Abstract: The use of Wireless Sensor Networks (WSN) in the field of military, battlefield, healthcare applications etc has seen a plethora of growth towards variety of sensory devices. Irrespective of different locations, the sensor nodes has to do its task. Hence, the dynamic wireless sensor networks should ensure better quality of sensor nodes that covers wider network area and additional services in relative to static WSNs systems. By doing so, it requires secure data communication among the sensor nodes in wireless environment. Key Management is the recent security concept enabled to provide secure communication between sender and receiver nodes. In this paper, we have proposed efficient key updates systems between the nodes. In any scenario, the nodes may join or leaves the network environment which facilitates to initiate a secret key between intended sender and intended receiver. A certificate less key secrecy system is designed for secure communication in wireless links. By designing so, we have addressed the issues like node authentication, data confidentiality and data integrity. Experimental analyses have shown the effectiveness of proposed system.
Keywords: Wireless Sensor Networks, Dynamic Networks, Sensor Nodes, Sensory Devices, Key Management, Key Updates And Node Authentication.
