Secure building automation system using Tesla protocol

Wireless broadcast communication systems are continuously facing many threats in terms of various security attacks on the network. Broadcast communication has well known advantages in large scale networks such as building automation system, home automation and more. The need for verification and authentication in the broadcast communication had motivated us to develop a unique security algorithm for a robust authentication mechanism. This project proposes a unique methodology that combines the advantage of the gradient based routing and cryptography in a network. For implementation of the proposed algorithm, an example of building automation has been used. Principles of TESLA protocol were considered, and modified to craft a novel approach that provides a highly secure broadcast authentication mechanism in the building automation system. Implementation and results produced during the development phase of the project affirms the effectiveness of the proposed algorithm.
