*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.
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.
|ESCRYPT||An innovative and flexible HSM security firmware - CycurHSM - that ensures secure boot of the ECU, secure in-vehicle communication, ECU component protection and secure flashing.|
|Vector||An efficient and flexible software stack for hardware security modules – veSHM - that is adaptable to user’s use case in order to improve cybersecurity.|
|Elektrobit||A complete firmware software stack for a hardware security module (HSM) that implements security algorithms utilizing hardware acceleration mechanisms.|
