SOSEMANUK is a word-oriented stream cipher submitted to the ECRYPT stream cipher project, with a variable-length key between 128 and 256 bits. The algorithm is similar to the strea...
We provide an effective procedure for deciding the existence of off-line guessing attacks on security protocols, for a bounded number of sessions. The procedure consists of a co...
Abstract. Sober-t32 is a candidate stream cipher in the NESSIE competition. Some new attacks are presented in this paper. A Guess and Determine attack is mounted against Sober-t32 ...
Abstract. Camellia and MISTY1 are Feistel block ciphers. In this paper, we observe that, when conducting impossible differential cryptanalysis on Camellia and MISTY1, their round s...
