Overview

Novel optimization technique improves identifiability in IoT device authentication, enhancing security and efficiency.

Key Points

  • This work aims to enhance the identifiability of compensated measurement PUFs for IoT device authentication.
  • Introduced a novel optimization technique using weight masks on PUF parameters.
  • Tested technique on various PUFs constructed from public datasets.
  • Required only a small subset of devices for training to generalize to a larger population.
  • Improved Equal Error Rate (EER) by up to two orders of magnitude.
  • Proven generalizability of mask parameters to larger sets of devices.
  • Technique does not require additional hardware resources, preserving device efficiency.
