Abstract :
DHA-256 is a dedicated hash function, which is a variation of SHA-256 and designed to enhance SHA-256 security. In this paper, we show one-block second preimage and preimage attacks on 27-step DHA-256 with the time complexity of 2224.45 compression function operations and 232 × 9 words memory.
