An Extended PUF-based Protocol

Francesco Berti

Itamar Levi

Abstract

We extend a PUF-based authentication protocol with key refresh, hierarchical groups, and revocation. Our framework enables secure communication among enrolled devices without server interaction, allowing group leaders to derive subordinate keys and the server to exclude compromised parties through controlled key updates.
