摘要: 提出一种改进的基于剩余数系的Montgomery模乘算法。该算法通过对相对固定的参数进行预计算,从而减少运算过程中模乘运算的次数,与Bajard J C提出的算法(IEEE计算机会刊,2004年第6期)相比减少300/(2k+8)。同时基于改进算法提出数据长度可伸缩的硬件模乘器结构设计,并在0.18 μm SMIC工艺下进行综合。性能分析表明,该设计在运算速度上有明显的提高。

Abstract: This paper presents an improved Residue Number System(RSN) Montgomery modular multiplication algorithm, which is optimized by pre-computing the constant parameter. Compared to the Bajard J C(IEEE Transactions on Computers, 2004, No.6) algorithm, the number of modular multiplication is reduced by 300/(2k+8) percent. A hardware design of scalable modular multiplier is proposed, which is implemented on 0.18 μm SMIC process. Result shows that the design has advanced performance.
