SEALSQ Corp (NASDAQ: LAES) announced that its QS7001 Post-Quantum Secure Element has achieved NIST Entropy Source Validation Certificate #E333 under SP 800-90B standard. The validation was confirmed on May 27, 2026, with testing performed by SERMA Safety and Security, an accredited laboratory in France.

The SP 800-90B standard governs testing and validation of entropy sources used in random bit generators for cryptographic applications. A validated entropy source is required for achieving FIPS 140-3 certification of cryptographic modules and Common Criteria EAL5+ certification.

SEALSQ's QS7001 entropy source uses a ring oscillator-based physical noise source and has been classified as a physical noise source with "Open for Reuse" status. This classification enables broader adoption across future SEALSQ products and partner integrations requiring compliant entropy generation.

The validation involved collaboration between SEALSQ's semiconductor engineering teams in Meyreuil, France, the IC'ALPS subsidiary, and SERMA Safety and Security testing laboratory. The submission included development of a stochastic model of the entropy source and detailed noise source characterization.

"Achieving NIST SP 800-90B Entropy Source Validation for our QS7001 is a critical and hard-earned milestone," said Carlos Moreira, CEO of SEALSQ. "Without a validated entropy source, no cryptographic module can claim FIPS 140-3 compliance."

The QS7001 is designed for hardware-based quantum-resistant security in IoT devices, industrial systems, government applications, and critical infrastructure. The certification supports SEALSQ's pipeline of opportunities in regulated markets where FIPS-validated cryptographic modules are mandatory for government procurement.
