Improved nonlinear invariant attack

Witryna2 paź 2024 · In its basic form, a nonlinear invariant attack is a distinguishing attack. The second and the main contribution of this paper is to obtain precise expressions for the errors of nonlinear invariant attacks in distinguishing a key-alternating cipher from either a uniform random function or a uniform random permutation. WitrynaThe nonlinear invariant attack was introduced at ASIACRYPT 2016 by Todo et al.. The attack has received extensive attention of cryptographic community due to its practical application on the full-round block ciphers SCREAM, iSCREAM, and Midori64. However, the attack heavily relies on the choice of round constants and it becomes inefficient in ...
