基于安全信誉机制的SET协议

SET Protocol Based on Secure Reputation Mechanism

针对安全电子支付协议不能刺激商家售后服务质量提高的弊端,文中提出了基于安全信誉机制SET支付协议的改进方案,并对该方案的安全性能进行分析。分析结果表明文中提出的改进方案不仅保持了原有SET协议的安全性,而且提高了商家对客户售后投诉的响应速度,避免了商家通过聘用托的合谋攻击问题,进一步保障了消费者的利益。

Current secure transmission protocol exhibits some deficiencies in settling dissension. By analyzing the SET protocol, some hidden troubles of SET are discovered, and thus an improved scheme based on SET protocol of secure reputation mechanism is proposed. Experiment indicates that the improved scheme raises the responsive speed to the after-sale complaint of the customer while maintains the security of the original SET protocol. This scheme could avoid the collusion attack by the merchants and further ensure the benefit of the consumers.
