With recent advancements in the Internet of things, challenges to secure devices and data related to devices have increased. Adversaries using different threats manage to clone/hack/tamper devices by hacking credentials stored in centralised databases. In this work, a decentralised approach using blockchain is proposed to check the authenticity of the device/user trying to access the services of the service provider network. The proposed method uses public and private blockchain networks and Physical Unclonable Function (PUF) to authenticate the device/user and to store their credentials. The decentralised application runs on Hyperledger Fabric, an open-source platform for building blockchain networks. The proposed protocol is tested and implemented in the physical testbed containing Raspberry Pi and Arduino Mega's.
