公钥密码处理芯片的设计与实现

The Design and Implementation Realization of Public-Key Cryptography Processing Chips

以RSA算法为例,探讨了公钥密码处理芯片的设计与实现.首先提出了公钥密码芯片实现中的核心问题,即大整数模幂运算算法和大整数模乘运算算法的实现;然后针对RSA算法,提出了Montgomery模乘算法的CIOS方法的一种新的快速硬件并行实现方法,其中采用了加法与乘法并行运算以及多级流水线技术以提高性能,较大地减少了乘法运算时间,提高了模乘器的性能.

This paper is based on RSA algorithm and discussed public-key cryptography processing chip design and implementation. At first, it is proposed that long integer modular multiplication is the key problem of public-key crypto-chips. Then, aim at RSA, Montgomery by CIOS method is discussed and parallel operation and pipelining are adopted. So, it can reduce multiplication production time and increase the capability of multiplier.
