Tweaks and Keys for Block Ciphers: the TWEAKEY Framework [PDF]

, 2015
We propose the TWEAKEY framework with goal to unify the design of tweakable block ciphers and of block ciphers resistant to related-key attacks. Our framework is simple, extends the key-alternating construction, and allows to build a primitive with ...

Mind the Gap - A Closer Look at the Security of Block Ciphers against Differential Cryptanalysis [PDF]

, 2018
Resistance against differential cryptanalysis is an important design criteria for any modern block cipher and most designs rely on finding some upper bound on probability of single differential characteristics. However, already at EUROCRYPT'91, Lai et al.

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.

Generalized Impossible Differential Attacks on Block Ciphers: Application to SKINNY and ForkSKINNY [PDF]

Impossible differential cryptanalysis is a crucial cryptanalytical method for symmetric ciphers. Given an impossible differential, the key recovery attack typically proceeds in two steps: generating pairs of data and then identifying wrong keys using the

Optimizing Key Recovery in Impossible Cryptanalysis and Its Automated Tool [PDF]

Impossible differential (ID) cryptanalysis and impossible boomerang (IB) cryptanalysis are two methods of impossible cryptanalysis against block ciphers. Since the seminal work introduced by Boura et al.

Impossible Differential Cryptanalysis on Deoxys-BC-256 [PDF]

, 2018
Deoxys is a third-round candidate of the CAESAR competition. This paper presents the first impossible differential cryptanalysis of Deoxys-BC-256 which is used in Deoxys as an internal tweakable block cipher.

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.

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 ...
