Security Analysis of Block Cipher KT-64

KT-64: A New Block Cipher Suitable to Efficient FPGA Implementation

This paper proposes a new block cipher called KT-64. We make a cipher using components that are believed secure. The structure of KT-64 is very simple, strong and efficient. We use the controlled substitution-permutation networks (CSPNs) based on controlled elements (CEs) for designing fast block cipher suitable to cheap hardware implementation. Security estimations of KT64 cipher show that pro...

The Security of Cipher Block Chaining

The Cipher Block Chaining { Message Authentication Code (CBC MAC) speciies that a message x = x 1 x m be authenticated among parties who share a secret key a by tagging x with a preex of f (m) a (x) def = f a (f a (f a (f a (x 1)x 2) x m?1)x m) ; where f is some underlying block cipher (eg. f = DES). This method is a pervasively used international and U.S. standard. We provide its rst formal ju...

The Security of the RC6TM Block Cipher

This report presents a preliminary analysis of the security o ered by the RC6 TM block cipher. RC6 is an evolutionary improvement of RC5, designed to meet the requirements of the Advanced Encryption Standard (AES). Our analysis demonstrates that RC6 is highly resistant to di erential and linear cryptanalytic attack, which are currently the two most e ective analytical attacks on block ciphers. ...

Security Analysis of the Full-Round CHESS-64 Cipher Suitable for Pervasive Computing Environments

Wireless networks, telecommunications, and information technologies connected devices in pervasive computing environments require a high speed encryption for providing a high security and a privacy. The CHESS-64 based on various controlled operations is designed for such applications. In this paper, however, we show that CHESS-64 doesn’t have a high security level, more precisely, we present tw...
