The EdgeLock SE052F enhances security for IoT devices by implementing cryptographic functions.

NXP Semiconductors unveiled a new hardware-secure component for industrial IoT (IIoT) applications—the EdgeLock SE052F—authorized for FIPS 140-3 Level 3 and the Common Criteria EAL 6+. It’s capable of cryptography functions like ECDSA and ECDH/E leveraging NIST (521-bit key length) and Brainpool curves, RSA (4K) with key generation, and AES modes CCM/GCM/CTR/ECB/CBC. The EdgeLock SE052F also handles HMAC, CMAC, GMAC, SHA-1, SHA-224/256/384/512.

The EdgeLock SE052F, which packs up to 100 kb of secured flash user memory, features advanced security such as secure credential injection with end-to-end encryption and secure binding with host MCU/MPU and bus encryption. It’s well-suited for smart factories, smart cities, healthcare, and other industries, providing high security while complying with the most recent FIPS requirements.
