The rise of Edge AI demands robust security solutions, and the STM32N6, with its integrated Neural Processing Unit, stands out as a powerful platform for these applications. When paired with wolfSSL’s comprehensive security offerings, the STM32N6 becomes an even more formidable solution for secure Edge AI deployments.
The STM32N6 is the first STM32 MCU to feature a Neural Processing Unit, boasting 600 GOPS of AI processing power. Its advanced security features include a capable ROM for secure code loading, integrity checks, signature verification, and on-the-fly decryption. The Boot and Security Control (BSEC) peripheral further enhances security with OTP, hardware unique keys (SAES), and tamper detection.
To truly secure Edge AI on the STM32N6, wolfSSL provides a suite of products:
- wolfSSL/TLS: This lightweight SSL/TLS library enables secure communication, crucial for protecting data transmitted to and from Edge AI devices. It supports modern TLS 1.3 and can leverage hardware-based private keys and the on-chip Root Hardware Unique Key (RHUK) for enhanced encryption and decryption.
- wolfCrypt: As wolfSSL’s cryptographic engine, wolfCrypt offers a wide array of asymmetric and symmetric algorithms, including RSA, ECDH, AES GCM/CCM, SHA2, and Post Quantum algorithms like ML-KEM and ML-DSA. It holds FIPS 140-3 Level 1 certification, ensuring high-grade cryptographic security.
- wolfBoot (coming soon): This secure bootloader, designed for bare-metal use, will provide a crucial layer of protection by ensuring that only authenticated and authorized firmware can run on the STM32N6. It supports asymmetric verification, integrity checks, encrypted updates, and hardware-based keystores.
By combining the STM32N6’s advanced Edge AI capabilities and security features with wolfSSL’s robust TLS, cryptographic, and upcoming secure bootloader solutions, developers can build highly secure and performant Edge AI applications. This integration ensures data integrity, confidentiality, and authenticity, which are paramount for the trustworthiness of AI at the edge.
