KATAN and KTANTAN -- A Family of Small and Efficient Hardware-Oriented Block Ciphers
TL;DR: A new family of very efficient hardware oriented block ciphers divided into two flavors, which is more compact in hardware, as the key is burnt into the device (and cannot be changed), and achieves encryption speed of 12.5 KBit/sec.
Book ChapterDOI
The Rectangle Attack - Rectangling the Serpent
TL;DR: In this paper, the authors presented attacks on 7-round, 8-round and 10-round variants of AES's Serpent cipher with all key lengths and 256-bit keys.
Book ChapterDOI
Related-Key boomerang and rectangle attacks
TL;DR: In this article, the boomerang attack and the rectangle attack are combined with related-key differentials, and the new combination is applicable to many ciphers, and demonstrate its strength by introducing attacks on reduced-round versions of AES and IDEA.

A Framework for Iterative Hash Functions — HAIFA ?
Eli Biham,Orr Dunkelman +1 more
TL;DR: The HAsh Iterative FrAmework (HAIFA) as mentioned in this paper is a generalization of the Merkle-Damgard construction that allows for an online computation of the hash function in one pass with a fixed amount of memory independently of the size of the message.
Book ChapterDOI
Key recovery attacks of practical complexity on AES-256 variants with up to 10 rounds
TL;DR: Ateniese et al. as mentioned in this paper showed that AES-256 can be broken in 10 rounds with complexity which is feasible, using only two related keys and 239 time to recover the complete 256-bit key of a 9-round version of AES256.
