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, showcased the power of post-quantum cryptography (PQC) with live demonstrations of NIST-standardized Crystal Kyber (FIPS 203) and Crystal Dilithium (ML-DSA) algorithms on its secure devices during the “Quantum Days 2025” event held in France, on May 13.

Presented by Danielle Fonte, a member of SEALSQ’s Product Security Team, the demos underscored SEALSQ’s commitment to quantum-resistant security, aligning with broader efforts like Quantum Key Distribution (QKD) to safeguard connected systems against future quantum threats.

With quantum computing challenging traditional cryptography, SEALSQ is advancing PQC to deliver robust, scalable security for IoT ecosystems. Like QKD, which leverages quantum principles for secure key exchange, SEALSQ’s PQC solutions aim to protect data integrity and confidentiality in a quantum era. The Quantum Days demos featured two NIST-selected algorithms:

• Crystal Kyber: A key encapsulation mechanism (KEM) for secure key exchange over insecure channels, such as email. The demo showed Kyber enabling two parties to share a 256-byte secret using SEALSQ secure devices, protected against chosen ciphertext attacks.
• Crystal Dilithium: A digital signature algorithm (DSA) ensuring message authenticity and integrity. The demo verified Dilithium’s ability to sign and validate messages, critical for trusted IoT communications.

Conducted on SEALSQ’s latest quantum resistant hardware platform (QS 7001), the live demos illustrated real-world applications of PQC. The Kyber demo demonstrated secure key exchange, while the Dilithium demo confirmed message integrity, even detecting tampering. These capabilities position SEALSQ as a trusted partner for industries like automotive, healthcare, and smart infrastructure.

“Our Quantum Days demos of Kyber and Dilithium on SEALSQ devices showcase our commitment to future-proof security,” said Mr. Fonte. “We’re proud to deliver NIST-compliant solutions that protect customers against quantum threats.”

SEALSQ’s integration of PQC algorithms into its hardware ensures compliance with global cybersecurity standards and meets the growing demand for quantum-resistant IoT solutions. The Quantum Days event underscored SEALSQ’s leadership in shaping a secure digital future.
