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.

Cryptanalysis of Low-Data Instances of Full LowMCv2 [PDF]
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

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 ...

Stream ciphers: A Practical Solution for Efficient Homomorphic-Ciphertext Compression [PDF]
, 2015 International audienceIn typical applications of homomorphic encryption, the first step consists for Alice to encrypt some plaintext m under Bob’s public key pk and to send the ciphertext c = HEpk(m) to some third-party evaluator Charlie.
