Since Rijndael was chosen as the Advanced Encryption Standard, improving upon 7-round attacks on the 128-bit key variant or upon 8-round attacks on the 192/256-bit key variants has...

Abstract. SQUARE, an 8-round substitution-permutation block cipher, is considered as the predecessor of the AES. In this paper, inspired from the recent biclique attack on the AES ...
In this paper we present two related-key attacks on the full AES. For AES-256 we show the first key recovery attack that works for all the keys and has 299.5 time and data complex...
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 ...
Abstract. AES is the most widely used block cipher today, and its security is one of the most important issues in cryptanalysis. After 13 years of analysis, related-key attacks wer...
