Known-key distinguishers on 15-round 4-branch type-2 generalised Feistel networks with single substitution–permutation functions and near-collision attacks on its hashing modes

Generalised Feistel network (GFN) is a popular design for block ciphers and hash functions. The round function of the network often chooses a substitution–permutation (SP) transformation (consists of a subkey XOR, an S-boxes layer and a linear layer). In 2011, Bogdanov and Shibutani provided another...
