Computing the Differential Probability of a Word-Based Block Cipher

open access: yesCryptography
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 ...

Improved meet-in-the-middle attack on Joltik-BC-128

open access: yes网络与信息安全学报
The Joltik-BC, adopting the substitution-permutation network structure and Tweakey framework, was a lightweight tweakable block cipher published at ASIACRPYPT 2014. By researching the internal characteristic of the Joltik-BC, a 6-round meet-in-the-middle

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.
