采用复合武硬件设计方法,通过数学公式推导和电路结构设计,完成了一款GF(2m)域椭圆曲线密码处理器的高效VLSI实现。以低成本为目标,对算术逻辑模块的乘法、约减、平方、求逆,以及控制电路模块都进行了优化设计。按照椭圆曲线密码的不同运算层次,设计了不同层次的控制电路。该处理器综合在中芯国际SMIC0.18μm标准工艺库上.比相关研究的芯片面积节省48%,同时保证了很快的速度。
Through a compound hardware-design method of combining mathematical reasoning and circuit technology, this paper presents a VKSI implementation of ECC processor over GF (2m). Targeting low cost, we finish the optimal design of squaring, reduction, multiplication, inversion in Arithmetic logic module. According to different operation hierarchies, we designed different controlling circuits to match. The ECC processor has been synthesized on SMIC 0.18μm CMOS technology and has an area reduction of 48% comparing to international relevant research, with really fast speed at the same time.
