A BLOCKCHAIN BASED SECURITY MODEL FOR IOT ECOSYSTEM

The use of IoT devices has been increasing exponentially with time and this raises serious concerns for the overall protection of the huge IoT Network's and the database's associated with it. While there are many proposed approaches to deal with different security related aspects in IoT, one of the potential solutions to such issues is Blockchain. Blockchain is a rapidly emerging technology and is used in various fields. Blockchain technology has features like decentralisation and immutability which guarantees security. A blockchain based security model has been proposed in this paper for securing IoT devices from various security threats. Finally, proposed approach and its implementation using blockchain to secure IoT Ecosystem is discussed to make IoT ecosystem more secure.
