In Wireless Sensor Networks (WSNs), the sensor nodes transmit critical information over the network. Therefore security services such as authentication and pair wise key establishment between sensor nodes and mobile sinks are important. However, the problem of authentication and pair wise key establishment in sensor networks with mobile sinks is still a critical problem in the face of mobile sink replication attacks. In the basic probabilistic and q-composite key pre distribution schemes, an attacker can easily obtain a large number of keys by capturing a small fraction of the network sensor nodes.
