摘要
本文基于Schnorr不可抵赖签名算法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;证明数字现金是安全的且满足可追究匿名性;协议的效率比基于盲签名和匿名代理服务器的协议高,可以应用于移动环境下的匿名支付。
An off-line anonymous digital-cash payment protocol is presented in this paper. It uses the smart card as a distributed anonymous provider agent based on the Schnorr signature scheme. It provides dynamic accountable anonymity and changing for digital cash. Digital cash is proved secure, and accountable anonymity is guaranteed. The protocol is proved efficient in mobile environments.
