Introducing Infineon’s Quantum-Ready Microcontrollers

In an era where digital security threats loom large, Infineon Technologies is taking proactive steps to prepare for the future. They’ve recently introduced the PSOC Control C3 Performance Line of microcontrollers, tailored to meet the impending challenges of post-quantum cryptography. These advanced units are designed to bolster industrial, data center, and power-conversion applications against potential risks posed by quantum computing.

Erik Wood, Infineon’s Senior Director of Security Technical Marketing, emphasized the urgency of this development. With quantum computing capabilities on the rise, traditional encryption methods face potential obsolescence, making it essential for chip manufacturers to innovate and prepare for PQC advancements. Infineon’s new microcontrollers integrate legacy and cutting-edge PQC algorithms through a hybrid architecture, offering built-in support for Leighton-Micali Signature (LMS) schemes to enhance firmware update security.

Security Innovations and Future-Ready Features

The PSOC Control C3 series is also equipped with crypto-agile APIs, allowing developers to adapt to evolving PQC standards without overhauling existing firmware. This feature preserves software relevance as PQC technologies advance. Compliance with the U.S. National Security Agency’s Commercial National Security Algorithm Suite 2.0—a directive for transitioning to quantum-resistant standards—further emphasizes Infineon’s forward-thinking approach.

Infineon’s commitment extends to its hardware security engine, the Low-Cost Crypto Subsystem (LCSS), which combines efficiency in power consumption with cutting-edge encryption methodologies. A seamless integration with Infineon’s ModusToolbox facilitates PQC-compliant implementations. Full-scale production of these microcontrollers is on the horizon for 2026, indicating Infineon’s dedication to securing future technological landscapes.
