随着Ad hoc网络的广泛应用,其固有的特性和安全漏洞带来了极大的安全隐患,其中虫洞攻击是Ad Hoc网络难以解决的攻击之一,本文首先阐述了虫洞攻击的原理,然后将虫洞攻击的2种模式进行了分析。后面介绍了现在已提出的检测虫洞攻击的多种方法,本文第3部分对这些方法的一些功能和局限(同时检测2种模式的虫洞攻击、定位恶意节点、需要额外的硬件设备等)进行了比较,对在什么环境使用什么检测方法提出观点,最后作者提出了如何解决虫洞攻击的思路。
With the wide application of Ad hoc networks, its inherent characteristics and security vulnerabilities have brought great security risks. Among them, wormhole attacks are one of the most difficult attacks in Ad Hoc networks. This paper firstly expounds the principle of wormhole attacks, Then the two modes of wormhole attack were analyzed. In the following sections, we present a number of ways to detect wormhole attacks. The third part of this article discusses some of the functions and limitations of these methods (detecting wormhole attacks in both modes, locating malicious nodes, and requiring additional hardware) Made a comparison on what environment to use what testing methods put forward their views, the last author put forward how to solve the worm attack ideas.
