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.

New Related-Tweakey Boomerang and Rectangle Attacks on Deoxys-BC Including BDT Effect [PDF]

, 2020
In the CAESAR competition, Deoxys-I and Deoxys-II are two important authenticated encryption schemes submitted by Jean et al. Recently, Deoxys-II together with Ascon, ACORN, AEGIS-128, OCB and COLM have been selected as the final CAESAR portfolio ...

Improved Related-Tweakey Rectangle Attacks on Reduced-round Deoxys-BC-384 and Deoxys-I-256-128 [PDF]

, 2020
Deoxys-BC is the core internal tweakable block cipher of the authenticated encryption schemes Deoxys-I and Deoxys-II. Deoxys-II is one of the six schemes in the final portfolio of the CAESAR competition, while Deoxys-I is a 3rd round candidate.

Related-Tweakey Impossible Differential Attack on Reduced-Round Deoxys-BC-256 [PDF]

, 2018
Deoxys-BC is the internal tweakable block cipher of Deoxys, a third-round authenticated encryption candidate at the CAESAR competition. In this study, by adequately studying the tweakey schedule, we seek a six-round related-tweakey impossible ...

Dialga: A Family of Low-Latency Tweakable Block Ciphers Using Multiple Linear Layers

IACR Transactions on Symmetric Cryptology
In 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.

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 ...

Computing the Differential Probability of a Word-Based Block Cipher

Cryptography
Differential cryptanalysis is one of the fundamental cryptanalysis techniques to evaluate the security of the block cipher. In many cases, resistance to differential cryptanalysis is proven through the upper bound of the differential characteristic ...
