Abstract: Wireless Sensor networks (WSNs) are easy to deploy and allow flexible installations which have enabled 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. Sensor networks are vulnerable to many types of attacks because they are deployed in public environment. So it is necessary to secure sensor networks, this can be achieved by introducing authentication and pair wise key establishment mechanisms to sensor nodes. In the proposed system some nodes in WSN are selected as stationary access nodes (SANs) to provide authentication access point between mobile sinks and static 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.
Keywords: Mobile sinks, Stationary access node, Pair-wise key distribution, Pre-distribution, Replication attack.
