Application of digital signature technology becomes more extensive, but many exposed digital signature algorithms have increasingly revealed some shortcomings and deficiencies. Aiming directly at the frequently used digital signature technologies, which are weak to Substitution Attack and Homeostasis Attack, the authors perform the hash transformation on messages before signature. Then, a hash round function is constructed, which simultaneously satisfies the characters of balance, high nonlinearity, strict avalanche criterion and realization of software.
