【摘要】 移动自组网是由移动节点自组织形成的网络,由于其动态拓扑、无线通信的特点,容易遭受各种安全威胁。移动自组网入侵检测是安全研究中最核心的技术之一。对现有的入侵检测体系结构进行了讨论,同时分析了各自的优点和缺点,接着较详细地介绍了各种检测方法,并进行了综合比较。最后指出移动自组网入侵检测研究今后发展的趋势。更多还原

【Abstract】 In resent years,mobile ad hoc networks are a new emerging field with its potential applications in extremely unpredictable and dynamic environments.However,it is particularly vulnerable due to its features of open medium,dynamic changing topology,coo-perative routing algorithms.Intrusion detection is one of the most active and important network security technologies.An overview of basic issues on intrusion detection in mobile Ad Hoc networks is shown,which is involved with two main aspects of intrusion detection,including Intrusion detection system(IDS) architecture and intrusion detection methods.Firstly three kinds of IDS architectures are given,and their merits or shortcomings are discussed in detail.Then current intrusion detection models are analyzed.Finally some future promising directions are presented.更多还原
