Related-Tweak Statistical Saturation Cryptanalysis and Its Application on QARMA
Related-Tweak Statistical Saturation KDIB Conditional Equivalence
2019/3/1
Statistical saturation attack takes advantage of a set of plaintext with some bits fixed while the others vary randomly, and then track the evolution of a non-uniform plaintext distribution through th...
Impossible Differential Attack on QARMA Family of Block Ciphers
impossible differential attack truncated differential QARMA
2018/4/12
QARMA is a family of lightweight tweakable block ciphers, which is used to support a software protection feature in the ARMv8 architecture. In this paper, we study the security of QARMA family against...
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...
Meet-in-the-Middle Attack on QARMA Block Cipher
QARMA Lightweight Tweakable Block Cipher Meet-in-the-Middle Attack
2016/12/29
QARMA is a recently published lightweight tweakable block cipher, which has been used by the ARMv8 architecture to support a software protection feature. In this paper, using the method of MITM, we gi...
The QARMA Block Cipher Family -- Almost MDS Matrices Over Rings With Zero Divisors, Nearly Symmetric Even-Mansour Constructions With Non-Involutory Central Rounds, and Search Heuristics for Low-Latency S-Boxes
Tweakable Block Ciphers Almost MDS Matrices Even-Mansour Schemes
2016/5/9
We introduce and analyse a family of Almost MDS matrices defined over a ring with zero divisors that allows us to encode rotations in its operation while maintaining the minimal latency associated to ...
