摘要
数字签名是密码学领域中保障信息安全的一种重要技术,E lGam al数字签名算法的安全性是基于求解离散对数很困难这一问题之上的.介绍了这种签名方案的一种伪签名算法并对整个签名系统的安全性进行了评估和分析.
The digital signature is an important technique that guarantees the security of information in the realm of cryptography, The security of EIGamal digital signature is based on the difficulty in solving the discrete logarithm. This paper introduces an arithmetic method on counterfeiting signature and analyzes and evaluates the security of the whole signature system.
