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.

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

A Note on Related-Tweakey Impossible Differential Attacks
IACR Communications in CryptologyIn this note we review the technique proposed at ToSC 2018 by Sadeghi et al. for attacks built upon several related-tweakey impossible differential trails. We show that the initial encryption queries are improper and lead the authors to misevaluate a filtering value in the key recovery phase.

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.

Dialga: A Family of Low-Latency Tweakable Block Ciphers Using Multiple Linear Layers
IACR Transactions on Symmetric CryptologyIn this paper, we propose Dialga, a family of low-latency tweakable block ciphers designed to support 128/256-bit tweaks and 256-bit keys. Dialga achieves significantly small latency by leveraging multiple novel strategies.
