Throughput Optimum Architecture of KECCAK Hash Function
International Journal of Computer and Electrical Engineering, 2012 Because of the weakening of the widely-used SHA-1 hash algorithm and concerns over the similarly-structured algorithms of the SHA-2 family; the US NIST has initiated the SHA-3 contest in order to select a suitable drop-in replacement. In this paper we use the unrolling method to describe the high-speed hardware implementation of the SHA-3 hash function

Superposition Attacks on Pseudorandom Schemes Based on Two or Less Permutations
IET Information Security, Volume 2024, Issue 1, 2024.We study quantum superposition attacks against permutation‐based pseudorandom cryptographic schemes. We first extend Kuwakado and Morii’s attack against the Even–Mansour cipher and exhibit key recovery attacks against a large class of pseudorandom schemes based on a single call to an n‐bit permutation, with polynomial O(n) (or O(n2), if the concrete ...

New techniques for trail bounds and application to differential trails in Keccak
IACR Transactions on Symmetric Cryptology, 2017 We present new techniques to efficiently scan the space of high-probability differential trails in bit-oriented ciphers. Differential trails consist in sequences of state patterns that we represent as ordered lists of basic components in order to arrange
