Secret-Key Agreement Using Physical Identifiers for Degraded and Less Noisy Authentication Channels. (arXiv:2208.10478v3 [cs.IT] UPDATED)

Secret-key agreement based on biometric or physical identifiers is a
promising security protocol for authenticating users or devices with small
chips due to its lightweight security. In previous studies, the fundamental
limits of such a protocol were analyzed, and the results showed that two
auxiliary random variables were involved in the capacity region expressions.
However, with these two auxiliary random variables, the complexity of computing
the capacity regions may be prohibitively high. To deal with this problem, we
explore classes …
