Security of Poseidon hash function against non-binary differential and linear attacks

Kovalchuk, L.; Oliynykov, R.; Rodinko, M. (Кібернетика та системний аналіз, 2021)

In this work we build the security estimations of Poseidon hash function against non-binary linear and differential attacks. We adduce the general parameters for the Poseidon hash function that allow using this hash function ...
Upper bounds of maximum values of average differential and linear characteristic probabilities of feistel cipher with adder modulo 2^m

Alekseychuk, A.; Kovalchuk, L. (2006)

The paper discusses the Feistel cipher with a block size of n = 2m, where the addition of a round key and a part of an incoming massage in each round is carried out modulo 2^m. In order to evaluate the security of such ...
