Second Preimage Attack on SHAMATA-512

We present a second preimage attack on SHAMATA-512, which is a hash function of 512bit output and one of the first round candidates of the SHA-3 competition. The attack uses differential paths that hold with a probability one and a meet-in-the-middle approach to find
