Automotive Security Product Portfolio

Renesas automotive SoC (R-Car) and MCUs (RH850, RL78) include HSMs (hardware security modules) and dedicated cryptographic accelerators to integrate automotive cybersecurity that meet or exceed customer demands for cybersecurity.

Software Infrastructure for Fast Time-to-Market

The Renesas ICU firmware, high-quality security modules specifically designed for Renesas HSM, supports various security functions such as cryptographic and system services to fulfill the security requirements of the vehicle platform.

*This software is a Low Level Driver (LLD) for ICU-M (Intelligent Cryptographic Unit Master) of Renesas R-Car SOC and RH850 MCU. ICU-M LLD is also planned to be expanded to future R-Car SOC and RH850 MCU. Renesas provides it as reference driver with source code, which supports the Cryptographic accelerators on ICU-M.

Security Stack Partners

Renesas’ trusted partners offer a wide variety of efficient and flexible software stack for Renesas HSM that enable system developers to concentrate on high-level software development, without having to worry about low-level or hardware-specific issues.
