Remote Quantum-Safe Authentication of Entities with Physical Unclonable Functions

Physical unclonable functions have been shown to be a useful resource of randomness for implementing various cryptographic tasks including entity authentication. All the related authentication protocols that discussed in literature so far, either they are vulnerable an emulation attack, or limited short distances. Hence, quantum-safe remote over large distances remains open question. In first part this work, we discuss requirements protocol has offer, practice. Subsequently, propose protocol, which can operate distances, and offers security against both classical quantum adversaries. The proposed relies on standard techniques, it is fully compatible with infrastructure existing future photonic networks, parallel other protocols, QKD protocols.
