Abstract: In this paper, we present a preimage attack on reduced versions of Keccak hash functions. We use our recently developed toolkit CryptLogVer for generating CNF (conjunctive normal form) which is passed to the SAT solver PrecoSAT. We found preimages for some reduced versions of the function and showed that full Keccak function is secure against the presented attack.
