Distributed Detection of Node Capture Attacks in Wireless Sensor Networks
Wireless sensor networks are vulnerable to node capture attacks because sensor nodes are usually deployed in unattended manner. Once attacker captures sensor nodes, he can compromise them and launch various types of attacks with those compromised nodes. Therefore, node capture attacks are hazardous and should be detected as soon as possible to reduce the harm incurred by them. To meet this need...
متن کاملA Secure Routing Algorithm for Underwater Wireless Sensor Networks
Recently, underwater Wireless Sensor Networks (UWSNs) attracted the interest of many researchers and the past three decades have held the rapid progress of underwater acoustic communication. One of the major problems in UWSNs is how to transfer data from the mobile node to the base stations and choosing the optimized route for data transmission. Secure routing in UWSNs is necessary for packet d...
متن کاملMitigating Node Capture Attack in Random Key Distribution Schemes through Key Deletion
Random Key Distribution (RKD) schemes have been widely accepted to enable low-cost secure communications in Wireless Sensor Networks (WSNs). However, efficiency of secure link establishment comes with the risk of compromised communications between benign nodes by adversaries who physically capture sensor nodes. The challenge is to enhance resilience of WSN against node capture, while maintainin...
متن کاملModeling adaptive node capture attacks in multi-hop wireless networks
We investigate the problem of modeling node capture attacks in heterogeneous wireless ad hoc and mesh networks. Classical adversarial models such as the Dolev–Yao model are known to be unsuitable for describing node capture attacks. By defining the amortized initialization overhead cost as well as the cost of capturing a node, we show that finding the node capture attack yielding the minimum co...
متن کاملImprovement of Dependability against Node Capture Attacks for Wireless Sensor Networks
A Wireless Sensor Network has sensor nodes which have limited computational power and memory size. Due to the nature of the network, the data is vulnerable to attacks. Thus, maintaining confidentiality is an important issue. To compensate for this problem, there are many countermeasures which utilize common or public key cryptosystems that have been proposed. However, these methods have problem...
