摘要
提出一个多银行的、公正、可分、高效的电子现金系统。系统中使用限制性群盲签名,中央银行作为群管理者,各发币银行是群成员,使用单一的群公钥,任何人都能够验证电子现金的有效性,并将"可分性"解决技术和概率验证技术整合在其中。
This paper uses restrictive blind group signature to construct a system of fair ecash issued by multiple banks. In this system, central bank is a group manager and issuing banks are group members. Everyone can validate an ecash by using a unique group public key. Divisible technique and probabilistic audit scheme are used together to make this system into a multiplebank, fair, divisible, and efficient ecash system
