Statistical Analysis Based Feature Selection Enhanced RF-PUF with >99.8% Accuracy on Unmodified Commodity Transmitters for IoT Physical Security. (arXiv:2202.05684v1 [cs.CR])

Due to the diverse and mobile nature of the deployment environment, smart
commodity devices are vulnerable to various attacks which can grant
unauthorized access to a rogue device in a large, connected network.
Traditional digital signature-based authentication methods are vulnerable to
key recovery attacks, CSRF, etc. To circumvent this, RF-PUF had been proposed
as a promising alternative that utilizes the inherent nonidealities of the
devices as physical signatures. RF-PUF offers a robust authentication method
that is resilient to key-hacking methods …
