2025 Expected to be a Pivotal Year for SEALSQ and WISeKey in Quantum and Post-Quantum Technologies

Geneva, Switzerland, Jan. 02, 2025

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 that 2025 is expected to be a landmark year for SEALSQ and its parent company WISeKey International Holding Ltd. (“WISeKey”) (SIX: WIHN, NASDAQ: WKEY) as they advance their leadership in quantum technologies. SEALSQ is focusing on breakthroughs in post-quantum algorithms and semiconductor innovations, while WISeKey is reinforcing its Public Key Infrastructure (PKI) with a quantum root key to address the challenges of the quantum era.

SEALSQ and WISeKey are collaborating with the National Institute of Standards and Technology (NIST) National Cybersecurity Center of Excellence (NCCoE) on the development of the first Quantum-Resistant USB Token demonstrator, an initiative driven by their Post-Quantum Engineering team.

This initiative, part of the SEALSQ QUASARS project (Quantum-Resistant Secure Algorithms on Silicon), incorporates state-of-the-art algorithms like CRYSTALS-Kyber and CRYSTALS-Dilithium, which are among the finalists in the NIST Post-Quantum Cryptography Standardization process. These quantum-resistant algorithms are being implemented in SEALSQ’s proprietary semiconductors, combining cryptographic robustness with energy-efficient designs tailored for embedded and IoT applications.

SEALSQ’s collaboration with NCCoE is revolutionizing the way IoT devices are onboarded and managed:

• Secure device provisioning and lifecycle management: By introducing trusted network-layer onboarding protocols, SEALSQ ensures secure device provisioning and lifecycle management. Their semiconductors integrate advanced secure elements, which provide tamper-resistant storage for cryptographic keys and enable post-quantum IoT authentication using quantum-resistant digital signatures. These features protect devices against quantum-enabled attacks and unauthorized access while enabling remote lifecycle management, including secure provisioning, updating, and decommissioning.
  
  
• Efficient performance even in resource-constrained environments: SEALSQ’s quantum-resistant solutions rely on semiconductor innovations featuring dedicated hardware accelerators for lattice-based cryptography, ensuring efficient performance even in resource-constrained environments. These chips are designed for low power consumption, making them ideal for IoT applications. The embedded trust anchors provide secure key injection during manufacturing, granting each device a unique and immutable identity. This robust approach establishes a foundation for IoT security, addressing current and future threats posed by quantum computing advancements.
  
  
• The collaboration with NCCoE and other leading technology providers extends beyond technical innovation: The collaboration establishes new standards for securing IoT devices and networks, ensuring interoperability and scalability across industries such as healthcare, automotive, and smart cities. This initiative is supported by a consortium of technology partners and collaborators. SEALSQ’s secure onboarding protocols prevent unauthorized device access, secure data-in-transit and data-at-rest, and provide resilience against quantum threats.
  
  

Of note, SEALSQ’s collaborating with NCCoE in the Migration to Post-Quantum Cryptography Building Block Consortium aims to bring awareness to the issues involved in migrating to post-quantum algorithms and to develop practices to ease migration from current public-key algorithms to replacement algorithms. NIST does not evaluate commercial products under this Consortium and does not endorse any product or service used.
