| 摘 要： | 针对已有SIP(session initiation protocol)服务支付方案的缺陷,提出了一种基于Hash链的SIP服务实时支付方案——SIPCoin。SIPCoin充分利用了Hash链高效、不可逆的良好特性,通过对SIP协议的简单扩展和一个根据标准设计的新的支付消息流程,将基于Hash链的微支付机制和SIP会话的建立、管理流程有机结合起来,可实现安全的SIP服务实时支付。分析表明,相比已有的SIP服务支付方案,SIPCoin不仅具有高效、实时和可扩展的良好性能,而且支持电子货币防伪等安全特性,可抵御SIP服务支付中常见的重放攻击和中间人攻击等。

| Abstract: | The problems with present payment schemes for SIP services are overcomed with a real-time payment scheme for SIP services based on hash chains,SIPCoin.SIPCoin takes advantage of the efficiency and irreversibleness of the hash chain to improve performance.The scheme uses a simple extension to SIP and a standard payment message flow integrated with the hash chain-based micro-payment mechanism, and the SIP session establishment and management process to realize secure real-time payments for SIP services.SIPCoi... |
