Abstract: Fair exchange plays an increasingly important role in e-commerce,the contract signing is a specific example of fair exchange.Based on convertible signature scheme and non-interactive verification technology,a new contract signing protocol is proposed.Analysis shows that the new protocol not only possesses the properties of optimism,fairness,timely termination,abuse-freeness and TTP’s statelessness,but also has the characteristic of high-efficiency.
Key words: fair exchange, contract signing, convertible signature, non-interactive verification
摘要: 公平交换在电子商务活动中起着越来越重要的作用,合同签署协议是公平交换的一种具体实例。基于可转化签名思想和非交互的认证技术,提出一个新的合同签署协议,分析表明,新协议不仅具有优化性、公平性、实时终止性、无滥用性、TTP的无状态性等优点,而且具有高效性的特点。
