Improved Attacks on LowMC with Algebraic Techniques [PDF]
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

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.

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 ...

MRHS solver based on linear algebra and exhaustive search [PDF]
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.

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 ...

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 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.

High-Performance Hardware Implementation of MPCitH and Picnic3
Transactions on Cryptographic Hardware and Embedded SystemsPicnic is a post-quantum digital signature, the security of which relies solely on symmetric-key primitives such as block ciphers and hash functions instead of number theoretic assumptions. One of the main concerns of Picnic is the large signature size.
