Resilience Against Node Capture Attack using Asymmetric Matrices in Key Predistribution Scheme in Wireless Sensor Networks
Journal Title: International Journal on Computer Science and Engineering - Year 2011, Vol 3, Issue 10
Abstract
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 encrypt messages sent among sensor nodes. In this paper, we propose a scheme called Modified Bloom’s Scheme (MBS) that uses asymmetric matrices of keys in place of symmetric matrices in order to establish secret keys between node pairs.The network resilience against node capture attack is improved using the proposed scheme.
