Abstract：
 Present invention belongs to electronic signature technology field. It features said register file containing 32 sub-registers, in the signature or authenticating, respectively fixed storing the data need to proceed modular multiplication and elliptic curve point operation in different sub-register domain, configuring intermediate result to different another sub - register domain, respectively storing two stage two stage different calculation result of signature and authenticating in two different sub-registers for public use in authenticating signature comparison. Present invention uses less register file, simplifying elliptic curve cipher chip structure and raising data throughput rate.
