Wireless Sensor Networks in ThreeTier Security Scheme Using Polynomial Bool Based Algorithms

D. Jayachitra, N. Nithya

Abstract :

Wireless Sensor Networks (WSNs) are simple to deploy and allow stretchy installation which has to enable them to be used for numerous applications. Due to these properties, they face distinct information security threats. Security for WSNs is very much needed, because of its sensitive information transmission. The sensor network is exposed to many types of attacks because they are deployed in public background. So it is necessary to secure sensor networks, this can be achieved by introducing authentication and pairwise key establishment mechanisms to sensor nodes. In the proposed system, some nodes are select as a stationary access node to provide authentication access between mobile sinks and sensor nodes. The key distribution mechanism uses two types of key pools: the mobile key pool and the static key pool, the keys in the mobile key pool are shared between mobile sinks and SANs the keys in the static key pool are shared between SANs and Static sensor nodes. This paper proposes a general three–tier security framework for authentication and pairwise key establishment between mobile sinks and sensor nodes. This paper algorithm the polynomial pool–based key pre–distribution scheme considerably improve network resilience to mobile sink replication attack compares to the single polynomial pool–based key predistribution approach.
