摘要: 给出了一种公钥密码协处理器的结构,既可以计算定义在Fp上的椭圆曲线的点乘运算,也可以计算应用在RSA中的模幂运算,支持域长度不超过256比特的ECC,长度不超过2 048比特的RSA。该协处理器具有结构简单、实现方便、稍加调整即可满足用户对面积的要求等特点。

Abstract: This paper describes a hardware implementation of a cryptographic processor for RAS and ECC. The processor can not only compute modual exponent of RSA, which length is less than 2 048, but also compute point multiplication of ECC, which length is less than 256. The processor is implemented simply and can adjust area.

Key words: RSA, elliptic curve cryptography(ECC), hardware implementation, processor
