一个基于移动代理的优化支付协议

移动代理是能在异构网络中漫游的一种软件实体，它极大地改善了分布式系统的性能，被认为在未来的电子商务中必将起到很重要的作用．然而，许多新的安全问题也随之而来．这些安全问题已被看做是移动代理技术得到更广泛应用的主要障碍之一．利用可验证秘密共享和正交验证理论，提出了一个基于移动代理的优化支付协议．协议提供了很好的安全性．同时，在不泄露所购买商品的情况下，能够使移动代理对所购买商品进行验证．另外，最小限度地使用了可信任第3方，除非出现欺诈行为或者协议提前终止．否则可信任的第3方为脱线运行．

An Optimistic Payment Protocol Based on Mobile Agents

Mobile agent systems are identified as a programming paradigm that allows flexible structuring of distributed computation over the Internet. It is expected that they will play an important role in the future information society and especially in e-commerce applications. Despite their benefits, their adoption is largely hampered by the new security issues they raise. In this paper, by using verifiable secret sharing scheme and the theory of cross validation, an optimistic payment protocol based on mobile agents is proposed. This protocol can protect the confidentiality of sensitive payment information carried by mobile to receive is the one he is paying for without exposing it someone is misbehaving or prematurely aborting. Moreover, the trusted third party is offline unless
