摘要: 以现有的ElGamal数字签名体制为基础,研究了网络学习系统中的代理数字签名算法:单代理数字签名算法和多代理数字签名算法,与目前用得较多的基于Fiat-Shamir签名体制的代理数字签名算法和基于Guillou-Quisquater签名体制的代理数字签名算法相比,这些算法具有密钥短小、参数规模小、运算速度快和安全性好的优点。

Abstract: The proxy digital signature algorithms based on the ElGamal signature scheme in existence are proposed in e-learning system,and they are mono-proxy digital signature algorithm and multi-proxy digital signature.These digital signature algorithms have the strongpoint of short key,small parameter scale,rapid operation,finer security,and contrast with the proxy digital signature algorithms based on the Fiat-Shamir signature scheme and the Guillou-Quisquater signature scheme.

Key words: e-learning system, digital signature, proxy digital signature
