Parallelizing Cryptographic Hash Function Using Relaxed Encryption Framework

With embarrass of high complexity of Cryptographic hash function (CHF) and difficulty of parallelizing CHF, a relaxed encryption framework for parallelizing 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 framework is same as or stronger than that of standard CHF. Furthermore, a performance analytical model is presented to validate proposed framework.
