An Efficient Security Way of Authentication and Pair wise Key Distribution with Mobile Sinks in Wireless Sensor Networks
Journal Title: International Journal of Modern Engineering Research (IJMER) - Year 2013, Vol 3, Issue 4
Abstract
Wireless sensor networks (WSN) are the emerging application in many industrial and missile sector. Mobile sinks (MSs) are vital in many wireless sensor network applications for efficient data accumulation, localized sensor reprogramming, and for distinguishing and revoking compromised sensors. However, in sensor networks that make use of the existing key pre-distribution schemes for pairwise key establishment and authentication between sensor nodes and mobile sinks, the employment of mobile sinks for data collection elevates a new security challenge: in the basic probabilistic and q-composite key predistribution schemes, an attacker can easily obtain a large number of keys by capturing a small fraction of nodes, and hence, can gain control of the network by deploying a replicated mobile sink preloaded with some compromised keys. The proposed work, three-tier framework permits the use of any pairwise key pre-distribution scheme as its basic component. The new framework requires two separate key pools, one for the mobile sink to access the network, and one for pairwise key establishment between the sensors. To further reduce the damages caused by stationary access node replication attacks, the authentication mechanism between the sensor and the stationary access node is strengthened in the proposed work. This framework has higher network resilience to a mobile sink replication attack as compared to the polynomial pool-based scheme.
