PUF security for ASIL D functional safety
Intrinsic ID has launched a Physical Unclonable Function (PUF) technology for functional safety in automotive systems.
The Intrinsic ID QuiddiKey 400 hardware root of trust has been developed following an ISO 26262 functional-safety-compliant flow and meets the ISO 26262 Automotive Safety Integrity Level (ASIL) B fault metric and ASIL D for systematics failures. It uses PUF technology that uses the variability fo SRAM cells in a chip to create a hardware-based RoT that secures and protects electronic systems and components.

RoT technology has become essential for protecting connected automotive components from tampering or from being cloned or counterfeited. Supply chain integrity is crucial for automotive safety. According to the Federal Trade Commission, counterfeit parts cost the automotive industry $12 billion a year globally and present significant safety risks. Counterfeit parts lack proper testing and may not function correctly, which can potentially result in loss of life when used in safety-critical equipment, such as braking systems, airbags, or seatbelts.
The United Nations Economic Commission for Europe (UNECE) introduced regulations R155 and R156 for connected vehicles in 2021. These regulations are intended to protect against vehicle cybersecurity threats and along with other industry standards, such as ISO/SAE 21434, are aimed to ensure vehicles are secure by design.
“Security threats are everywhere. This is particularly true for safety-sensitive markets like the automotive industry,” said Pim Tuyls, CEO of Intrinsic ID. “With everything connected to the internet, new government legislation, safety regulations, and higher security requirements are driving the need for strong security solutions. We saw the need to expand our acclaimed QuiddiKey product family with QuiddiKey 400, which has been developed to meet the most stringent automotive functional safety standards.”
QuiddiKey 400 provides a reliable RoT for ASIC, SoC, MCU and FPGA-based devices, which prevents attacks that can compromise functional safety and provides components with an unclonable identity to protect against counterfeiting. The new product is based on the Intrinsic ID core PUF technology that has already been proven in the field over more than a decade with no known breach or failure. QuiddiKey 400 scales across all foundries and process nodes and includes substantial protection against both software and hardware attacks to deny adversaries access to any key material or data, even on unmanned autonomous vehicles.
The Intrinsic ID QuiddiKey IP is the world’s first RoT IP to receive a SESIP and PSA Certified level 3 certification, it is NIST CAVP certified, ready for FIPS 140-3, and has been deployed and proven in more than 600 million devices, which have been certified by EMVCo, Visa, CC EAL6+, PSA Certified, ioXt, and governments across the globe.
QuiddiKey 400 is available now and can be integrated and scaled across all foundries and technology nodes.
