Abstract: The existing security mechanisms of Wireless Sensor Networks (WSNs) authenticate communication between sensor nodes and mobile sinks. However key predistribution is a problem. Moreover the usage of mobile sinks for data collection also throws new security challenges. When one or more nodes are compromised, an attacker can collect large number of security keys. With the keys stolen an attacker can replicate a mobile sink and collect sensitive data illegally. Many schemes came into existence for secure communications in WSN. However, three β tier security scheme proposed by Rasheed and Mahapatra uses two key pools. One pool is for mobile sink and the other pool for pair wise key establishment between sensors. It also has mechanisms between access node and sensor node to avoid node replication attacks. In this paper we implemented this three tier security scheme. NS2 simulations revealed that the security framework is robust to node and sink replication attacks.
