Safe and Secure Industry Automation

Industry 4.0 is gaining momentum. Ensured security with high availability in machine-to-machine networks is required to maximize the value of a connected factory. The Renesas security solution provides a root of trust, with strong security at the semiconductor level, facilitating the development of safe and secure equipment.

Trusted Secure IP, hardware security IP built into the Renesas MCUs (e.g. RX MCU and RZ MPU), allows for protection of keys and the cryptography engine. Keys are secured by an access protection mechanism within the encryption engine, with a proprietary unique ID based authentication to prevent unauthorized access.

Security Solution


RX security solutions implement a Root of Trust for IoT devices using encryption by key data that is protected by a strong Trusted Secure IP, and a memory-protected authentication program. By implementing security functions using an RX microcontroller (MCU), you can easily and strongly protect IoT devices against threats.
