摘要
针对e-Cash交易协议的匿名性和原子性两者之间存在的矛盾,在对多个e-Cash方案及协议属性关系分析研究的基础上,采用离线可信第三方的方式,提出并建立了匿名原子的e-Cash交易协议模型,并对其原子性进行了证明.协议模型不仅克服了在线可信第三方匿名原子交易协议的缺陷,而且使关于协议属性的讨论抽象至与算法细节无关的层次之上,解决了难以直接确定协议属性本质的问题.
Atomicity and Anonymity are necessary for reliable and security electronic commerce transaction and the guarantee of participants' interests. However, there is trade-off between them. The model of anonymous atomic e-Cash transaction protocol with off-line TTP (Trust Third Party) under unreliable communication is presented. In the model, we purposely abstract away as much purely mathematical detail as possible. The model not only overcomes the weakness of anonymous atomic transaction protocol with on-line TTP, but also meets high efficient and practicability.
