A PUF-Based Secure Communication Protocol for IoT

What is it about?

In this paper, we have proposed a secure lightweight authentication, key exchange and message exchange protocol based on physically unclonable functions and identity based encryption for Internet-of-Things framework.

Why is it important?

Security features are of paramount importance for IoT, and implementations are challenging given the resource-constrained IoT setup. We have developed a lightweight identity-based cryptosystem suitable for IoT, to enable secure authentication and message exchange among the devices. Our scheme employs Physically Unclonable Function (PUF), to generate the public identity of each device, which is used as the public key for each device for message encryption.
