Protecting Privacy Secure Mechanism for Data Reporting In Wireless Sensor Networks

V V.Rithun, C.Senthil Kumar

Wireless sensor networking is an emerging technology, which potentially supports many emerging applications for both civilian and military purpose. Node compromise is the major and unique security issues in sensor network. These compromised nodes could report false sensed results and degrade the reliability of the whole network. The secure network protocol of motesec aware only provide security against DoS attack with AES and to detect the replay and jamming attacks based on synchronized incremental counter approach. But the false report injection attacks will not be detected in motesec aware. The false report injection is one of the critical threats in wireless sensor network. Sometimes it may destroy the whole network. Filter the false report injection attacks and to prevent dos attacks dynamic en-route filtering scheme is used. The scheme each node has a hash chain of authentication keys used to endorse reports mean while a legitimate report should be authenticated by a certain number of nodes. Finally we prove our scheme efficient than existing work in terms of energy consumption and communication overhead also provide security by early detection of false reports.
