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...
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...

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...
This paper describes truncated and impossible differential cryptanalysis of the 128-bit block cipher Camellia, which was proposed by NTT and Mitsubishi Electric Corporation. Our wo...
