一個公平的離線電子現(xiàn)金方案
A Fair Offline E-cash Scheme
-
摘要: 基于雙線性映射的群簽名,設(shè)計了一個新的離線電子現(xiàn)金方案實現(xiàn)了公平性。該方案結(jié)構(gòu)簡單,可在橢圓曲線上實現(xiàn),而且沒采用傳統(tǒng)的盲簽名。該方案具有較高的安全性和效率以及無陷門的密碼性質(zhì)。

Abstract: Based on group signature scheme from bilinear pairings, a new offline 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. -
