ISO/SAE 21434 sets cybersecurity risk limits for road vehicles throughout their life cycle.
The firmware is called Microsar HSM, and it was certified using Infineon Aurix TC3xx MCUs, which have Infineon’s proprietary TriCore cores.
“The ISO/SAE 21434 certification of Microsar HSM confirms the use of state-of-the-art processes in automotive cybersecurity,” claimed the company. “This certification also helps meet the requirements of the supply chain for type approval of vehicles worldwide. In addition Vector now offers product-specific certification in accordance with ISO/SAE 21434 to support the implementation of UN Regulation 155.”
Hardware security modules within vehicle ECUs (electronics control units) protect against unauthorised access and manipulation.
The newly certified firmware accesses available security hardware resources to provide cryptographic functions, secure key memory and secure boot. MAC (message authentication code) is offered to enhance on-board network security, and TLS (transport layer security) protocol is available for off-car communication protection.
Pre-configured evaluation bundles for the firmware are available for Infineon TC37x (secure gateway / tasking compiler) or TC397x (tasking compiler), Renesas RH850 F1KM or RH850 U2A (both GreenHills compiler, or Taxas Instruments JACINTO7 (TI compiler).
Microsar HSM can be found on this Vector web page, and the certificate can be downloaded from test house Exida here
Late last year, Vector teamed up with development tool company PLS to created a timing analysis bundle for Microsar Classic, the functional code that Vectors pairs with Microsar HSM.
