The QDID PUF, a core offering from Crypto Quantique, leverages quantum tunneling current variations to generate unique, unforgeable device identities. This patented Physical Unclonable Function (PUF) technology generates identities based on oxide thickness variations within standard CMOS processes, creating an unpredictable and secure hardware root-of-trust.
Instead of relying on stored identities that are vulnerable to tampering and side-channel attacks, QDID PUF creates identities dynamically on demand. This approach minimizes security risks associated with permanent identity storage and makes the system robust against attacks such as counterfeiting and cloning.
The IP is optimized for various cryptographic applications, including key generation and device authentication, making it suitable for high-security environments in medical, industrial, and IoT applications. Its design ensures compliance with rigorous security standards and its adaptability extends to integration in diverse hardware platforms, providing a versatile and secure solution.
Moreover, QDID PUF is validated across multiple manufacturing nodes and process technologies, ensuring its reliability and performance in different environmental conditions, further underscoring its suitability for long-term deployment in a range of applications. Its robustness across voltage and temperature variations reinforces its capability as a secure element in electronic devices.
