基于电子商务的交易协议

Exchange Protocol Based on Electronic Commerce

基于电子商务的交易协议分为逐步交换协议(GEP)和可信第三方(TTP)协议。逐步交换协议的两个参与主体具有相同的计算能力,通过消息交换实现这类协议。TTP主体通过可信第三方交换消息,实现协议的各种安全目标。该交易协议设计原则包括安全性、匿名性、非否认性、原子性、公平性与效率。

Exchange protocol based on EC （electronic commerce） is composed of GEP（Gradual Exchange Protocol） and TTP（Trutsted Third Party） protocol.Partaken two parts of GEP have same computational ability,and the GEP is realized through exchanging message.TTP protocol is that the message is exchaged through TTP to realize all kinds of safety objects of the protocol.The design principle of exchange protocol includes security,anonymity,non-repudiation,atomicity（）,fairness and efficiency.
