摘要:

基于双线性对,并采用动态累加器技术,提出了一种基于身份的简短关联环签名方案(SLRS-BP)。以此为基础,设计了1个可撤销匿名性的公平电子现金协议(EC-LR)。SLRS-BP签名具有简短性及环签名的自发性,使得EC-LR适合银行系统电子货币用户数量多、动态变化的特点,且避免了基于群签名的电子现金协议所存在的成员撤销等问题。

Abstract:

Based on bilinear pairings and dynamic accumulators, a new ID-based linkable ring signature scheme (SLRS-BP) was presented. According to SLRS-BP, a fair e-cash protocol (EC-LR) with revocable anonymity was given. By virtue of constant-size signature of SLRS-BP and the spontaneity of ring signatures, the EC-LR will show good for the bank systems which have large numbers of dynamically changed users. In addition, EC-LR can avoid the member revocation problem of e-cash protocols based on group signatures.

Key words: linkable ring signature, bilinear pairings, dynamic accumulators, revocable anonymity, fair e-cash
