Query: Multi-Entity and Multi-Enrollment Key Agreement with Correlated Noise   A basic model for key agreement with a remote (or hidden) source is extended
to a multi-user model with joint secrecy and privacy constraints over all
entities that do not trust each other after key agreement. Multiple entities
using different measurements of the same source through broadcast channels
(BCs) to agree on mutually-independent local secret keys are considered. Our
model is the proper multi-user extension of the basic model since the encoder
and decoder pairs are not assumed to trust other pairs after key agreement,
unlike assumed in the literature. Strong secrecy constraints imposed on all
secret keys jointly, which is more stringent than separate secrecy leakage
constraints for each secret key considered in the literature, are satisfied.
Inner bounds for maximum key rate, and minimum privacy-leakage and
database-storage rates are proposed for any finite number of entities. Inner
and outer bounds for degraded and less-noisy BCs are given to illustrate cases
with strong privacy. A multi-enrollment model that is used for common physical
unclonable functions is also considered to establish inner and outer bounds for
key-leakage-storage regions that differ only in the Markov chains imposed. For
this special case, the encoder and decoder measurement channels have the same
channel transition matrix and secrecy leakage is measured for each secret key
separately. We illustrate cases for which it is useful to have multiple
enrollments as compared to a single enrollment and vice versa.
