Resilience Against Node Capture Attack using Asymmetric Matrices in Key Predistribution Scheme in Wireless Sensor Networks
Wireless Sensor Networks (WSN) usually consists of a large number of tiny sensors with limited computation capability, memory space and power resource. WSN’s are extremely vulnerable against any kind of internal or external attacks, due to several factors such as resource constrained nodes and lack of tamperresistant packages. To achieve security in Wireless Sensor Networks, it is important to ...
متن کاملStrongly Resilient Non-Interactive Key Predistribution For Hierarchical Networks
Key establishment is the basic necessary tool in the network security, by which pairs in the network can establish shared keys for protecting their pairwise communications. There have been some key agreement or predistribution schemes with the property that the key can be established without the interaction ([3], [4], [19]). Recently the hierarchical cryptography and the key management for hier...
متن کاملProbabilistic Analysis of Covering and Compromise in Node Capture Attacks
In this technical report, we analyze wireless sensor networks (WSN) under node capture and cloning attacks. Assuming that WSNs use symmetric keys, with key assignment based on a random key predistribution scheme, we provide extensive probabilistic analysis of WSNs under the attack. We define and characterize the following parameters: the number of nodes an adversary needs to capture in order to...
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 کاملA New Key-Predistribution Scheme for Highly Mobile Sensor Networks
In this paper, we propose a new deterministic key predistribution scheme for secure communication in wireless sensor networks. Our scheme provides better trade-off among scalability, computation overhead, connectivity and resilience against node captures than existing key predistribution schemes, particularly in situations where the nodes in the network are highly mobile.
