基于移动Agent的安全电子拍卖系统的构建

Constructoion of Mobile Agent-based Secure Electronic Auction System

随着电子商务技术的日益发展,移动Agent技术可以用来进行市场调查,商品买 卖及离线拍卖等?事实证明只有当用移动Agent构建的系统的安全性得到确切的保证后,才 能被大众用户所接受?该文提出了一个基于移动Agent的电子拍卖协议,并以此协议构建了 一个实际的系统?系统中采用了主从结构,在认证过程中要求Agent向拍卖服务器出示许可 证等方法来保证系统的安全性?最后,对协议设计的正确性和效率进行了详尽的分析?

In the area of electronic commerce, the technology of mobile trade agents can be used in the market research, buyer-merchant negotiation and on-lin e auction. Although the benefits resulting from the use of such intelligent assi stants for the end-users are not argued, it is empirically confirmed that Intern et buyers and merchants will use them widely, only when convinced that mobile tr ade agents are secure. This paper presents an agent-based model for collecting a nd evaluating purchase contracts, signed by Internet merchants. It aims to confr ont the security risks derived from mobile trade agents. The model uses a master -slave distributed agent architecture and proposes the authentication of mobile agents to auction servers, through agent permission tokens. In addition, it ana lyzes the security issues of the mobile agent based electronic auction protoco l.
