Continuous-variable quantum authentication of physical unclonable keys: Security against an emulation attack

Continuous-variable quantum authentication of physical unclonable keys: Security against an emulation attack
Georgios M. Nikolopoulos
We consider a recently proposed entity authentication protocol in which a physical unclonable key is interrogated by random coherent states of light, and the quadratures of the scattered light are analyzed by means of a coarse-grained homodyne detection. We derive a sufficient condition for the prot...
