Abstract: Fraud and low-efficiency prevent micro-payment schemes based on PayWord from being utilized.Considering social reality,the improved micro-payment scheme based on symmetric key cryptography is presented,and then security of the session key is proved with BAN logic.The particular analysis about its computing complexity and operating efficiency compared with other schemes is given.Analysis shows that there are many specialties such as lightweight computation in the scheme,and the goals such as anti-consumer-overdraft and anti-merchant-fraud are achieved with efficiency.

摘要: 欺诈及低效等问题阻碍了基于PayWord的微支付系统的应用。从现实状况出发,提出基于对称密码系统的改进的微支付方案,给出了会话密钥安全目标的BAN逻辑证明。对比其他方案,对协议的计算复杂度及运行效率进行了详细分析。分析表明,新方案具备计算量低等特性,高效地达到了杜绝用户透支及商家欺诈等目标。
