AB  - 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.
