Abstract: DHA-256 was presented at the Cryptographic Hash Workshop hosted by NIST in November 2005. DHA-256 (Double Hash Algorithm) was proposed to enhance the security of SHA-256. We present a preliminary analysis of the message expansion and give an alternative 9-step local collision for DHA-256.
