Now that today’s smart cars are running hundreds of millions of lines of code, vehicle security has become much more complicated. To protect private data and sensitive information in vehicles, it’s critical that automotive processors support the latest functional safety and cybersecurity standards.

SiFive has always been at the cutting-edge of vehicle safety, and we recently hit a new milestone by achieving ISO/SAE 21434 compliance. ISO/SAE 21434 is the first automotive-focused standard specifying a cybersecurity framework for next-generation software defined vehicles (SDVs). Our RISC-V automotive products already offer unparalleled design freedom and flexibility for the automotive market, and now our customers can design vehicle components with the confidence that our solutions meet the most demanding security requirements.

Let’s dive in further to explain why ISO/SAE 21434 is so important. The standard provides specific requirements for cybersecurity processes and establishes a common language for communicating and managing cybersecurity risk across the supply chain—protecting original equipment manufacturers (OEMs) and end users from cybersecurity threats. ISO/SAE 21434 certification is seen as a prerequisite for OEMs in selecting their suppliers, as this certification allows OEMs to meet the requirements for UN R155, a regulatory framework designed to ensure that vehicles are secure.
