Witryna1 paź 2024 · Invariant subspace attack is a novel cryptanalytic technique which breaks several recently proposed lightweight block ciphers. In this paper, we propose a new method to bound the dimension of some invariant subspaces in a class of lightweight block ciphers which have a similar structure as the AES but with 4-bit Sboxes.

Witryna[Weak] Structural Invariant Attacks. Most symmetric ciphers can be di-vided into two distinct parts: a set of relatively simple [linear] transformations which mix bits together, and a set of non-linear components (Boolean functions or S-boxes). We call a \Structural Invariant Attack" an attack where 1) there is Witryna10 kwi 2024 · Based on this invariant probability distribution, we define a metric for the risk of the state of the nonlinear stochastic process going out of the secure domain and propose an optimization framework to minimize this metric, thus increase the mean first time when the state starting at the synchronous state hits the boundary of the secure …
