Achieving Error-Free Lightweight Authentication With DRAM-Based Physical Unclonable Functions

Nico Mexis;Nikolaos Athanasios Anagnostopoulos;Stefan Katzenbeisser;Elif Bilge Kavun;Sara Tehranipoor;Tolga Arul

IEEE Transactions on Circuits and Systems I: Regular Papers
Year: 2025 | Volume: 72, Issue: 2 | Journal Article |
In this article, we introduce a novel approach to achieving lightweight device authentication through the use of a low-complexity Convolutional Neural Network (CNN). In our work, we improve the False Authentication Rate (FAR) by transforming the standard CNN into a Bayesian CNN (BCNN or BNN). This transformation enables the use of probabilistic modelling techniques, increasing the model’s robustne...Show More
