Zirah: A Post-Quantum True Random Number Generator Hardware Signer With an Avalanche Noise

Zirah is an open-hardware post-quantum signer using avalanche-noise TRNG on an STM32 MCU—a practical research platform for studying PQ key exposure on constrained devices.

arXiv:2611.08200v1 Announce Type: new Abstract: Zirah is a hardware signer built around an STM32F407 microcontroller, and its purpose is to find out, on inexpensive hardware, where a post-quantum signing key is exposed and what actually protects it. The device draws every random bit from a reverse-biased 2N3904 junction in avalanche breakdown, amplified by an LM358 and screened by SP 800-90B health tests, computes ML-DSA-65 (FIPS 204, hedged) on the STM32 with two-share arithmetic masking of th

Editorial Analysis

Why it matters

Post-quantum migration is approaching; low-cost hardware signers help security teams understand practical key-protection challenges before enterprise-scale PQ rollouts.
