Overview

Analyzed the integration of voltage regulators in PUF designs, showing improved performance and security metrics.

Key Points

  • The proposed system demonstrates a 50% diffuseness, indicating a 31% improvement over a standard PUF implementation.
  • Achieved a consistent 48% uniformity when compared to standalone PUF systems, enhancing reliability.
  • Statistical analyses used 8K challenge-response pairs from three chips to validate improvements in the new PUF design.
  • Exhibits greater resilience against machine learning attacks with a prediction accuracy of 50.5%, far better than 67.1% for traditional PUF.
