摘要
原子性是设计电子支付协议时应考虑的重要性质。文章介绍了电子支付系统的原子性概念,分析了一些重要电子支付协议的原子性,论述了原子性电子支付协议的实现策略,描述了两个著名的原子性电子支付协议——NetBill和Anonymous Atomic Transaction Protocol的协议实现,基于两阶段提交策略提出了一种新的原子性实现方法并用于构造原子性电子合同签署协议,就复杂电子交易模式的原子性支付问题进行了探讨,指出了电子支付原子性研究的最新发展和亟待解决的公开问题。
Atomicity is one of the most important property of electronic commerce payment. In this paper, the basic concept of atomicity in electronic commerce transaction is introduced. The atomicity of some important payment pro- tocols is analysed. The technical strategies of implementing atomic electronic payment protocol are discussed. The im- plementation of two famous atomic payment protocol, NetBill and Anonymous Atomic Transaction Protocol, are de- scribed detailedly. A new method for realizing atomicity is presented and used to design a atomic electronic contract signing protocol utilizing two-phase commitment with introduction of Trsted Third Party. The atomicity problem about complex electronic exchange mode is explored. The new developments about researches of atomicity of elec- tronic payment are pointed out.
