Security platform manages public key infrastructure for embedded IoT networks

Crypto Quantique demonstrated the QuarkLink Hybrid PQC security platform at Embedded World 2025. The company also showcased its latest analog and digital silicon IP offerings for device security.

QuarkLink is an integrated, scalable, cloud-based software platform that reduces the time and expense of implementing all necessary security functions in embedded device IoT networks and industrial PCs by up to 10X. It manages device identities, supports secure boot and firmware-over-the-air (FOTA) updates, and generates and manages security keys, digital certificates, and Public Key Infrastructure (PKI). This uniquely comprehensive set of functions enables embedded device developers to achieve European Cyber Security Resilience Act (CRA) compliance for devices faster, at lower cost, and with lower risk.

The Cyber Resilience Act (CRA) legislation establishes required timelines for implementation, with products needing to accept secure Firmware Over The Air (FOTA) updates by September 11, 2026, and full compliance with all aspects of the act required by December 11, 2027. This implementation process involves technical complexity, requiring embedded engineers to manage multiple tools, platforms, and processes simultaneously. The QuarkLink solution addresses these implementation challenges through its comprehensive feature set, simplifying compliance tasks for various stakeholders responsible for organizational cybersecurity, from development teams to Chief Security Officers.

QuarkLink integrates client libraries for popular MCU families and supports Linux distributions in industrial PCs. Recently updated with a post-quantum cryptographic algorithm, the platform provides security against classical attacks and future protection against threats from quantum computers. It also protects against “store-now/decrypt-later” attacks. In these, cybercriminals harvest encrypted data to decrypt in the future when more advanced computing resources become available.

Crypto Quantique also highlighted its growing family of lightweight root-of-trust silicon IP blocks and highly optimized cryptographic primitives. These are built upon the company’s proven physical unclonable function (PUF), QDID, and a quantum random number generator (QRNG), both of which are NIST compliant, PSA Level 2 Ready, and CC EAL4+ compliant.
