Description
Summary:With embarrass of high complexity of Cryptographic hash function （CHF） and difficulty of par-allelizing CHF, a relaxed encryption framework for par-allelizing CHF is proposed after understanding principle of hash value generation for CHF. In relaxed encryption framework, dependences in chain mode for generating hash value are broken so that it is possible to parallelize CHF fully, and the strength of encryption for relaxed frame-work is same as or stronger than that of standard CHF. Furthermore, a performance analytical model is presented to validate proposed framework.
