To prevent e-cash from double-spending and unlimited increase in the records of databases, an improved offline e-cash system based on elliptic curve cryptography was proposed.
为防止电子现金重复花费和数据库记录无限制的膨胀问题,改进了现有的利用椭圆曲线密码系统构造的离线电子现金系统。
In this paper, we introduce a notion called restrictive blind group signature, then we construct a fair off-line e-cash system in the multiple bank model with both user and bank anonymity control.
本文提出一个新的称为限制性群盲签名的概念,并且指出了如何利用限制性群盲签名来构造多个银行参与发行的、公正的电子现金系统。
Applying our partially restrictive blind signature protocol, the thesis proposes an efficient off-line e-cash system based on discrete logarithm and representation problem.
运用我们提出的部分受限盲签名协议,我们提出了一个高效的基于离散对数及表示问题的离线电子现金系统。
