Crypto Quantique

A patented analog PUF that derives identity from quantum-tunnelling current variations at the gate terminal, driven by oxide-thickness variation and random gate-oxide defects — works on any standard CMOS process, verified on TSMC, GlobalFoundries and UMC across Bulk CMOS, FDSOI and FinFET.

• Generates customizable security seeds up to 256 bits, produced on the fly rather than stored — resistant to side-channel memory extraction
• PSA Level 2 Ready and CC EAL4+ compliant, meeting NIST SP 800-22/SP 800-90B randomness and entropy standards
• Available at 65nm, 55nm, 40nm, 28nm and 22nm
• Foundries: GlobalFoundries, UMC and TSMC

A logic-based entropy source exploiting static mismatch in logic cells, with a built-in fuzzy extractor for error correction, configurable 128- or 256-bit output seeds, a typical footprint under 30k gates, and a post-correction failure rate of 1×10⁻⁹, validated against NIST SP 800-22/90B and BSI AIS31.
