Physical unclonable functions (PUFs) are complex physical objects that aim at overcoming the vulnerabilities of traditional cryptographic keys, promising a robust class of security primitives for different applications. Optical PUFs present advantages over traditional...

While still far from practical implementation, the prospect of ultra-powerful quantum computers has raised significant concerns about information security. That’s because a true quantum machine could quickly undermine the classical security protocols on which the...

Protecting confidential data is a major challenge in the internet era. Standard cryptographic techniques are fast and scalable, but they are broken by quantum algorithms. Quantum cryptography is unclonable and more robust, but requires quantum installations that are...
