MEC175xB Embedded Controllers
The Rising Threat of Quantum Computing
As quantum computing continues to advance, traditional asymmetric cryptographic methods—such as RSA, Diffie-Hellman, and elliptic curve cryptography—are at risk of becoming obsolete, introducing new security challenges for embedded systems. Post-Quantum Cryptography (PQC) is emerging as the key to safeguarding sensitive data and firmware from future quantum-based threats. Governments and industry leaders are actively working to integrate PQC capabilities for the long-term protection of notebooks, desktops, industrial systems, and data centers.
To stay ahead of this shift, manufacturers must begin transitioning from CNSA 1.0 to the new NIST-approved CNSA 2.0 algorithms. The MEC175xB product family is designed to meet these next-generation security requirements, offering integrated PQC support—including ML-KEM, ML-DSA and LMS algorithms—to future-proof embedded platforms. With its robust hardware-based security architecture and PQC-enabled firmware, the MEC175xB series empowers OEMs to begin building quantum-resilient systems today.
