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. WitrynaIn this paper we introduce a new type of attack, called nonlinear invariant attack. As application examples, we present new attacks that are able to distinguish the full …

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 WitrynaIn this paper, to better understand and improve attack and defense, we first take a bottom-up perspective to describe the correlations between latent factors and observed data, then analyze the effect of domain shift on DNNs induced by attack and finally develop our causal graph, namely Domain-attack Invariant Causal Model (DICM). trunc int rounddown 違い
