Mind Your Path: On (Key) Dependencies in Differential Characteristics

open access: yesIACR Transactions on Symmetric Cryptology, 2022
Cryptanalysts have been looking for differential characteristics in ciphers for decades and it remains unclear how the subkey values and more generally the Markov assumption impacts exactly their probability estimation.

Subspace Trail Cryptanalysis and its Applications to AES

open access: yesIACR Transactions on Symmetric Cryptology, 2017
We introduce subspace trail cryptanalysis, a generalization of invariant subspace cryptanalysis. With this more generic treatment of subspaces we do no longer rely on specific choices of round constants or subkeys, and the resulting method is as such a ...

Improved Security Evaluation of SPN Block Ciphers and its Applications in the Single-key Attack on SKINNY

open access: yesIACR Transactions on Symmetric Cryptology, 2020
In this paper, a new method for evaluating the integral property, truncated and impossible differentials for substitution-permutation network (SPN) block ciphers is proposed. The main assumption is an explicit description/expression of the internal state
