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 ...
