移动计算网络环境中的认证与小额支付协议

本文在分析现有移动用户认证协议与因特网认证协议基础上,针对移动计算网络的技术特点设计了一个用于移动用户与收费信息服务网络相互认证和用户进行小额电子支付的协议,该协议的新颖之处在于把小额支付方案融入认证协议当中,使移动用户可以利用笔记本电脑或掌上电脑进行付费的网面浏览、购买低价位信息商品以及进行移动电子商务,同时也为移动用户漫游时的记费提供了依据.协议不仅在公共参数的存储空间需求和用户端计算负荷上是适当的,而且可以保护用户不被错误收费,同时提供服务网络防止用户抵赖的合法证据.该协议基于一个全局的公钥基础设施,适用于未来的基于第三代移动通信系统的网络计算环境.

An Authentication and Micropayment Protocol for Mobile Computing Network

According to the requirements of the technique in mobile computing network,an efficient protocol for mutual authentication and electronic payment for mobile computing network is proposed.The paper also demonstrates how a micropayment scheme can be integrated into the authentication protocol.The protocols provide security services required by regular authentication and payment protocols and are efficient in consideration of the storage requirement and computation overheads on subscribers.They protect subscribers from incorrect service charges and provide service providers legal evidences to collect bills that are denied.By using public key infrastructure,they can be used as authentication and payment protocol in future mobile systems.
