PUF IP for Automotive Market: Where Security and Safety Meet
Modern vehicles are rapidly evolving into intelligent Physical AI platforms. ADAS, autonomous driving, intelligent cabins, EV power management, and vehicle-to-everything (V2X) communications increasingly depend on AI to perceive, reason, and act. In these systems, every AI decision depends on the authenticity of the hardware executing it—while a single hardware malfunction in a safety-critical system can have life-threatening consequences.
This dual challenge is codified in two landmark standards: ISO 26262 for functional safety and ISO/SAE 21434 for automotive cybersecurity. As SoCs grow more complex and vendors multiply, pre-certified, silicon-level security IP is no longer a convenience—it is a necessity. Synopsys Automotive PUF IP delivers just that, an unclonable silicon fingerprint that resists invasive and non-invasive attacks and provides the security foundation to protect assets across the entire vehicle life cycle.
Key Benefits
- Scalable across all foundries and process nodes, from 350 nm down to 2nm
- No sensitive key material present on device
- High protection against tampering and invasive attacks
- Resistant to post-quantum attacks
- Empirically proven secure and reliable for the entire product life
Hardware-based Security with PUF Technology
Synopsys PUF technology rests on a simple principle: every SRAM cell powers up with a random value determined by local silicon variations, creating a unique, unclonable silicon fingerprint. From it, device-unique cryptographic root keys are derived that are never stored—they are regenerated only when needed and exist in the chip only briefly, making them nearly impossible to clone, extract, or steal, even with physical access.
Because it uses standard SRAM available upon initial release of any process technology, the IP is node-agnostic—one design works across every foundry and process node with no per-node tuning or re-qualification.
Synopsys Automotive PUF
Synopsys PUF Premium is the industry-leading, certified PUF IP that lets designers secure products with internally generated, device-unique keys—without storing secret keys. Synopsys also offers an Automotive PUF Premium variant: the industry's first PUF IP certified for both ISO 26262 (ASIL B Random, ASIL D Systematic) functional safety and ISO/SAE 21434 cybersecurity. Built on more than 15 years of SRAM PUF technology deployed in over 1.5 billion devices, it converges safety and security in one IP—redundant computations, error correction, and memory integrity checks meet safety requirements, while side-channel and fault-injection countermeasures and data-path integrity protect against cybersecurity attack vectors.
Use Cases
- Trusted Supply Chain: device locked from fabrication; each owner locks their IP with device-unique keys throughout the life cycle.
- Flexible Key Provisioning: generate an almost unlimited number of keys for multiple applications.
- Anti-Cloning: binding proprietary IP to a unique device prevents cloning.
- Secure Communication: all system components are securely authenticated against eavesdropping and alteration.
- Multi-Die Security: device-unique keys protect communication and IP integrity across multi-die and chiplet-based designs.
