Improved nonlinear invariant attack

Witrynaken using invariant attacks, i.e., invariant subspace or nonlinear invariant attacks. This work analyzes the resistance of such ciphers against invari-ant attacks and reveals the precise mathematical properties that render those attacks applicable. As a rst practical consequence, we prove that some ciphers including Prince, Skinny-64 and … Witrynarapid development recently. Due to their relatively simple key schedule, nonlinear invari-ant attacks have been successfully applied to several families of lightweight block ciphers. This attack relies on the existence of a nonlinear invariant g : Fn 2!F for the round function F k so that g(x) + g(F k(x)) is constant for any input value x ...

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 ...

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.

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. china star kearnyWitryna1 paź 2024 · Those attacks require only a handful of plaintext–ciphertext pairs and have minimal computational costs. Moreover, the nonlinear invariant attack on the underlying (tweakable) block cipher can be extended to a ciphertext-only attack in well-known modes of operation such as CBC or CTR. china star in south holland ilWitryna7 kwi 2024 · このサイトではarxivの論文のうち、30ページ以下でCreative Commonsライセンス（CC 0, CC BY, CC BY-SA）の論文を日本語訳しています。 china star ibis plazaWitryna4 gru 2016 · In this paper we introduce a new type of attack, called nonlinear invariant attack.
