Design of Secure SOC Multi-type and Multiplexing IP Core of Hash Algorithm
-
Abstract
Based on deep studying interrelation and the similarity of algorithm of SHA-1,SHA-224 and SHA-256,an IP core containing these three kinds of algorithms was developed and redesigned.It speeds up the operation and improves the performance,in particular of saving area,resource optimization and good portability.It meets multilevel security and integration optimization requirements of various clients,supporting double reset,interrupt and low-power mode,as well as reading and writing operations midway.
