The goal of this project is to conduct research focussed on providing new technology that remains safe in the post-quantum era, ensuring the integrity of digital services. To achieve that, we tackle the main challenge ahead for optical PUFs: realising their miniaturisation. To do it, we will develop robust cryptographic primitive that can be implemented in a photonic integrated circuit fabricated using standard CMOS. For that aim, we will first design a photonic circuit implementing the functionality of a strong PUF. Then, we will design a series of basic elements also required for developing a security system capable of generating cryptographic keys based on the PUFs digital signature, such as the XOR operation and basic permutations. Achieving these goals will allow us to realise strong PUFs compatible with electronic devices, especially in the context of IoT devices, which pose severe constraints on memory sizes and power consumption.Project PID2024-157963OB-C22 funded by MICIU/AEI /10.13039/501100011033 and by FEDER, EU.
