【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。更多还原

【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.更多还原
