Modular inverse arithmetic plays an important role in elliptic curve cryptography. Based on the analysis of Montgomery modular inversion algorithm, this paper presents a new dual-field modular inversion algorithm, and a novel scalable and unified architecture for Montgomery inverse hardware in finite fields GF(p) and GF(2n) is proposed. Furthermore, this architecture based on the new modular inversion algorithm has been verified by modeling it in Verilog-HDL, and accomplished it under 0.18 μm CMOS technology. The result indicates that our work has better performance and flexibility than other works.

随着信息技术的发展和网络规模不断扩大,网络通信等应用对数据加解密处理提出了更高的要求.可重构计算是将可重构硬件处理单元和软件可编程处理器结合的计算系统.因此采用可重构计算技术来设计密码处理系统,使同一硬件能够高效灵活地支持密码应用领域内的多种算法.同时满足了密码处理对性能和灵活性的要求,提高了密码系统的安全性.论文在分析分组密码算法处理结构的基础上,结合了可重构结构的设计思想和方法,提出了一种可重构密码处理结构模型RCPA,并基于该模型实现了一款验证原型.原型在FPGA上成功进行了验证测试并在0.18μmCMOS工艺标准单元库下进行逻辑综合以及布局布线.实验结果表明,在RCPA验证原型上执行的分组密码算法都可达到较高的性能,其密码处理性能与通用高性能微处理器处理性能相比提高了10～20倍;与其他一些专用可重构密码处理结构处理性能相比提高了1.1～5.1倍.结果说明研究的RCPA模型既能保证分组密码算法应用的灵活性又能够达到较高的性能.
