Optimizing Rectangle Attacks: A Unified and Generic Framework for Key Recovery [PDF]
, 2022 The rectangle attack has shown to be a very powerful form of cryptanalysis against block ciphers. Given a rectangle distinguisher, one expects to mount key recovery attacks as efficiently as possible.

Sonikku: Gotta Speed, Keed! A Family of Fast and Secure MACs [PDF]
A message authentication code (MAC) is a symmetric-key cryptographic function used to authenticate a message by assigning it a tag. This tag is a short string that is difficult to reproduce without knowing the key.

Probabilistic Extensions: A One-Step Framework for Finding Rectangle Attacks and Beyond [PDF]
In differential-like attacks, the process typically involves extending a distinguisher forward and backward with probability 1 for some rounds and recovering the key involved in the extended part.

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.

A Note on Related-Tweakey Impossible Differential Attacks [PDF]
In this short note we review the technique proposed at ToSC 2018 by Sadeghi et al. for attacks built upon several related-tweakey impossible differential trails.
