对一种电子支付协议的改进 总被引:1,自引:0,他引:1
随着电子商务在全球的迅猛发展,电子商务的安全问题日益受到人们的关注。安全的电子商务协议是确保电子商务活动可靠开展的基础,其中不可否认性和公平性则是电子商务协议的两个重要安全需求。介绍了Bolignano电子支付协议,对其不可否认性和公平性进行了分析,发现了协议在公平性方面存在不足,并通过引入ftp传送的思想,对协议进行了改进。最后本文通过严格的协议形式化分析,证明了改进后的协议满足不可否认性和公平性。 相似文献

网络支付协议的形式化安全需求及验证逻辑 总被引:2,自引:0,他引:2
从整个网络支付协议的安全角度出发,提出网络支付协议的多层安全需求模型,包括以认证和密钥分配为基础的基层需求、网络支付协议固有的中层需求(包括保密性、原子性、公平性、完整性、匿名性、不可否认性、可追究性等)、以及面向具体应用的高层需求。基于一阶逻辑和时序逻辑,提出一种适合描述网络支付协议的形式化安全需求的逻辑,描述了该逻辑的语法结构和推理规则,并用该安全需求逻辑对网络支付协议的多层安全需求进行了形式化描述。最后,以SET协议为例进行需求验证。 相似文献

基于ATL的公平电子商务协议形式化分析 总被引:1,自引:0,他引:1
针对传统时序逻辑LTL,CTL及CTL*等把协议看成封闭系统进行分析的缺点,Kremer博士(2003)提出用一种基于博弈的ATL(Alternating-time Temporal Logic)方法分析公平电子商务协议并对几个典型的协议进行了公平性等方面的形式化分析。本文讨论了ATL逻辑及其在电子商务协议形式化分析中的应用,进一步扩展了Kremer博士的方法,使之在考虑公平性等特性的同时能够分析协议的安全性。最后本文用新方法对Zhou等人(1999)提出的 ZDB协议进行了严格的形式化分析,结果发现该协议在非保密通道下存在两个可能的攻击:保密信息泄露和重放攻击。 相似文献

公平的移动小额支付协议 总被引:1,自引:0,他引:1
为了实现具有完全公平性和非单元支付功能的小额支付协议,该文首先提出了双PayWord链(DPWC)的概念和非单元支付的实现机制。利用DPWC,并基于数据业务管理平台(DSMP)提出了一种新的公平的移动小额支付协议(FMMP)。该协议由注册、支付、仲裁、结算和注销5个子协议组成。分析结果表明,该协议能提供支付的完全公平性和非单元支付功能,并且具有安全、高效和不可否认的特点。 相似文献

During the past few years, many near‐field communication (NFC) mobile payment protocols have been widely used and received more and more attentions. This could be an essential factor for the growth of the world economy and leads to the improvement of the quality of life for human beings. The NFC mobile payment is one prominent approach in allowing m‐commerce to conduct a sales transaction. However, fair exchange and information security are significant concerns in creating trust among the parties participating in the transaction. Many NFC mobile payment protocols have been introduced by researchers. But, most of them still lack some crucial properties of information security and fair exchange, and this can be an obstacle to their uses. In this article, we propose an NFC mobile payment protocol that possesses comprehensive properties of both information security and fair exchange for sales transaction processing. The protocol employs both symmetric and asymmetric encryptions, hash function, and the technique of offline session key generation, in order to improve the security while maintaining the lightweight property. The fairness analysis shows that the proposed protocol is more competent and effective than others. It can resolve any dispute in case one party misbehaves. Finally, the proposed protocol's security has been successfully verified using both Burrows, Abadi and Needham (BAN logic) and the Scyther tool. 相似文献

The widely use of networks and e-commerce has brought great convenience to our daily life. The basis of normal e-commerce transaction between the seller and customers is the secure e-commerce protocols which must also include the two important properties, namely, non-repudiation and fairness, in addition to those basic properties such as secrecy, security, authentication and integrity[1]. So there are special and higher demands of the performance and function of the e-commerce protocol. To att… 相似文献

Using the idea of Payword, the new concept of master-slave payword chain (MSPC) is proposed in this article. MSPC consists of one master payword chain and one slave payword chain. On the basis of MSPC, a new micropayment protocol called discrete micropayment protocol (DMP), is presented in this article. DMP consists of three sub-protocols: registration, payment, and settlement. Both part fairness and non-unit-wise payment can be provided by DMP. 相似文献

移动计算网络环境中的认证与支付研究 总被引:4,自引:0,他引:4
该文针对移动计算网络的技术特点设计了一个用于移动用户与收费信息服务网络相互认证和用户进行电子支付的方案,该方案的新颖之处在于把小额支付方案融入认证协议当中,方案不仅在公共参数的存储空间需求和用户端计算负荷上是适当的,而且可以保护用户不被错误收费,同时提供服务者防止用户抵赖的合法证据。该方案基于一个全局的公钥基础设施,适合于未来的基于第三代移动通信系统的网络计算环境。 相似文献
