SEALSQ Corp’s research team presented a peer-reviewed paper at LightSec 2026 in Antalya, Turkey, on October 11, 2026, an event affiliated with CHES 2026. The paper addresses implementation security in post-quantum cryptography, an area that relates directly to the company’s product portfolio.
Side-channel vulnerabilities arising from power consumption, electromagnetic emissions, or timing remain a practical concern for lattice-based schemes, even where their mathematical foundations are secure. The concern applies particularly to resource-constrained and long-lived devices preparing for the transition to post-quantum cryptography.
The paper, titled “Cross-information lattice attack on ML-KEM,” describes a side-channel attack on the encoding step of ML-KEM key generation under realistic conditions. The method combines profiling-based techniques with lattice reduction, and the paper reports that this hybrid approach recovers sensitive information more effectively than prior methods alone. The authors also present countermeasures designed to improve the robustness of ML-KEM implementations against such attacks.
The research complements the company’s Quantum Shield QS7001, a secure element that embeds ML-KEM for key establishment and ML-DSA for signatures directly in hardware on a secured RISC-V architecture. The device includes hardware acceleration, countermeasures against SPA/DPA and related attacks, active shielding, and scrambling. The QS7001 is currently undergoing Common Criteria EAL5+ certification.
“Presenting peer-reviewed work on ML-KEM implementation security at a CHES-affiliated workshop underscores our dual role as both product innovators and contributors to the global cryptographic research community,” said Carlos Moreira, Founder, Chairman, and CEO of SEALSQ.
SEALSQ’s research and engineering teams continue to strengthen the company’s intellectual property portfolio, including prior work on side-channel protection for polynomial-based algorithms at the encoding stage. The company’s forward-looking statements involve risks and uncertainties, and SEALSQ does not undertake to update them.
