en.Wedoany.com Reported - SEALSQ Corp, a post-quantum semiconductor supplier, announced that its QS7001 post-quantum secure element has obtained Entropy Source Validation (ESV) certificate #E333 from the National Institute of Standards and Technology (NIST). The validation, conducted by accredited laboratory SERMA Safety and Security in accordance with the NIST SP 800-90B standard, confirms the performance parameters of the chip's internal random bit generation hardware. Completing this assessment is a core technical prerequisite for the hardware platform in its progression toward formal FIPS 140-3 and Common Criteria EAL5+ security certifications, as a validated baseline of physical unpredictability is a mandatory architectural requirement under modern cryptographic evaluation frameworks.
The validated architectural layer within the QS7001 utilizes a hardware noise mechanism constructed from a series of mutually interconnected ring oscillators. To convert the raw thermal jitter and phase noise of the silicon components into standardized, unbiased cryptographic keys, SEALSQ's engineering team in Meyreuil, France, collaborated with its chip design subsidiary IC'ALPS to develop a rigorous mathematical random model for continuously tracking the behavior of the physical noise source. This validated design has achieved an "Open Reuse" status in the NIST Cryptographic Module Validation Program (CMVP) registry, allowing SEALSQ to port this precise ring oscillator module to future hardware iterations, custom ASICs, and integrated partner modules without requiring a separate underlying entropy evaluation.
The validated physical entropy represents a critical step in SEALSQ's compliance roadmap for the QS7001. The QS7001 is designed around a secure 32-bit RISC-V microcontroller core, optimized for executing lattice-based post-quantum primitives such as ML-KEM and ML-DSA. Achieving standardized certification directly expands the hardware's addressable range within regulated procurement channels in the United States and the European Union, where uncertified cryptographic components face increasingly stringent restrictions under public sector defense directives like CNSA 2.0. By anchoring the hardware root of trust to an approved entropy source, the platform provides a predictable deployment path for Industrial Internet of Things (IoT) gateways, smart grid infrastructure, aerospace electronics, and embedded robotic controllers that require verified protection against advanced cryptographic interception threats.
