Quantum One-Way Functions and Related Cryptographic Primitives
Georgios M. Nikolopoulos
Quantum cryptographic primitives beyond key distribution remain a less well understood area of research. In classical cryptography, one-way functions underpin nearly all standard c…
Noise-limited secret key agreement with twin optical physically unclonable functions
Georgios M. Nikolopoulos
We investigate the use of twin optical fingerprints derived from correlated physical unclonable functions (PUFs), as a hardware-based platform for cryptographic key generation and…
Dynamic Switched Quantum Key Distribution Network with PUF-based authentication
Persefoni Konteli, Nikolaos Makris, Evgenia Niovi Sassalou +7
We demonstrate a centrally controlled dynamic switched-QKD network, with integrated PUF-based dynamic authentication for each QKD link. The performance of the dynamic switched-QKD…
Minimum-error state discrimination and Fano's inequality
Georgios M. Nikolopoulos
The discrimination between non-orthogonal quantum states plays a pivotal role in quantum information processing and quantum technology. Strategies that minimize the error probabili…
Quantum Diffie-Hellman key exchange
Georgios M. Nikolopoulos
The Diffie-Hellman key exchange plays a crucial role in conventional cryptography, as it allows two legitimate users to establish a common, usually ephemeral, secret key. Its secur…
Quantum key distribution with post-processing driven by physical unclonable functions
Georgios M. Nikolopoulos, Marc Fischlin
Quantum key-distribution protocols allow two honest distant parties to establish a common truly random secret key in the presence of powerful adversaries, provided that the two use…
