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.

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.

Improved Search for Integral, Impossible-Differential and Zero-Correlation Attacks: Application to Ascon, ForkSKINNY, SKINNY, MANTIS, PRESENT and QARMAv2 [PDF]
, 2023 Integral, impossible-differential (ID), and zero-correlation (ZC) attacks are three of the most important attacks on block ciphers. However, manually finding these attacks can be a daunting task, which is why automated methods are becoming increasingly ...

Impossible Boomerang Attacks Revisited
IACR Transactions on Symmetric CryptologyThe impossible boomerang (IB) attack was first introduced by Lu in his doctoral thesis and subsequently published at DCC in 2011. The IB attack is a variant of the impossible differential (ID) attack by incorporating the idea of the boomerang attack. In

Differential Power Analysis of the SKINNY Family of Block Ciphers [PDF]
, 2020 The SKINNY family of lightweight block ciphers is well-researched in terms of standard cryptanalysis, but little has been done in the field of power analysis attacks. By sequentially dividing and conquering, univariate Differential Power Analysis attacks

Generalized Related-Key Rectangle Attacks on Block Ciphers with Linear Key Schedule: Applications to SKINNY and GIFT [PDF]
, 2020 This paper gives a new generalized key-recovery model of related-key rectangle attacks on block ciphers with linear key schedules. The model is quite optimized and applicable to various block ciphers with linear key schedule. As a proof of work, we apply
