Two new FPGA designs for the Advanced Encryption Standard (AES) are presented. The first is believed to be the fastest, achieving 25 Gbps throughput using a Xilinx Spartan-III (XC3...
Serpent is a 32-round AES block cipher finalist. In this paper we present several attacks on reduced-round variants of Serpent that require less work than exhaustive search. We at...
Abstract. In this paper, we discuss ways to attack various reducedround variants of MARS. We consider cryptanalysis of two reducedround variants of MARS: MARS with the full mixing ...
We present a method for finding efficient instruction sequences for the Serpent S-boxes. Current implementations need many registers to store temporary variables, yet the common ...
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 th...
