An Improved Authentication Scheme for Wireless Sensor Network Using User Biometrics

Sensors are tiny devices deployed in an unsupervised environment. These devices monitor the readings, process them, and transmit them to the predefined destination. The internet has also availed the users to query the sensors and get the values directly. Users are to register themselves with the gateway node. After registration, they increase flexibility to query the sensors. The sensors are to authenticate the users for their legitimacy before dispatching the requested information. The proposal increases security by minimizing the replay attacks and enhance reliability in sensor-user communication. The proposed work hikes reliability as well as conserves energy substantially. Also, it minimizes replay attacks that are vulnerable in WSN.
