Abstract. In this paper, we study GF-NLFSR, a Generalized Unbalanced Feistel Network (GUFN) which can be considered as an extension of the outer function FO of the KASUMI block cip...
A vast amount of literature on stream ciphers is directed to the cryptanalysis of LFSR-based filters and combiners, resulting in various attack models such as distinguishing attac...
Hamsi is one of the second round candidates of the SHA-3 competition. In this study, we present non-random differential properties for the compression function of the hash functio...
We propose a novel distinguishing attack on the shrinking generator with known feedback polynomial for the generating LFSR. The attack can e.g. reliably distinguish a shrinking gen...
Square is 8-round SPN structure block cipher and its round function and key schedule have been slightly modified to design building blocks of Rijndael. Key schedule of Square is s...
