可直接花费余额的电子支票系统

A Fair Electronic Check Systems with Reusable Refund

首次将公平性引入电子支票中,描述了公平电子支票的模型,设计了一个可直接花费余额的公平电子支票系统.系统使用基于RSA的部分盲签名技术实现了余额的直接花费,使用一个被动的TTP进行匿名撤销.

The fairness is introduced to electronic check system for the first time,and the model of fair electronic check is discussed. A fair electronic check system with reusable refund is presented. In the system, the refund is reusable thanks to the RSA-based partially blind signature,and the anonymity revocation is achieved by employing a passive TTP short for trust third party.The system is efficient and meets all basic security requirements.
