Recently, medical image encryption has gained special attention due to the nature and sensitivity of data lack effective using innovative techniques. Several schemes have been recommended developed in an attempt improve encryption. The majority these studies rely on conventional However, such improvements come with increased computational complexity slower processing for decryption processes. A...

In order to protect the security of network data, a high speed chip module for encrypting and decrypting of network data packet is designed. The chip module is oriented for internet information security SOC (System on Chip) design. During the design process, AES (Advanced Encryption Standard) and 3DES (Data Encryption Standard) encryption algorithm are adopted to protect the security of network...

This paper details the attack on RC6 which was announced in a report published in the proceedings of the second AES candidate conference (March 1999). Based on an observation on the RC6 statistics, we show how to distinguish RC6 from a random permutation and to recover the secret extended key for a fair number of rounds.

This document contains several sections of the CAST-256 AES Submission Package delivered to NIST on June 9, 1998. All complete submissions received by NIST will be made public in late August at the First AES Candidate Conference, but the following material is being made available now so that public analysis of the CAST-256 algorithm may begin (see, for example, http://www.ii.uib.no/~larsr/aes.h...
