Integrating a Secured Access Control Policy on Wireless Sensor Networks

A new generation of high-scale sensor networks suitable for a range of enterprise application is thriving by current advancements in electronics. In this work, we proposed a mechanism for securing data generation in a wireless sensor network. Wireless sensor networks (WSNs) are networks that provide a virtual layer where the information about the physical world can be accessed by any computational system. WSNs are made up of nodes from a few to several hundreds or even thousands where each node is connected to one or several sensors. The data generated can be easily compromised by an attacker if adequate security measures are not taken. Access and Authorization to the sensory data should be given to authorized users with the right attributes if data integrity and authentication (in a fine-grained manner) should be maintained. The increased security of the proposed system is achieved by the increased in the key size above the existing system. Achieving secure fine-grained access control policy over security challenges like sensor node compromise, accessibility of users to sensor nodes, data privacy, and protection of components on WSNs need a secure system that can precisely specify what the users can access, where and when to access any data at a particular time in the network.
