Key Guessing Strategies for Linear Key-Schedule Algorithms in Rectangle Attacks [PDF]
, 2022 When generating quartets for the rectangle attacks on ciphers with linear key-schedule, we find the right quartets which may suggest key candidates have to satisfy some nonlinear relations. However, some quartets generated always violate these relations,

Multiforked Iterated Even-Mansour and a Note on the Tightness of IEM Proofs [PDF]
The Iterated Even-Mansour (IEM) construction was introduced by Bogdanov et al. at EUROCRYPT 2012 and can be seen as an abstraction or idealization of blockciphers like AES.

Improved Search for Integral, Impossible-Differential and Zero-Correlation Attacks: Application to Ascon, ForkSKINNY, SKINNY, MANTIS, PRESENT and QARMAv2 [PDF]
Integral, impossible-differential (ID), and zero-correlation (ZC) attacks are three of the most important attacks on block ciphers. However, manually finding these attacks can be a daunting task, which is why automated methods are becoming increasingly ...

Improved Rectangle Attacks on SKINNY and CRAFT [PDF]
The boomerang and rectangle attacks are adaptions of differential cryptanalysis that regard the target cipher $E$ as a composition of two sub-ciphers, i.e., $E = E_{1}\circ E_{0}$, to construct a distinguisher for $E$ with probability $p^{2}q^{2}$ by ...
