摘要
i KP协议是 IBM公司提出的一组公开的基于信用卡的安全电子支付协议 ,该文则在 i KP协议基础上提出了一组有效的公平电子商务协议 .该协议在 i KP协议中有机地融入了信息商品的传输 ,使得 i KP协议能够用于信息商品与支付信息的公平交换 ,并且引入了对交易的时延控制机制 ,避免了转发中可能的迟发或不发 ;所提出的协议仅增加了尽可能少的、必须的密码运算和消息 .最后 ,文中对协议的安全性。
The i KP is a secure credit card based payment protocols which is designed and opened by IBM. A set of fair electronic commerce protocols based on i KP is given in the paper. The presented protocols implements the fair exchange of information goods for payment, and the mechanisms used to control transaction timeout are introduced to avoid the possible delay in the transfer of messages; the added cryptographic operations and messages are necessary and as possible as least in the proposed protocols. Finally, the security, fairness and effectiveness of the protocols are discussed.
