Witryna23 kwi 2024 · Abstract There are numerous results on nonlinear invariant attacks on T-310. In all such attacks found so far, both the Boolean functions and the cipher wiring were contrived and chosen by the attacker. Witryna14 lut 2024 · A new approach to invariant subspaces and nonlinear invariants is developed. This results in both theoretical insights and practical attacks on block ciphers. It is shown that, with minor modifications to some of the round constants, Midori-64 has a nonlinear invariant with $$2^{96} + 2^{64}$$ 296+264 corresponding weak keys. … opticsre.com

Witryna11 kwi 2024 · A general foundation of fooling a neural network without knowing the details (i.e., black-box attack) is the attack transferability of adversarial examples across different models. Many works have been devoted to enhancing the task-specific transferability of adversarial examples, whereas the cross-task transferability is nearly … 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 … portland maine ferries to nova scotiaWitryna1 sie 2024 · There are basically three steps in SCREAM: encryption of the plaintext block, associated data processing and tag generation.

Improved nonlinear invariant attack

WitrynaThe core idea of the nonlinear invariant attack is to detect a nonlinear Boolean function gsuch that g(F(x k)) = g(x k) c= g(x) g(k) c 8x for many keys k, where cis a constant in F 2. Keys for which this equality holds will be called weak keys. The function gitself is called nonlinear invariant in this paper. 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
