| Abstract | In recent years, Wireless Sensor Networks (WSNs) and Wireless Local Area Networks (WLANs) have witnessed dramatic development due to the variety of applications and cost effectiveness in network deployment. However, we believe the wide application of both WSNs and WLANs in the future is contingent on the security of the networks. Considering that wireless nodes in both WSNs and WLANs are less powerful and more vulnerable than their wired counterparts, we focus on studying the attacks targeting on wireless nodes and their defenses in this dissertation. First, we study node destroying attack in WSNs and its defense. In search based node destroying attack we model, the attacker walks through the network using signal detecting equipment to locate active sensors, and then destroys them. To defend against such attack, we design a defense approach based on sacrificial nodes. The core principle of our defense is to trade short term local coverage for long term global coverage through the sacrificial node assisted attack notification and sensors states switching. Second, we study node penetrating attack in WSNs and its defense. In node penetrating attack, the attacker is able to penetrate a certain percentage of the nodes in the network, and access all the secret information stored in the penetrated nodes. We propose a defense methodology called network decoupling to deal with such attack, |
