We present an AES cipher implementation that is based on the BlockRAM and DSP units embedded within Xilinx’s Virtex-5 FPGAs. An iterative “basic” module outputs a 32 bit col...
In this paper we propose a new cryptanalytic method against block ciphers, which combines both algebraic and statistical techniques. More specifically, we show how to use algebraic...
We show that there is a very straightforward closed algebraic formula for the Rijndael block cipher. This formula is highly structured and far simpler then algebraic formulations o...
Cryptographic hash functions are often built on block ciphers in order to reduce the security of the hash to that of the cipher, and to minimize the hardware size. Proven secure co...
Abstract. We present new related-key attacks on the block ciphers 3WAY, Biham-DES, CAST, DES-X, NewDES, RC2, and TEA. Differential related-key attacks allow both keys and plaintex...
