The QDID PUF represents the next generation of device identity technology, focusing on creating a secure and unforgeable means of identification through quantum-driven physical unclonable functions. This innovative IP harnesses the unique variations in CMOS gate oxide to generate identities through unpredictable current variances, ensuring each is unique and securely rooted in the hardware itself. This method provides a robust foundation for building secure architectures, as identities are generated on-the-fly without the need for memory storage, preserving them from potential side-channel attacks.
The QDID PUF is engineered to accommodate a high number of entropy seeds, with customizable security levels reaching up to 256 bits. The technology is resistant to machine-learning attacks, ensuring the integrity and security of device identities throughout their operational lifecycle. Tested across various environmental conditions, QDID PUF maintains its robustness, operating efficiently in a temperature range of -40°C to 125°C, and supports a lifetime of over 25 years.
Beyond security, the QDID PUF aids in simplifying the manufacturing and provisioning processes. It's integrated seamlessly into IoT devices, streamlining identity management and reducing risks associated with external provisioning methods like key injection. This intrinsic security, combined with its capability to support numerous process technologies like Bulk CMOS, FDSOI, and FinFET, makes the QDID PUF an adaptable and future-proof component of Crypto Quantique’s security solutions.
