文中介绍了椭圆曲线点乘的原理与特点,通过硬件描述语言VHDL作为设计输入,完成了椭圆曲线点乘的模平方、模乘、模逆以及总体设计。模平方运算采用并行算法,模逆运算进行了优化,提高了系统的速度;整个系统结构进行了优化处理,节约了一定的硬件资源。文中采用联合仿真以及ANSI X9.62的测试向量,通过Modelsim完成每个模块与系统仿真,验证系统的设计是正确的。 In this paper, the principle and characteristics of elliptic curve point multiplication are introduced. Through the hardware description language VHDL as design input, the square, the modular multiplication, the modulo inverse and the overall design of elliptic curve point multiplication are completed. The modular arithmetic is optimized by using parallel algorithm and modulo inverse arithmetic to improve the speed of the system. The whole system structure is optimized and some hardware resources are saved. In this paper, the co-simulation and ANSI X9.62 test vectors are used to complete each module and system simulation with Modelsim to verify that the system design is correct.
