Physical Realization of a Hyper Unclonable Function. (arXiv:2301.02147v1 [cond-mat.mes-hall])

Disordered photonic structures are promising materials for the realization of
physical unclonable functions (PUF), physical objects that can overcome the
limitations of conventional digital security methods and that enable
cryptographic protocols immune against attacks by future quantum computers. One
PUF limitation, so far, has been that their physical configuration is either
fixed or can only be permanently modified, and hence allowing only one token
per device. We show that it is possible to overcome this limitation by creating
a reconfigurable …
