高并行可配置的GF(p)域ECC处理器

摘要

A configurable and high parallelism Elliptic Curve Cryptography(ECC) processor over GF(p) to compute point multiplication is proposed based on Transport Triggered Architecture(TTA). The processor can be extended for the different requirement of security by configuring special function units, bus and register files. The Very Long Instruction Word(VLIW) instruction format makes the processor gain the high parallelism. An especial Function Unit(FU) named Montgomery Multiplier Accumulators Unit(MMAU) is designed to accelerate the implementation of the modular multiplication. With a 0.18 μm CMOS cell library, the processor uses 83 Kgates and achieves 0.425 us for a modular multiplication and 2 ms for a point multiplication over GF(p) at 120 MHz when the key length is 192 bit.%提出一种基于传输触发架构的可配置高并行性素域椭圆曲线密码处理器.该处理器用于快速实现点乘运算,通过配置特殊的功能单元、总线以及寄存器文件堆,可针对不同安全需求进行扩展.超长指令字的指令格式使处理器具有高并行性.设计的特殊功能单元MMAU加速了模乘运算的实现.仿真结果表明,在0.18μm CMOS工艺下,处理器所占面积为83 Kgates,能工作在最大120 MHz时钟频率下,可以在0.425 μs和2 ms内完成一次192 bit的模乘和点乘运算.
