Security Solutions

rx security image

In response to growing threats to IoT devices, RX 32-bit microcontrollers (MCUs) provide security solutions that will protect against threats throughout the lifecycle of IoT devices, from autonomous security and the design phase to end-of-life.

This is a test image Features

Autonomous security for IoT endpoint devices is provided by Renesas' proprietary hardware secure IP (Trusted Secure IP)

IoT devices that are located in a network environment are constantly exposed to a variety of threats. However, if the IoT endpoint device itself is secure, it can protect itself from threats and prevent malicious and unauthorized behavior, even in an unsafe network environment. RX has strong security technology using Trusted Secure IP, Renesas' proprietary hardware for secure IP, and provides autonomous security for IoT endpoint devices.

Hardware: RX Microcontroller with Security Hardware IP to Protect Against Threats

RX is equipped with Trusted Secure IP, which cannot be accessed externally. Key data and the cryptographic engine in Trusted Secure IP are strongly protected. Also, it combines area protection features and RX-specific features to protect authentication programs from tampering threats. With this, you can build a system with Root of Trust that provides self-sustaining security and provides easy and robust protection from a variety of threats.

Software

We provide you with the drivers that make Trusted Secure IP work, as well as secure update and secure boot sample programs to use the RX-specific features so you can deploy security quickly and easily.

Software Components Description
Trusted Secure IP Driver Write keys and firmware to a dedicated driver that runs Trusted Secure IP for the microcontroller
Secure Updating A sample program that provides tamper detection/prevention by authentication when updating a program
(Included in Trusted Secure IP driver package)
Secure Boot A sample program that prevents hijacking by detecting tampering during program execution (stops execution)
(Included in Trusted Secure IP driver package)

dlm conAchieving DLM with RX Security Solutions

There are various threats during the lifecycle of a user's product. You need not only security features for the device, but also secure operations throughout the lifecycle to respond to these threats. This way of thinking is called Device Lifecycle Management (DLM). RX security solutions support DLM and also make robust and advanced security management from the product lifecycle operation aspect possible.
