For information security, software algorithms or hardware protocols are generally adopted. Software algorithms use pseudo-random numbers generated from one-way mathematical functions. Hardware protocols use physically unclonable functions (PUFs) that exploit, for example, manufacturing process variations in the physical microstructures of integrated circuits. Both solutions (software and hardware) are robust for classical computers but vulnerable in the age of quantum computers.
In this project, with the aim of developing secure cryptographic systems, we would like to use artificially engineered 2D structures, called quantum metasurfaces. More specifically, we propose the design and implementation of an optical cryptographic surface based on quantum metasurfaces, where optical PUFs are embedded in optical diffusion films, with micro/nano architectures, inspired by biological tissues.
This will allow obtaining a structure with unique randomness. Such a structure is difficult to decode and at the same time, it is high entropy, non-volatile, reconfigurable, ultra-low power, low cost, and environmentally friendly.
The resulting new cryptographic systems can currently be integrated with existing communication protocols and networks and used with quantum computers in the future.
