摘　　要：本文在分析了基于信用透支的电子交易协议的基础上,提出了一种基于电子钱包的乐观公平交易协议。通过应用加密算法的交叉验证,实现了协议的原子性,同时引入了电子钱包作为安全控制端,避免了客户的恶意透支。本文详细描述了协议的执行过程,并非形式化地证明了协议的原子性和安全性。By analysing the electronic commerce protocol based on credit, the paper proposes an optimistic fair e-commerce protocol with electronic wallets. By applying the Cross Validation for encryption algorithms, the atomicity of the electronic commerce protocol can be really achieved. Towards the e-commerce protocol based on an improved DSA signature algorithm, the paper analyzes the condition of the customers＇ vicious overdraft. The introduction of electronic wallet as the security control terminal effectively avoids the customers＇ vicious overdraft. The whole process of the protocol is elaborated. The atomicity and security of the protocol is validated informally.
