摘要
针对Tenca提出的基为8的Montgomery模乘器,采用基为64的改进设计,使其在不同运算长度下,运算速度比Tenca的设计平均提高了48%。同时对硬件设计进行了优化,缩短了关键路径的延迟。该设计具有良好的可扩展性,能够支持任意位数的模乘运算,可广泛应用于不同性能和面积需求的公钥密码协处理器设计。
An improved version of Montgomery multiplier was proposed basing the Tenca＇s word based radix-8 Montgomery multiplier. Radix-64 was used for our design. The performance was improved up to 48% comparing to the Tenca＇s design. Furthermore, the critical path was shortened by adjusting the data-path. The proposed multiplier is also able to work with any precision of the input operands and can suitable to various public key cryptosystem.
