QDID PUF is a unique offering designed to generate a distinct identity for devices, leveraging the principles of quantum tunneling. The randomness essential to this process comes from natural variations in oxide thickness and the random distribution of defects in the gate oxide. These properties make the QDID PUF a foundational element for establishing hardware root-of-trust within a security architecture, ensuring robust protection against unauthorized access and attacks. The QDID technology excels in resisting side-channel attacks by creating on-demand and unique identities without needing permanent storage of cryptographic keys, further reducing risk and cost in secure device provisioning. With proven performance under varying environmental conditions, it ensures operational integrity over extended periods, contributing to the security of embedded systems.
