摘要
数字签名技术是信息安全领域中研究的热点问题之一。在研究椭圆曲线密码体制和经典数字签名过程的基础上,针对明文用哈希函数变换成一个整数和明文嵌入到椭圆曲线上点的不同情况,提出了两种数字签名的改进算法,并进行了正确性验证和安全性分析。改进后的算法加密和验证过程中不需要进行模逆的运算,减少了运算量,降低了对计算机软硬件的要求。
The digital signature technology is one of hot topics in the information security domain.Based on the elliptic curve cryptosystem and the classical digital signature process,we analyze the different situations of using hash function to transform plain text into integer and plain text into points on elliptic curve,and propose two kind of digital signature improvement algorithm.The correctness verification and security analysis is carried out.The improved algorithm does not need modular inversion in the process of encryption and verification.Reduces the amount of computation.The algorithm reduces the requirements of computer hardware and software.
