Abstract

Storage nodes play a vital role in wireless sensor networks for carrying out the storage activity of data sent by the sensor node once after capturing the details of the environment and in turn to answer the sensor data related query to the network owner. Because of the less storage capacity on the sensor node, storage node takes the whole responsibility for pre-processing the data as well as to respond to queries returned by the owner. Duplicate sensor/storage node imposes a major threat to the wireless sensor networks. The proposed approach focuses on carrying out the effective techniques for data transfer by using Elliptic Curve Encryption for encrypting the image captured from the environment and also to transmit the encrypted critical text data from source to destination, aggregate Signature to validate the sender of the message for data verification, stenography to hide the encrypted content within an image. The proposed ideas are well suited for transferring the details secure in WSN.

Keywords: ECC, Steganography, Aggregate Signature, Wireless Sensor Networks (WSN), Reliability
