Abstract: In Wireless Sensor Networks (WSN), the secure localization is extremely significant for enhancing the accuracy of localization and robustness against security threats. Also most the existing literature research lacks the security approach towards localization mechanism which may affect the secure communication of the data. Hence, in this study, researchers propose a secure authentication technique for localization in WSN. Initially the position of sensor nodes is estimated using proximity distance map computation. The anchor nodes then generate a location based key pair for each sensor node. This ensures that the attackers cannot exploit the positions and location based keys of compromised nodes. Then, the mutual authentication of neighbour nodes is performed based on location information. By simulation results we show that the proposed approach offers improved security in WSN.
