N.Koblitz和V.Miller在1985年各自独立地提出将椭圆曲线应用于公钥密码系统。SM2椭圆曲线密码算法是国家密码管理局批准的一组算法,在电力自动化通讯中得到了广泛应用。本文介绍了SM2椭圆曲线公钥密码算法和加密解密算法中一部分过程的C语言实现。
In 1981, K. Koblitz and V. Miller independently proposed elliptic curves for public-key cryptosystems. SM2 elliptic curve cryptography algorithm is a group of algorithms approved by the State Password Authority, which has been widely used in power automation communication. This paper introduces the C language implementation of part of the SM2 elliptic curve public key cryptography algorithm and encryption and decryption algorithm.
