TRIFLE is a Round 1 candidate of the NIST Lightweight Cryptography Standardization process. In this paper, we present an interesting 1-round iterative differential characteristic of the underlying blo...
Related-Tweakey Impossible Differential Attack on Reduced-Round Deoxys-BC-256
related-tweakey impossible di erential attack tweakable block cipher Deoxys-BC-256
2018/7/17
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 s...
MILP-Aided Related-Tweak/Key Impossible Differential Attack and Its applications to QARMA, Joltik-BC
Tweakable block cipher Impossible differential attack Related-Tweakey
2018/2/9
In this paper, we study the relation of single-key impossible differentials with the related-tweakey/key ones and propose an interesting algorithm that can efficiently derive longer related-tweakey/ke...
Impossible Differential Cryptanalysis on Deoxys-BC-256
authenticated encryption block cipher Deoxys-BC
2018/1/15
Deoxys is a third-round candidate of the CAESAR competition. This paper presents the first impossible differential cryptanalysis of Deoxys-BC-256 which is used in Deoxys as an internal tweakable block...
Impossible-Differential and Boomerang Cryptanalysis of Round-Reduced Kiasu-BC
cryptanalysis tweakable block cipher
2016/12/29
Kiasu-BC is a tweakable block cipher proposed by Jean et al. at ASIACRYPT 2014 alongside their TWEAKEY framework. The cipher is almost identical to the AES-128 except for the tweak, which renders it a...
Kiasu-BC is a tweakable block cipher presented within the TWEAKEY framework at AsiaCrypt 2014. Kiasu-BC is almost identical to AES-128, the only difference to AES-128 is the tweak addition, where the ...
We state the design flaws of the 1-round block cipher SHAMATA-
BC, designed by Fleishmann and Gorski by using the building
blocks of SHAMATA hash function. We fix the flaws and then show that
the a...
