Cryptanalysis of round-reduced ascon
WebOur cryptanalysis efforts focus on a round reduced Ascon, but only in the encryption phase. This means, the initialization carries out using all the rounds it is meant to, but for the encryption permutation module we experimented with using 1, up to 8 rounds. D. Simplified Ascon Aside from using a round reduced Ascon, which is WebThe improved key recovery attacks on round-reduced variants of these ciphers are then proposed. To the best of our knowledge, they are thus far the best known cryptanalysis of Serpent, as well as the best differential-linear cryptanalysis of Ascon and the best initialization analysis of Grain v1. The results have been fully verified by experiments.

WebOne essential criterion for the evaluation of the 10 finalists is the evidence for their security against attacks like linear and differential cryptanalysis. For Ascon, one of the finalists … WebIn this paper, we propose a new modeling strategy for SAT solvers and derive strong bounds for the round-reduced Ascon permutation. We prove that 4 rounds already ensure that any single characteristic has a differential probability or squared correlation of at most 2−72, and 6 rounds at most 2−108.
WebIn cryptography, a round or round function is a basic transformation that is repeated multiple times inside the algorithm.Splitting a large algorithmic function into rounds simplifies both implementation and cryptanalysis.. For example, encryption using an oversimplified three-round cipher can be written as = ((())), where C is the ciphertext and P is the … Webcan nd a 6-round collision with time complexity 2113. For Ascon-Hash, we can nd a 2-round collision with time complexity 2125. Following the other strategy, we give a practical attack on 2-round Ascon-Xof with a 64-bit output. The time complexity is 215. We search for the characteristics using the MILP technique and the target di erential ...
