| Abstract: | 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. |
