SEALSQ Accelerates Post-Quantum Readiness with Next-Generation TPMs Ahead of 2027 U.S. Government Deadline

Geneva, Switzerland, Sept. 04, 2025 (GLOBE NEWSWIRE) --

SEALSQ Corp (NASDAQ: LAES) ("SEALSQ" or "Company"), a company that focuses on developing and selling Semiconductors, PKI, and Post-Quantum technology hardware and software products, today announced major progress in its mission to deliver trusted hardware security modules designed for the quantum future.

The urgency is clear. The U.S. Government has set strict timelines for adopting quantum-resistant cryptography. Under the National Security Agency’s CNSA 2.0 policy, all new National Security Systems acquisitions must be compliant by January 1, 2027, with broader enforcement milestones extending into the next decade. Complementing this, the Office of Management and Budget Memorandum M-23-02 requires federal agencies to identify quantum-vulnerable systems and prepare migration budgets, putting post-quantum cryptography (PQC) at the center of national cybersecurity policy. In parallel, the National Institute of Standards and Technology (NIST) finalized the first PQC standards in August 2024, including FIPS 203 (ML-KEM) for key establishment and FIPS 204/205 (ML-DSA, SLH-DSA) for digital signatures, establishing the algorithms that will form the backbone of next-generation secure infrastructures.

Against this backdrop, SEALSQ is positioned as a pioneer in quantum-resistant hardware. Through close collaboration with industry leaders and standards bodies, SEALSQ is on track to deliver the first PQC-capable TPM samples featuring native hardware support for ML-DSA-87 and ML-KEM-1024 and to bring certified production parts to market, making SEALSQ among the earliest vendors to enable quantum-resistant Trusted Platform Modules (TPMs) aligned with the latest Trusted Computing Group (TCG) standard for TPM 2.0 V185, updated in July 2025 to include PQC algorithms.

Most importantly, and unlike some competitors which primarily support PQC for firmware updates via post-quantum signatures alongside classical algorithms like ECDSA, SEALSQ’s QVault TPM will offer full PQC capability across all TPM functions, integrated directly into the chip’s design. This involves incorporating PQC algorithms into the chip’s firmware and hardware logic, ensuring that quantum-resistant cryptographic functions (e.g., key generation, signing, and encryption) are performed directly by the TPM’s dedicated hardware to provide faster, more secure, and more efficient cryptographic operations compared to software-based implementation.

Trusted Platform Modules are already central to modern security architectures, supporting secure boot processes, hardware-based cryptographic key storage, and device authentication that underpins zero-trust deployments. They are widely used to safeguard encrypted disks, strengthen VPN and Wi-Fi authentication, and enable remote attestation in cloud and IoT ecosystems. TPMs also play a growing role in critical industries, protecting industrial control systems, securing healthcare and financial data, ensuring supply-chain authenticity, and supporting eGovernment identity programs. With the advent of quantum-resistant TPMs, these use cases are extended into the future, protecting sensitive infrastructures and digital identities against tomorrow’s quantum-enabled threats.

“The countdown to 2027 has already started,” said Carlos Moreira, CEO of SEALSQ. “Our customers, governments, enterprises, and critical infrastructure operators, require trusted hardware that not only meets today’s standards but is certified to withstand tomorrow’s threats. With QVault™ TPM, SEALSQ is proud to lead the way.”

As organizations worldwide confront the challenges of the quantum transition, SEALSQ’s innovation ensures that customers can begin migration now with confidence.
