A related-key boomerang distinguishing attack of Threefish-256
Wuhan University Journal of Natural Sciences, 2012The block cipher Threefish is the main component of Skein, which is based on ARX. Based on the efficient algorithms for calculating the differential of modular addition, we extend local collisions of Threefish-256 to more round by using related-key differential of addition in this paper.

Related-Key Boomerang Attacks on KATAN32/48/64
2013KATAN/KTANTAN is a family of hardware oriented block ciphers proposed at CHES 2009. Although the KTANTAN family have been broken by a meet-in-the-middle approach, the KATAN family are secure at present. In this paper, we investigate the KATAN family in the related-key boomerang framework with several techniques.

Improved Related-Tweakey Boomerang Attacks on Deoxys-BC
2018This paper improves previous distinguishers and key recovery attacks against Deoxys-BC that is a core primitive of the authenticated encryption scheme Deoxys, which is one of the remaining candidates in CAESAR. We observe that previous attacks by Cid et al. published from ToSC 2017 have a lot of room to be improved.

Memoryless Related-Key Boomerang Attack on 39-Round SHACAL-2
2009SHACAL-2 is a 64-round block cipher based on the compression function of the hash function standard SHA-256. It has a 256-bit block size and a variable length key of up to 512 bits. Up to now, all attacks on more than 37 rounds require at least 2235 bytes of memory.
