| 摘 要： | 椭圆曲线密码体制以其特有的优越性被广泛用于数据加密，数字签名，同样也可用来构建电子现金系统。因此设计出了一个基于椭圆曲线离散对数的可分电子现金协议系统。此系统是基于椭圆曲线离散对数表示问题的。其安全性是基于椭圆曲线离散对数的安全性。系统采用限制性盲签名，因此满足公平匿名性。

| Abstract: | Elliptic curve cryptosystems are used for data encrypt and figure sign extensively with their peculiar superiority, and they can be used for structuring the electronic cash system too, so a separable electronic cash system is designed based on elliptic curve dispersed logarithm. The system is based on expression question of elliptic curve dispersed number. Its security is based on the security of elliptic curve dispersed logarithm. The system uses limited blind signature so it satifies fairly and anonymously. |
