摘要: 提出一种新的电子现金方案,利用基于身份的加密技术,实现能保障收款方如期收款的延时付款功能。设计电子现金方案安全模型,该模型将银行视为非可信方,使银行行为可以被公众检验。分析结果表明,新方案在该模型下具有较高安全性。

关键词: 电子现金, 强安全模型, 基于身份的加密

Abstract: This paper proposes a new e-cash scheme, which supports delayed payment. The new function is implemented by ID-based encryption technology. It designs an e-cash secure model, which regards bank as an untrust party. In this model, bank’s behaviors can be inspected, and the new scheme is secure.

Key words: e-cash, strong secure model, ID-based encryption
