MRHS solver based on linear algebra and exhaustive search
Journal of Mathematical Cryptology, 2018 We show how to build a binary matrix from the MRHS representation of a symmetric-key cipher. The matrix contains the cipher represented as an equation system and can be used to assess a cipher’s resistance against algebraic attacks.

New Low-Memory Algebraic Attacks on LowMC in the Picnic Setting
IACR Transactions on Symmetric Cryptology, 2022 The security of the post-quantum signature scheme Picnic is highly related to the difficulty of recovering the secret key of LowMC from a single plaintext-ciphertext pair.

Effect of the difference enumeration attack on LowMC instances
网络与信息安全学报, 2021 The LowMC is an algorithm with low multiplicative complexities.For the parameter with limited data complexities and low number of S-boxes, the difference enumeration attack was proposed, which could theoretically attack all rounds of the LowMC ...

Cryptanalysis of LowMC instances using single plaintext/ciphertext pair
IACR Transactions on Symmetric Cryptology, 2020 Arguably one of the main applications of the LowMC family ciphers is in the post-quantum signature scheme PICNIC. Although LowMC family ciphers have been studied from a cryptanalytic point of view before, none of these studies were directly concerned ...

Improved Attacks on LowMC with Algebraic Techniques
IACR Transactions on Symmetric Cryptology, 2023 The LowMC family of SPN block cipher proposed by Albrecht et al. was designed specifically for MPC-/FHE-/ZKP-friendly use cases. It is especially used as the underlying block cipher of PICNIC, one of the alternate third-round candidate digital signature

Provable Security of SP Networks with Partial Non-Linear Layers
IACR Transactions on Symmetric Cryptology, 2021 Motivated by the recent trend towards low multiplicative complexity blockciphers (e.g., Zorro, CHES 2013; LowMC, EUROCRYPT 2015; HADES, EUROCRYPT 2020; MALICIOUS, CRYPTO 2020), we study their underlying structure partial SPNs, i.e., Substitution ...

Cryptanalysis of Low-Data Instances of Full LowMCv2
IACR Transactions on Symmetric Cryptology, 2018 LowMC is a family of block ciphers designed for a low multiplicative complexity. The specification allows a large variety of instantiations, differing in block size, key size, number of S-boxes applied per round and allowed data complexity. The number of

Differential Attacks by Algebraic Solving on a Series of HE‐Friendly Stream Ciphers
IET Information Security, Volume 2026, Issue 1, 2026.In recent years, many symmetric encryption ciphers have been proposed for homomorphic encryption (HE) applications. Rasta and its variants Masta and Pasta have gradually become a self‐contained series of HE‐friendly stream ciphers. The feature of these ciphers is that a fresh affine layer is randomly generated for each encryption.

Differential Fault Attacks on Privacy Protocols Friendly Symmetric‐Key Primitives: RAIN and HERA
IET Information Security, Volume 2024, Issue 1, 2024.As the practical applications of fully homomorphic encryption (FHE), secure multi‐party computation (MPC) and zero‐knowledge (ZK) proof continue to increase, so does the need to design and analyze new symmetric‐key primitives that can adapt to these privacy‐preserving protocols.
