Automotive processor IP complies with ISO 21434 cybersecurity

After the widespread adoption of the ISO 26262 functional safety standard in automotive designs, another standard is taking hold to protect connected vehicles from malicious cyberattacks. The ISO/SAE 21434 standard defines the engineering requirements for cybersecurity risk management to ensure that cyber risks are monitored, detected, and mitigated throughout the vehicle’s lifecycle.

Today, Synopsys announced that SGS-TṺV Saar has certified its ARC HS4xFS processor IP for ISO/SAE 21434 cybersecurity standard. This processor IP has already been certified to the ISO 26262 standard and meets ASIL D Random and ASIL D Systematic compliance for safety-critical systems.

The Synopsys ARC HSxFS functional safety processors—optimized for high-performance embedded applications—feature a dual-issue, 32-bit superscalar architecture with a small area footprint and low power consumption. Its compliance with cybersecurity requirements will reduce design risk and accelerate time-to-market for safe and robust systems-on-chips (SoCs).

But what’s driving the adoption of the ISO/SAE 21434 cybersecurity standard? For a start, cars are increasingly becoming software-defined while automakers add new features or functions remotely through over-the-air (OTA) software updates. Then there are other connected applications like vehicle telematics and smartphone connectivity.

So, the United Nations Economic Commission for Europe’s UN R155 regulation now mandates that automotive OEMs adopt a cybersecurity management system like ISO/SAE 21434. Automotive chip vendors are also acknowledging the critical importance of ISO 21434-certified IPs.

“As a supplier of highly reliable microcontrollers for use in automotive systems, it is critical that our products meet automotive cybersecurity standards to minimize the vulnerability to cyberattacks,” said Joerg Schepers, VP for automotive microcontrollers at Infineon.

IP suppliers like Synopsys complying with the ISO/SAE 21434 cybersecurity standard show that the automotive industry is starting to address evolving cybersecurity threats. After the automotive industry recognized the vital need for safety, engineers are now focusing on security in chips for connected vehicles.
