一个公平的离线电子现金方案

A Fair Offline E-cash Scheme

基于双线性映射的群签名,设计了一个新的离线电子现金方案实现了公平性。该方案结构简单,可在椭圆曲线上实现,而且没采用传统的盲签名。该方案具有较高的安全性和效率以及无陷门的密码性质。

Based on group signature scheme from bilinear pairings, a new offiine fair cash scheme is presented, Because of setting up on the elliptic curve group and without using blind signature scheme, this scheme has many properties such as having simple structure, security, efficiency, trapdoor-free and so on.
