Abstract

Abstract: An E-cash system with multiple banks based on restrictive proxy blind signature is proposed. In the E-cash system, the withdrawal date and the expiry date prescribed by the bank are embedded in the withdrawn E-cash. The bank only needs to keep all used and undue E-cash in its database to trace the double-spender, thus it reduces the storage level and improve the querying efficiency of the bank to double-spending

Key words: E-cash, blind signature, restrictive proxy blind signature, signature of knowledge

摘要： 基于限制性代理盲签名, 提出了一种新的多银行电子现金系统。在用户提取的电子现金中，嵌入了银行规定的该电子现金的有效期，银行只需保留已经使用过的且还未过期的电子现金，这就大大减少了银行的存储量，提高了银行的效率
