Abstract

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

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。
