We’re happy to announce that we’ve added support for Renesas RH850 in wolfHSM.
The RH850 Family of 32-bit automotive microcontrollers (MCUs) is an automotive microcontroller equipped with an integrated Hardware Security Module (HSM). It ensures fast and secure key management, cryptographic processing, and authentication at the hardware level. Designed for next-generation ECUs, it combines functional safety with advanced security.
wolfHSM is a framework that combines the cryptographic algorithms provided by the processor with software cryptographic processing by wolfCrypt, allowing you to flexibly extend the crypt algorithms as needed.
wolfSSL has now ported wolfHSM on Renesas RH850 F1KM. RH850 F1KM supports true random number generation and the AES block cryptographic algorithm on the HSM core. The wolfHSM client running on the main core requests cryptographic processing to the wolfHSM server running on the HSM core through shared memory. Random number generation and AES cryptographic processing can be offloaded to the HSM core. In addition, it is possible to delegate key generation and storage for public key cryptography algorithms to the HSM core. The generated keys are securely protected in flash managed by the HSM core.
If you are interested in porting wolfHSM to the RH850, including a sample wolfHSM server and client, or if you have questions about any of the above, please contact us at facts@wolfssl.com or call us at +1 425 245 8247.
