Dynamic SHA-2

Xu Zijie

Abstract

In this paper I describe the construction of Dynamic SHA-2 family of cryptographic hash functions. They are built with design components from the SHA-2 family, but I use the bits in message as parameters of function G, R and ROTR operation in the new hash functionh. It enabled us to achieve a novel design principle: When message is changed, the calculation will be different. It make the system can resistant against all extant attacks.
