| 摘 要： | 多移动代理协作的多重数字签名在移动代理技术领域,特别是电子商务领域,有着广阔的应用前景。本文鉴于移动代理的安全问题,针对“主从代理协作”这一新兴概念,提出了一种基于ElGamal密码系统和ElGamal密码系统在DSS(数字签名标准)中变换形式的多重数字签名方案,并通过一个具体的商务案例分析其安全性和有效性,得出了若干结论。

| Abstract: | Multi-signature based on cooperation of multi-mobile agents has the wide prospect on mobile agent tech- nique application especially on E-commerce. Aiming at a new concept Cooperation of master agent & slave agents, this paper proposes a new kind of multi-signature mechanlsm based on ElGamal cryptography and its variant form in DSS (Digital Signature Standard) for the serious security problems. Then it makes the analysis for the security & va- lidity of the mechanism and draws some conclusions through a detailed E-commerce example. |
