文章基于一种模块化的安全协议设计方法,定义了基本消息和基件的概念后,从研究安全协议的基件开始,将不同的基件适当复合后可得到具有特殊安全属性的组件,并运用BAN类逻辑对这些组件进行了形式化的分析。这些具有特殊安全属性的组件,在满足协议需求的同时,从底层开始保证了协议能够达到预期的安全目标,为安全协议的设计奠定了基础。 相似文献

目前,网络安全及隐私受到广泛关注。前向安全性是Günther在1989年提出的一种认证密钥协商协议( AKA)的安全属性(doi: 10.1007/3-540-46885-4_5),该性质经过30年的蓬勃发展已经成为研究领域的热点之一。该文主要分析了MZK20和VSR20两个AKA协议。首先在启发式分析的基础上,利用BAN逻辑分析了MZK20协议不具有弱前向安全性;其次利用启发式分析和Scyther工具证明了VSR20协议不具备前向安全性。最后,在分析VSR20协议设计缺陷的基础上,提出了改进方案,并在eCK模型下证明了改进后协议的安全性;并且,结合Scyther软件证明了改进VSR20协议与VSR20协议相比明显提高了安全性。 相似文献

Healthcare is one of the major applications of wireless systems that possess crucial issues. Specifically developing countries require a low cost and reliable network with efficient protocols. The most challenging concern of Body Area Network (BAN) is heterogeneity, which requires fairness with reliability among all the network nodes. Solutions proposed for these networks either do not provide fair packet transmission or consume high energy and introduce delays. In this paper, we propose a cross layer protocol for healthcare applications meeting the requirements and challenges of the heterogeneous BAN. The protocol is also feasible for developing countries as it can be implemented over existing wireless infrastructure and provides high network reliability with energy efficiency through cooperation and adaptability. Results show that the proposed scheme improves reliability, throughput, Packet Delivery Ratio (PDR), and energy consumption for scalable and mobile networks over conventional BAN protocols. 相似文献

Based on combined public key (CPK), a novel universal authentication protocol which conforms extensible authentication protocol (EAP) specification in heterogeneous networks was presented, so called EAP-CPK. Subsequently, detailed authentication process and related delay analysis of EAP-CPK in the 3rd Generation Partnership Project wireless local area network (3GPP-WLAN) interworking network were also given. In this paper, parameters from client and server related with mutual authentication process are classified systematically, and detailed verification process by using BurrowsAbadiNeedham89 (BAN) logic analysis is proposed. Security analysis results show that the proposed protocol is secure, and it not only can prevent man-in-the-middle attack and replay attack, but also can make lower system cost. 相似文献
