Upon the problems mentioned above, this paper focuses on the following work:? Analyzes the advantages and disadvantages for the key researches both in and abroad;? Studies some existing international standards and protocols including SET and ASC X9;? Gives the designing rules for the secure scheme then proposes a general simple model for mobile payment;? A secure scheme called SeMo is designed according to the different security needs for lineate links and wireless ones;? Analyzes the security for the scheme still basing on the two distinct links, which improves the scheme fully fulfilling the security requirements such as: authentication, integrity, confidentiality and non-repudiation.

针对上述问题，本文作了以下几点工作：●分析了国内外对移动支付研究的现有关键技术的优缺点；●学习了一些现有的国际金融规范和标准为准则；●借鉴安全电子交易模型方案，并参考了ASC的X9系列规范，提出一个简单可行的移动支付一般模型；●根据该模型尝试着根据无线和有线两个不同接口对安全性的需要，设计出移动支付系统的安全方案SeMo；●然后再根据接口的不同对该安全方案进行分析，证明该方案能解决移动支付的安全问题，也就是手持设备的认证问题以及数据保密性、完整性等问题。
