摘要
提出了一个基于椭圆曲线代理签名的多银行电子现金系统。通过分析表明,新方案可方便取消发币银行的发币能力,并克服了现有的基于群签名的多银行电子现金系统的群成员删除难、群成员合伙攻击等问题。
An electronic cash system with multiple banks based on proxy signature from elliptic curve was proposed. The analysis showed that the signing capability of the issuing bank can be easily canceled in the electronic cash system and it avoids some problems such as member deletion, coalition attacks in the existing e-cash system with multiple banks based on group signature scheme.
