[Resource Topic] 2007/476: Dynamic SHA

Welcome to the resource topic for 2007/476

Dynamic SHA

Authors: Xu Zijie


In this paper I describe the construction of Dynamic SHA family of cryptographic hash functions. They are built with design components from the SHA-2 family, but there is function R in the new hash functionh. It enabled us to achieve a novel design principle: When message is changed, different rotate right operation maybe done. It make the system can resistant against all extant attacks.
