Client Puzzle Approach for Securing Aggregated Data in Wireless Sensor Network

Acquiring security in the event of aggregated data in wireless sensor network is challenging task because of its limitations in terms of calculation, resources, battery power, transmission capacities and so forth. Networks are liable to be made of many tiny sensor nodes, working autonomously without access to renewable energy resource. As wireless sensor networks edge nearer towards broad deployment, security issues become a focal concern. Hence to preserve energy aggregation technique is applied. To mitigate Denial of Service attack and to secure aggregated data one of the client puzzle approach, RSA authentication technique is used.
