无线自组织网络中DDoS攻击源追踪技术研究综述

SURVEY OF RESEARCHES ON TRACEBACK TECHNIQUES AGAINST DDOS ATTACKS IN WIRELESS AD HOC NETWORKS

无线自组织网络因其自身特点比传统的有线网络更容易遭受拒绝服务攻击。攻击源追踪技术是抵御分布式拒绝服务(DDoS)的一种重要方法,这种技术得到了研究者的广泛关注,成为了一个热点研究问题。但是,目前无线自组织网络中大部分的研究工作都是Internet已有方法的移植,有很大的局限性。将目前无线自组织网络中攻击源追踪技术的研究现状进行分类和介绍,并分析了自组织网络中追踪面临的挑战以及未来的研究发展方向。

Wireless Ad hoe network is more vulnerable to DDoS attack than wired network for its Characteristics. IP traeeback is one of the important techniques to defend DDoS attack, which has attracted wide attention and becomes the focus of the research. However, most of the researches in regard to wireless Ad hoc network are based on transplanting the existing Internet IP traceback approaches, and have great limitation. In this paper we classify and introduce current researching status of IP traceback technologies in wireless Ad hoc network, analyse the challenges the traceback encountered in Ad hoc network, and point out the development direction of future researches.
