  abstract = {DHA(Double Hash Algorithm)-256 is a dedicated hash function with message length of 512 bits and output length of 256 bits. ``Double'' means that each message word which is generated by the message expansion algorithm is used twice in a step. Our Design goal is to enhance the security of SHA-256. The step function and the message expansion of DHA-256 has almost same resource as SHA-256 but provides higher security bound against recent proposed attacks.},
