基于门限群签名的电子支票系统的设计和研究

金融服务技术联盟（FSTC）提出的电子支票解决方案作为未来电子支票一个潜在的标准，系统地对电子支票的支付模式、系统安全、系统架构等进行了研究和探讨，能够有效地解决大多数情况下的支付问题。在FSTC电子支票标准（草案）基础上，提出了一种基于门限群签名的新型电子支票解决方案,从而有效地解决了企业、政府等机构在电子支票支付应用中所面临的安全性、可靠性、灵活性等问题；同时也从技术安全和策略安全两个层面对整个系统的安全性进行了分析。

Design and Research of Electronic Check System Based Threshold Group Signature

The scheme of electronic check put forward by Financial Services Technology Consortium (FSTC) will be a potential standard in future. It has generally studied and discussed the mode of payment, the safety and the composition of the system, and has an effect on solving the problem of payments taken place under many conditions. Based on the electronic check draft advanced by FSTC and threshold group signature, this paper presents a new electronic check system. In new system, these particular problems such as security, reliability and facility and so on, which are faced with in the enterprises and go-vernments agents' transactions, have been settled efficiently. Meanwhile, the article also analyzes the system security from strategy safety and technique safety aspects.
