【摘要】 通过对现有微支付协议的分析研究,指出了它们在安全方面存在的问题,提出了一种新的基于混沌双Hash链的移动微支付协议。该协议主要是针对价值较低的网络信息服务收费的需要,利用类混沌系统迭代过程的单向性构造出双支付字链,通过双支付字链中的一个链确定的支付字对商家收费,而通过另一个链确定的支付字对用户收费。该协议具有匿名性、用户订购信息机密性,并能够提供部分公平性。分析表明,该协议安全性更高,并且执行效率更快,适用于交易金额微小的移动微支付业务。更多还原

【Abstract】 The current micropayment protocols are analyzed and it is found that there exist security problems.A new mobile micropayment protocol based on chaotic dual Hash chains is proposed.This protocol is mainly developed for the demand of lower value network information service charge.It utilizes the one way character of the interaction process of Hénon-like chaotic system to construct two Payword chains.One Payword chain is used to charge merchants and the other Payword chain is used to charge users.The protocol possesses the character of anonymity that the information ordered by users is of confidentiality and it provides partial fairness character.Analysis demonstrates that the protocol has higher security and faster operation efficiency,and it is suitable for the micropayment transactions with very small trade amount and only partial fairness requirement.更多还原
