摘要
椭圆曲线密码体制已成为公钥密码研究的主流。介绍了椭圆曲线密码体制的一些数学理论基础,对算法的基础模块进行了说明,讨论了软件实现素数域上椭圆曲线密码算法的一种方法,在DSP6205,主频200MHz的环境下,192比特的ECDSA签名速率70次/秒,验证速率60次/秒。最后对椭圆曲线加密体制的研究与实现进行了全面总结,给出了所完成的工作,对椭圆曲线密码体制的应用前景提出了展望。
In recent years,the PKC study focuses on the software implementation of ECC （elliptic curvcryptosystem）.This paper discusses the mathematical basis of elliptic curve cryptosystems,describes the in detailthe implementation of elliptic curve cryptosystem,over prime field,particularly the software implementationof elliptic curves over prime fields on DSP.The results of the implementation in C and the assembler on DSP 6205,200MHz are given.Finally,this paper summarizes the study and implementation of elliptic curve cryptosystem,presents the author’s finished work,and points out the prospect of ECC application.
