SEALSQ Presents Research on Side-Channel Attacks Against ML-KEM

Insider Brief

• SEALSQ presented peer-reviewed research at LightSec 2026 on a side-channel attack targeting the encoding step of ML-KEM key generation, along with countermeasures to reduce implementation vulnerabilities.
• The research combines profiling-based techniques with lattice reduction to recover sensitive information from side-channel leakage under realistic conditions.
• The work examines implementation risks in NIST-standardized post-quantum cryptography and complements SEALSQ’s hardware security development, including its QS7001 secure element, which is undergoing Common Criteria EAL5+ certification.

PRESS RELEASE — 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 its research team presented a peer-reviewed technical article on a novel side-channel attack targeting the encoding step of ML-KEM (Module-Lattice-Based Key Encapsulation Mechanism, formerly CRYSTALS-Kyber) key generation at LightSec 2026.

LightSec 2026, the 7^th International Workshop on Lightweight Cryptography for Security & Privacy, took place on October 11, 2026, in Antalya, Turkey, as an official affiliated event of CHES 2026 (Conference on Cryptographic Hardware and Embedded Systems), the premier venue for research on the design and analysis of cryptographic hardware and embedded systems. The broader CHES program runs from October 11–15, 2026.
