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。
Aiming at the defect that the secure electronic payment protocol can not stimulate the improvement of the quality of after-sales service of merchants, an improved scheme of SET payment protocol based on secure reputation mechanism is proposed in this paper, and the security performance of the scheme is analyzed. The analysis results show that the improved scheme proposed in this paper not only maintains the security of the original SET protocol, but also improves the response rate of merchants to customers’ complaints after sale and avoids the collusion of merchants through the hiring of consultants to further protect the interests of consumers.
