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...

MISTY1 is a Feistel block cipher that received a great deal of cryptographic attention. Its recursive structure, as well as the added FL layers, have been successful in thwarting v...
We study the differential probability adp of exclusive-or when differences are expressed using addition modulo 2N . This function is important when analysing symmetric primitives t...
In this paper we examine the strength of AES against the related-key impossible differential attack, following the work of Jakimoski and Desmedt [12]. We use several additional obs...
