Research Abstract

In this research, a processor for accelerating various public key cryptosystem such as RSA cryptosystem which is widely used in current Internet data exchanging and Elliptic Curve cryptosystem which is focused as standard cryptosystem in next generation, was developed. As research achievement, the developed processor had only 10 times smaller chip area and achieved a few to several tens times higher performance, compared with a general processor currently used.
