摘要
增值服务在移动通信网络中的重要地位日趋显著。分析了当前基于PayWord构建的方案中存在的透支及低效等问题。基于全局PKI,提出新型移动通信环境中的增值服务支付协议。运用BAN逻辑对协议的安全性目标予以了证明,并对协议的计算复杂度等方面进行了比较分析。结论显示新方案具备适用于特定环境的用户端计算载荷低等众多特性,高效地解决了透支等问题。
Value-added service has become more and more important in mobile communications.The problems of overdraft and low-efficiency consisting in the schemes based on PayWord are analyzed in this paper.Based on PKI,this paper presents new value-added service payment protocols for mobile communications.Then the formalized security proof of the protocol using BAN logic,and the qualitative analysis about its computing complexity are given.Results show that there are many properties such as lightweight computation on the side of customer being applicable to special applied circumstance in the scheme, and the problems such as overdraft are solved with efficiency.
