MILP-Aided Related-Tweak/Key Impossible Differential Attack and its Applications to QARMA, Joltik-BC
IEEE Access, 2019 In this paper, we study the relation of related-tweak/key impossible differentials with single-key ones. Following a heuristic strategy, we can derive longer related-tweak/key impossible differentials from single-key ones. We implement this strategy with

Accurate Estimate of the Advantage of Impossible Differential Attacks
IACR Transactions on Symmetric Cryptology, 2017 Impossible differential attacks, which are taking advantage of differentials that cannot occur, are powerful attacks for block cipher primitives. The power of such attacks is often measured in terms of the advantage — number of key-bits found during the ...

Private Matchings and Allocations [PDF]
, 2016 We consider a private variant of the classical allocation problem: given k goods and n agents with individual, private valuation functions over bundles of goods, how can we partition the goods amongst the agents to maximize social welfare?

Impossible Differential Cryptanalysis of Surge
IOP Conference Series: Earth and Environmental Science, 2020 Abstract In 2018, Li Lang et al. proposed a new lightweight block cipher which is called Surge. Its block size is 64-bit, and the length of key size is 64/80/128-bit, respectively. They also proved that the cipher has good performance on security and effectively resists on differential attack, linear attack and algebraic attack.

Multiple Impossible Differential Attacks for ForkAES
Security and Communication Networks, 2022 To yield a highly efficient authentication encryption design for very short messages, the tweakable forkcipher is proposed, which is a tweakable block cipher that uses forking construction to produce two output blocks. The designers also presented ForkAES, a forkcipher that is based on the round function of AES and the tweakable variant of KIASU ...

Impossible Differential Cryptanalysis of 8-Round Deoxys-BC-256
IEEE Access, 2018 Deoxys is a third-round candidate of the CAESAR authenticated encryption competition. In this paper, we present the first cryptanalysis of Deoxys in the single-key model.

Integral and impossible‐differential attacks on the reduced‐round Lesamnta‐LW‐BC
IET Information Security, 2022 Lesamnta‐LW‐BC is the internal block cipher of the Lesamnta‐LW lightweight hash function, specified in ISO/IEC 29192‐5:2016. It is based on the unbalanced Feistel network and Advanced Encryption Standard round function.
