A new distinguishing attack on reduced round ChaCha permutation [PDF]
Scientific Reports, 2023 This work concentrates on differential-linear distinguishing attacks on the prominent ARX-based permutation ChaCha. Here, we significantly improve the 7-round differential-linear distinguisher for ChaCha permutation by introducing a new path of linear ...

Distinguishing Attack on NORX Permutation
IACR Transactions on Symmetric Cryptology, 2018 NORX is a permutation-based authentication scheme which is currently a third-round candidate of the ongoing CAESAR competition. The security bound of NORX is derived from the sponge construction applied to an ideal underlying permutation.

Grøstl Distinguishing Attack: A New Rebound Attack of an AES-like Permutation
IACR Transactions on Symmetric Cryptology, 2017 We consider highly structured truncated differential paths to mount a new rebound attack on Grøstl-512, a hash functions based on two AES-like permutations, P1024 and Q1024, with non-square input and output registers.

Improved guess-and-determine and distinguishing attacks on SNOW-V
IACR Transactions on Symmetric Cryptology, 2021 In this paper, we investigate the security of SNOW-V, demonstrating two guess-and-determine (GnD) attacks against the full version with complexities 2384 and 2378, respectively, and one distinguishing attack against a reduced variant with complexity 2303.

Cryptanalysis of Rocca and Feasibility of Its Security Claim
IACR Transactions on Symmetric Cryptology, 2022 Rocca is an authenticated encryption with associated data scheme for beyond 5G/6G systems. It was proposed at FSE 2022/ToSC 2021(2), and the designers make a security claim of achieving 256-bit security against key-recovery and distinguishing attacks ...

Generic attacks on small-state stream cipher constructions in the multi-user setting
Cybersecurity, 2023 Small-state stream ciphers (SSCs), which violate the principle that the state size should exceed the key size by a factor of two, still demonstrate robust security properties while maintaining a lightweight design.
