Infineon Technologies AG (FSE: IFX / OTCQX: IFNNY) has announced that its microcontrollers (MCUs) in the new PSOC™ Control C3 Performance Line family are compliant with Post-Quantum Cryptography (PQC) requirements for firmware protection outlined in the Commercial National Security Algorithm (CNSA) Suite 2.0. The MCUs also support PSA (Platform Security Architecture) Level 3 compliance, which is intended to meet the security needs of industrial applications.
The PSOC Control C3 family of MCUs provides real-time control for applications such as motor control and power conversion. The MCUs’ PQC features include support for Leighton-Micali Hash-Based Signatures (LMS), a PQC firmware verification algorithm integrated with SHA-2 hardware acceleration. Infineon’s Edge Protect Tools and ModusToolbox™ will support provisioning of LMS keys and options for hybrid PQC, where both LMS and Elliptic Curve Cryptography (ECC) can be used to sign firmware updates.
By complying with the CNSA Suite 2.0 and PSA Level 3, Infineon aims to support the transition to increased security in the PQC era for a wide range of industrial applications. The MCUs are designed for systems in data centers, telecom, solar, and electric vehicle (EV) charging. Samples of the PSOC Control C3 Performance Line with PQC compliance will be available in late 2025, with production of dedicated parts beginning in 2026.
