Overview

Creating a secure product requires a full set of security solutions. Renesas will guide you through the design and implementation of a secure, connected application, from basic security concepts, to advanced topics such as key handling and cloud connectivity, and finally mass production and secure firmware updates.

All items will be demonstrated using Renesas MCU products with their powerful security feature sets

Security Solutions

Renesas RA Family Microcontrollers

Renesas RA MCUs deliver the ultimate combination of optimized performance, security, connectivity, peripheral IP, and an easy to use Flexible Software Package (FSP) to address the next generation of embedded solutions. Designing with RA MCUs makes it easy for embedded engineers to develop Internet of Things (IoT) edge devices for industrial and building automation, metering, healthcare, and home appliance applications.

The RA Family of Arm MCUs incorporate a selection of hardware-based security features, from simple AES acceleration to fully integrated crypto subsystems (Secure Crypto Engines, or SCEs) that are isolated within the MCU. The RA6 series based on the Cortex®-M4 core also offers the added benefit of NIST CAVP certification plus PSA Certified™ Level 1. The RA4 and RA6 series devices based on Cortex-M33 core further expand the MCU security capabilities with the addition of next generation SCEs, Arm®v8-M TrustZone®, and Trusted Firmware M, validated by additional NIST and PSA certifications. The combination of NIST CAVP certifications for functional correctness combined with the holistic perspective offered by PSA Certified gives Renesas customers an unprecedented level of assurance and confidence for developing their secure product for the connected world.

Renesas Synergy™ Microcontrollers

The Renesas Synergy MCUs, forming the basis of the Synergy Platform, provide hardware security features previously available only in dedicated Secure Element chips that were developed for specialized, highly secure identity applications (e.g. SIM cards, VPN tokens, etc.) The MCU's high level of integration eliminates the need for another chip, a socket, and a communications bus (I2C bus). This reduces the size, complexity, power consumption, and cost of the circuit board.

Renesas RZ Microprocessors

RZ/A2M Group's security function supporting products are equipped with a hardware encryption IP called Trusted Secure IP (TSIP). TSIP for RZ/A2M supports integrity check of user program by secure boot, setting of unique ID for each chip, and protection of encryption key and prevention of unauthorized access. These features are implemented by hardware and they realize a Root of Trust for IoT solutions.
