Key Takeaways:

  • Introduces a comprehensive stochastic modeling framework that predicts the average entropy of SR-latch based TRNGs, considering both process mismatch (quantified via a mismatch-to-noise ratio) and device aging.
  • Simulations demonstrate no significant loss of entropy over seven years, suggesting inherent robustness of SR-latch TRNGs as reliable sources for cryptographic randomness.
  • Highlights the practicality of SR-latch TRNGs for high-throughput, long-term deployment—offering low overhead and sustained performance.

This research strengthens Allegro’s vision for trustworthy, resilient hardware-based security components in advanced communication systems.
