Research of Digital Signature Algorithm Based on Elliptic Curve

基于椭圆曲线的数字签名技术具有安全性高、运算量小、密钥短、处理速度快、存储空间小等优点,能够完成身份验证、保证数据完整性、防抵赖等,因此,被广泛应用于信息安全领域。文章着重研究椭圆曲线数字签名算法的签名和验证算法效率,并编写快速算法的程序,与经典算法程序比较,执行时间缩短约38.11。

Elliptic curve digital signature technology has high safety,low computation,short key,merit of fast processing speed,small storage and so on. We can authenticate,ensure data integrity,non repudiation and so on via it. So,it has been widely used in the field of information security. The paper focuses on efficiency of the signature and verification algorithm based on the elliptic curve digital signature algorithm,and develops the program of fast algorithm. Compared with classical algorithm program,execution time is shortened about 38. 11.
