【摘要】 在椭圆曲线密码体制中,在FP域的运算是必不可少的。这里介绍了FP域的运算算法及特点,通过硬件描述语言VHDL完成了在FP域的模乘与模逆运算的设计。通过设计的优化,将模乘与模逆运算中所涉及的加法器、减法器以及比较器都转化为加法器予以实现,在没有改变实现速度的基础上节省了2/3的逻辑资源。通过Modelsim仿真工具,采用一种联合测试方法同时将模乘与模逆进行联合仿真,验证了设计的正确性。更多还原

【Abstract】 The operation in field is essential in elliptic curve cryptography.The algorithm and characteristics of operation in field are described.The algorithm of model multiplication and model inverse in field is designed with VHDL.By design optimization,the adder,subtracter and comparer of model multiplication and model inverse is all implemented with adder,thus saving 2/3 hardware resources without any decreasing of operation speed.The simulation with Modelsim in combination of Model multiplication and model inverse this design is correct and feasible.更多还原
