Overview
Anything that is connected to the internet is at risk, and connected vehicles are no exception. Every connected electronic component represents a potential entry point for malicious intrusion—into the component itself or onto the network to which it is connected. Root-of-trust (RoT) technology is becoming an essential requirement for components in autonomous vehicles which now need to adhere to the industry standard ISO/SAE 21434 to ensure the vehicle fleet is secure by design.
Synopsys AP PUF is a physical unclonable function (PUF)-based RoT component that can be applied easily to almost any MCU/SoC/ASIC and is fab and process agnostic. This IP has been developed following an ISO 26262 functional-safety-compliant flow and meets the ISO 26262 Automotive Safety Integrity Level (ASIL) B fault metric. It validates all inputs and critical internal logic through integrity checks and error detection. It continuously asserts that everything runs as intended and flags any observed faults. Additionally, Synopsys AP PUF offers the user hardware and software handholds to check whether all data is correctly transferred to and from the hardware-based PUF.
Just like Synopsys PUF Premium, which was the world’s first RoT IP to receive a SESIP and PSA Certified level 3 certification, Synopsys AP PUF includes substantial protection against both software and hardware attacks to deny adversaries access to any key material or data, even on unmanned autonomous vehicles.

This article provides an in-depth analysis of the specific PPA challenges introduced by PQC and elucidates how PUF-PQC leverages its unique dualtrack strategy to deliver a robust and flexible Hardware Root of Trust (HRoT) across diverse application scenarios. Furthermore, it demonstrates the integration of Physical Unclonable Function (PUF) with a NIST SP 800-90B compliant True Random Number Generator (TRNG) to serve as critical components of PUFrt (Root of Trust), ensuring the security of post-quantum key generation starting from the entropy source.
In this work, the authors present ioPUF+, which incorporates a novel Physical Unclonable Function (PUF) that generates unique fingerprints for Integrated Circuits (ICs) and the IoT nodes encompassing them.

This article covers the basics of what an SRAM PUF (physical unclonable function) is and how it works, as well as the functionality it offers in internet of things (IoT) security as the trust anchor for any device.
The security of AIoT devices has become increasingly important. In order to ensure that the system’s security functions are working effectively and protecting every node and edge device from information security risks, it is important to generate a unique root of trust in the security system rooted in the chip.
