摘　　要：为了解决网上金融交易实时清算的快速确认问题,分析了典型的交易过程及安全特性,并基于椭圆曲线签名原理,提出了一种基于双线性映射的清算确认框架协议,使得对交易结果的确认可以递进进行,并在最终清算时一次完成,有效地实现了不可否认性和证据留存,避免了复杂的PKI体系和两两确认的繁琐过程,使真正的直通式处理和在线清算成为可能.In order to find a way of fast confirmation for the real time clearance of online financial trading, this paper analyzes the typical online trading process and the security characteristics. Based on the principle of elliptic curves signing, a kind of clear confirmation scheme is proposed, which can confirm the trading result step by step, and finish it once a time at the final clear. This scheme can avoid the complicated PKI system and the one by one confirm process, realize the non-reputation efficiently, keep the proof of signing easily, and make straight through process and online clear and possible.
