摘要
提出了一种基于智能卡的匿名公平移动支付系统模型,基于该模型提出了一个可追踪匿名的脱线式数字现金协议,它使用智能卡作为分布匿名代理,实现了数字现金的动态匿名和兑零的功能[证明了匿名数字现金满足安全性和可追踪匿名性,该协议的效率高于基于盲签名和匿名代理服务器技术的协议。提出了一个关于时间敏感商品的公平移动支付方案,即使用智能卡实现交易中介功能,减少了使用时间戳和全局统一时钟的代价。业已证明该方案是公平的。
A fair and anonymous mobile payment system model utilizing smart card was proposed.An anonymous off-line digital-cash payment protocol was presented.It uses smart card as a distributed anonymity provider agent based on Schnorr signature scheme.It provides dynamic accountable anonymity and changing for digital-cash.It was proved that secure and accountable anonymity of digital-cash was guaranteed.The protocol was proved efficiency in mobile environ-ments.A protocol for fair exchange time-sensitive goods was proposed.Our approach utilizes smart card on the custo-mer’s side partly taking over the duties of the intermediary party.Besides supporting disconnected operations,our ap-proach also allows the proper handling of time-sensitive items,a feature that previous protocols lack.
