cryptographic protocol libraries, our implementation demonstrates that such mechanized proofs are within reach, even for mainstream TLS implementations.
Crypto Defenses for Real-World System Threats - Kenn White - Ann Arbor
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.

TORDES: A new Symetric Key Algorithm
Tordes is a block cipher algorithm (bhushan et al., 2012) .It is unique independent approach which uses several computational steps along with string of operators with randomized delimiter selections by using some suitable mathematical logic. It is specially designed to produce different cipher texts by applying same key on same plain text. It is one of the best performing partial symmetric key algorithms particularly for the text message with limited size in its class.It also protects the cipher text from attacks because it is fully dependent on the key and code cannot be deciphered by applying all possible combinations of keys. The following information invariably used in TORDES For encryption Techniques. 1) Key Values 2) Code sequence string generated from a particular process. 3) Transformation of string. 4) Mirror image of string. This shows that the security of text data is not only depends upon key value. This really increases the security of text file.

VEL TECH MULTI TECH DR.RANGARAJAN DR.SAKUNTHALA ENGINEERING COLLEGE DEPT OF ECE ABSTRACT: We propose a multimedia Encryption based on joint scrambling and compression. Video encryption is known as video scrambling. Multimedia encryption changes the multimedia data stream for secret transmission of video data between client and server. A Video Encryption technique is applied by selecting one out of multiple unitary transforms according to the encryption key generated from random permutation method at the transformation stage. Scrambling is the simplest form of encryption that can be applied to multimedia data. A common theme in real-time image/video processing systems is how to deal with their vast amounts of data and computations. For example, a typical digital video camera capturing VGA resolution, quality, color video (640 × 480) at 30fps outputs 27 million pixels per second. If we consider a gray scale image, each pixel is represented by 8bits and so we need a bandwidth of 216 Mbps to transmit VGA-resolution video. Therefore, video compression is frequently used to decrease the amount of data transmitted over a channel. Discrete Cosine Transform (DCT) is one of the techniques used in compressing video.JPEG image compression standard use DCT (DISCRETE COSINE TRANSFORM). The discrete cosine transform is a fast transform. It is a widely used and robust method for image compression. It has excellent compaction for highly correlated data. DCT has fixed basis images DCT gives good compromise between information packing ability and computational complexity. A.ANITHA(VM5888),D.ILAKIYA(VM6623),M.PRIYADHARSHINI(VM5995)

Cryptography is the practice and study of techniques for secure communication in the presence of third parties . More generally, it is about constructing and analyzing protocols that overcome the influence of adversaries and which are related to various aspects in information security such as data confidentiality, data integrity, authentication, and non-repudiation. Modern cryptography intersects the disciplines of mathematics, computer science, and electrical engineering. Applications of cryptography include ATM cards, computer passwords, and electronic commerce. This video targeted to blind users.

Hackerzvoice NDH2k14 Talks : Renaud LIFCHITZ "A Common weakness in RSA Signatures"
This talk will show a very common weakness in RSA signatures. We will be able to computationally extract public RSA keys from communications and embedded systems in case the public key is voluntarily not published. This weakens RSA signatures where keys of small sizes and/or quality are used and allows direct factoring attacks. 2 studies will be conducted on PGP/GPG e-mails and on the Vigik access control system which protects access to nearly 1 million buildings in France. Bio: Renaud Lifchitz is a French senior IT security consultant. He has a solid penetration testing, training and research background. His main interests are protocol security (authentication, cryptography, protocol security, information leakage, zero-knowledge proof, RFID security) and number theory. He currently mostly works on wireless protocols and was speaker for the following international conferences: CCC 2010 (Germany), Hackito Ergo Sum 2010 & 2012 (France), DeepSec 2012 (Austria), Shakacon 2012 (USA), 8dot8 2013 (Chile)
