Related-tweakey impossible differential attack on reduced-round Deoxys-BC-256

Science China Information Sciences, 2019
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 distinguisher of Deoxys-BC-256, which is transformed from a 3.5-round single-key impossible distinguisher of ...

Generalized related-key rectangle attacks on block ciphers with linear key schedule: applications to SKINNY and GIFT [PDF]

Designs, Codes, and Cryptography, 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

Improved Related-Tweakey Boomerang Attacks on Deoxys-BC

Lecture Notes in Computer Science, 2018
This 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.

Single Tweakey Cryptanalysis of Reduced-Round SKINNY-64 [PDF]

Lecture Notes in Computer Science, 2020
Skinny is a lightweight tweakable block cipher which received a great deal of cryptanalytic attention following its elegant structure and efficiency. Inspired by the Skinny competitions, multiple attacks on it were reported in different settings (e.g ...

Generalized impossible differential attacks on block ciphers: application to SKINNY and ForkSKINNY [PDF]

Designs, Codes, and Cryptography
Impossible differential cryptanalysis is a crucial cryptanalytical method for symmetric ciphers. Given an impossible differential, the key recovery attack typically proceeds in two steps: generating pairs of data and then identifying wrong keys using the
