Absolute Security in High-Frequency Wireless Links. (arXiv:2208.05907v1 [cs.IT])

Security against eavesdropping is one of the key concerns in the design of
any communication system. Many common considerations of the security of a
wireless communication channel rely on comparing the signal level measured by
Bob (the intended receiver) to that accessible to Eve (an eavesdropper).
Frameworks such as Wyner's wiretap model ensure the security of a link, in an
average sense, when Bob's signal-to-noise ratio exceeds Eve's. Unfortunately,
because these guarantees rely on statistical assumptions about noise, Eve can …
