The main advantages of both types of ciphers are realized, while most of disadvantages are eliminated. The new approach combines encryption with built-in calculation of the hash for the data integrity, pseudo-random generator, and option for dual shared keys. These properties a re pivotal for ...
More fundamentally, the 64-bit block length shared by DES and most other well-known ciphers opens it up to attacks when large amounts of data are encrypted under the same key. In response to a growing desire to replace DES, NIST announced the Advanced Encryption Stan- dard (AES) program ...
It basically depends on how the http client or server uses the ciphers or other ssl properties during the ssl handshake. Please be aware that this option has some limitations/drawbacks. It might cause other options of a server not to work, so it is advised to test this option in dept. ...
A comparative analysis of several symmetric key ciphers was performed, focusing on handling large datasets. Despite this limitation, comparing different images helped evaluate the techniques' novelty. The results showed that ChaCha20 had the best average time for both encryp-tion and decryption, being...
aBletchley Park, during the Second World War, was the home of the code breakers. It was here that the government code and cipher school worked on decrypting German and other axis’s codes and ciphers, a hugely important job and a very crucial one that helped provide war wing intelligence ...

Summary: We study on the security against higher order differential attack on block ciphers with two-block structure which have provable security against differential and linear cryptanalysis. The two-block structures are classified three types according to the location of round function such as C(...
Advanced Encryption Standard (AES) symmetric ciphers can be optimized to take advantage of Vectorized AES-NI. When used with 512-bit wide registers, one can process up to four AES 128-bit blocks per instruction delivering a significant improvement in bulk encryption throughput in a...

Twofish is a new block cipher with a 128 bit block, and a key length of 128, 192, or 256 bits, which has been submitted as an AES candidate. In this paper, we briefly review the structure of Twofish, and then discuss the key schedule of Twofish, and its
