Researchers from SEALSQ introduced a paper exploring cross-information lattice attacks on ML-KEM at the LightSec 2026 workshop. The work highlights risks in cryptographic implementations and proposes hardware-level countermeasures.
Why it matters
As lattice-based cryptography becomes a standard for quantum-resistant security, understanding implementation flaws is vital to protecting sensitive data. The study provides a roadmap for hardening hardware against side-channel exploitation.
The researchers utilized a combination of profiling-based techniques and lattice reduction to exploit leakage during ML-KEM key generation. The Quantum Shield QS7001 secure element currently seeks Common Criteria EAL5+ certification.
The players
SEALSQ

The Tech Race
This research reflects the ongoing industry effort to secure post-quantum cryptographic standards against physical side-channel attacks. It moves beyond theoretical modeling to address the practical implementation challenges faced by modern secure hardware.
This development suggests that future hardware devices will incorporate more robust shielding to protect encrypted data from physical observation. Users and developers can expect improved security benchmarks as products like the QS7001 achieve higher safety certifications.
The takeaway
Security research demonstrates that even advanced cryptographic standards require rigorous hardware protection to prevent side-channel leaks. Implementing active shielding remains a primary strategy for ensuring device robustness in the quantum era.
