Improved Rectangle Attacks on SKINNY and CRAFT
IACR Transactions on Symmetric Cryptology, 2021 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 = E1 ∘ E0, to construct a distinguisher for E with probability p2q2 by concatenating two short ...

A Security Analysis of Deoxys and its Internal Tweakable Block Ciphers
IACR Transactions on Symmetric Cryptology, 2017 In this article, we provide the first independent security analysis of Deoxys, a third-round authenticated encryption candidate of the CAESAR competition, and its internal tweakable block ciphers Deoxys-BC-256 and Deoxys-BC-384.

Differential Cryptanalysis on Block Cipher Skinny with MILP Program
Security and Communication Networks, Volume 2018, Issue 1, 2018., 2018 With the widespread use of RFID technology and the rapid development of Internet of Things, the research of lightweight block cipher has become one of the hot issues in cryptography research. In recent years, lightweight block ciphers have emerged and are widely used, and their security is also crucial.

Analysis of AES, SKINNY, and Others with Constraint Programming
IACR Transactions on Symmetric Cryptology, 2017 Search for different types of distinguishers are common tasks in symmetrickey cryptanalysis. In this work, we employ the constraint programming (CP) technique to tackle such problems.

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 ...
