Features & Featured Articles
security
Depending on the product and series, features such as secure boot, secure updates, Arm TrustZone, cryptographic accelerators, key management, and lifecycle management are included.
✓ Provides security functions that serve as a foundation when considering compliance with cybersecurity regulations such as CRA , and national/regional certification/labeling systems such as Japan's JC-STAR . ✓ With MCX N, the Root of Trust can be implemented in hardware (internal ROM) , making secure boot more secure. ✓ The MCX A5 also features PQC (Post-Quantum Cryptography) functionality. ✓ Some products have obtained third-party certifications such as SESIP, and can be used as evidence.
