数字签名标准(DSS)的理论研究与实现

随着信息和信息技术的发展,电子数据交换逐步成为人们交换的主要形式,密码在信息安全中的应用将会不断拓宽,信息安全对密码的依赖会越来越大。介绍了密码体系中数字签名DSS,主要阐述了它的快速实现方法和主要步骤,包括DSS的主要算法:大素数的寻找,蒙特卡罗算法,高次幂的模指数剩余计算,模逆的计算。给出了DSS在计算机中的模拟过程,并对其安全性进行了分析和说明。

Theory of Digital Signature Standard Technology and Its Applications

The electronics data exchange become the main form that people exchange gradually.The cryptography will open widely and continuously in application of the information safety.The information safety would be more and more counting on the cryptography.This article describes one of the cipher systems:data signature system(DSS).Primarily discuss the quick method to realize DSS and its primary steps which includes the primary arithmetic of the DSS:finding big prime number,Monte Carlo arithmetic,the residual calculate to mod exponent with high power,the arithmetic to power adverse.This article gives the computer programs to simulate the process DSS.And it analyses and explains the security of DSS.
