SEALSQ QS7001 Quantum-Resistant Secure Element Delivers Immediate CNSA 2.0 Compliance with Hardware-Embedded Post-Quantum Cryptography

Geneva, Switzerland, Nov. 25, 2025 (GLOBE NEWSWIRE) --

SEALSQ Corp (NASDAQ:LAES), ("SEALSQ" or "Company"), a leader in scalable semiconductor and cybersecurity solutions, today announces that its already-launched QS7001 Quantum Shield secure element, is fully ready to deliver immediate CNSA 2.0 compliance. This production-proven chip embeds NIST-standardized post-quantum cryptography (PQC) directly into hardware, enabling organizations to transition to quantum-resistant architectures today while maintaining full compatibility with existing systems. Designed for a broad range of security-critical environments, the QS7001 provides robust protection against current and future cryptographic threats, supporting the wide adoption of next-generation security standards.

The QS7001, already in volume production and shipping to customers worldwide, remains the industry's first commercially available hardware-embedded PQC secure element, built on a 32-bit Secured RISC-V Architecture Microcontroller to deliver unmatched performance and security for resource-constrained environments. By integrating quantum-resistant algorithms at the silicon level, the QS7001 eliminates the vulnerabilities inherent in software-only implementations, such as side-channel attacks and performance bottlenecks. This immutable hardware approach ensures end-to-end protection against "Harvest Now, Decrypt Later" threats, where adversaries collect encrypted data today for future quantum decryption.

At the core of the QS7001's CNSA 2.0 compliance are the NIST-standardized algorithms Module-Lattice-Based Key Encapsulation Mechanism (ML-KEM, formerly CRYSTALS-Kyber) for secure key exchange and Module-Lattice-Based Digital Signature Algorithm (ML-DSA, formerly CRYSTALS-Dilithium) for robust authentication and attestation. These algorithms enable hybrid cryptography models that bridge classical (e.g., ECC, RSA) and post-quantum schemes, facilitating a gradual migration without disrupting existing operations. The chip also supports secure boot mechanisms and firmware updates configurable for CNSA 1.0, CNSA 2.0, or mixed-mode deployments, further bolstering system integrity in connected IoT, industrial, and defense applications.

Complementing the QS7001, SEALSQ's newly launched U.S.-based Post-Quantum Root of Trust, operational since November 21, 2025, provides a complete ecosystem for generating CNSA 2.0-compliant Post-Quantum Certificates and device identities. This service integrates seamlessly with the QS7001 hardware, anchoring quantum-safe Public Key Infrastructure (PKI) and device attestation through global secure personalization centers in Switzerland, France, Spain, and forthcoming facilities in India and the U.S. Upcoming QVault TPM variants, slated for release in the first half of 2026, will extend this capability to trusted platform modules, accelerating compliance ahead of the 2027 U.S. government deadline for quantum-resistant cryptography.

"Quantum computing is no longer a distant threat, it's an imminent reality that demands immediate action," said Carlos Moreira, Founder and CEO of SEALSQ. "With the QS7001 already deployed in production systems worldwide, customers can achieve full CNSA 2.0 compliance today, benefiting from 10x performance gains, superior side-channel resistance, and tamper-proof security. By aligning with CNSA 2.0 and NIST standards from day one, we're equipping critical sectors, from defense and healthcare to energy and Bitcoin wallets, with unbreakable protection that exceeds regulatory mandates.

The QS7001's open hardware platform allows for custom firmware development, enabling rapid prototyping and deployment. It has achieved Common Criteria EAL5+ and FIPS 140-3 certifications, underscoring its enterprise-grade reliability. With a proven track record securing over 1.75 billion devices worldwide, SEALSQ's solutions are optimized for high-volume manufacturing through partnerships with foundries like UMC, supporting scalable adoption across embedded systems.

Developers can immediately begin integration using SEALSQ's comprehensive SDKs and evaluation kits, available now through the Company's secure developer portal. Production samples and volume orders of the QS7001 are shipping today. For more information on SEALSQ's post-quantum solutions and to order QS7001 devices, visit www.sealsq.com.
