Authentication and Secure Data Access Privacy in Wireless Sensor Networks

Abstract

An authentication and secure data access privacy in wireless sensor network enforces strict access control so that the sensed data will not be obtained by unauthorized users. A secure data access privacy involves three participants namely, the network owner, all sensor nodes and the network users. The users who want to access the data firstly register to the network owner. A network user signs a query command and then sends the signed query command to the sensor nodes. Users purchase tokens from the network owner whereby to query data from sensor nodes which will reply only after validating the tokens. The signature can be verified by its recipient as coming from someone authorized without exposing the actual signer. It ensures that only authorized users can gain access to read data from the nodes. The paper investigates the security related issues and challenges in wireless sensor networks to identify malicious activities by using a low power FPGA
