In this paper, we consider the problem of secret key agreement in
state-dependent 3-receiver broadcast channels. In the proposed model, there are
two legitimate receivers, an eavesdropper and a transmitter where the channel
state information is non-causally available at the transmitter. We consider two
setups. In the first setup, the transmitter tries to agree on a common key with
the legitimate receivers while keeping it concealed from the eavesdropper.
Simultaneously, the transmitter agrees on a private key with each of the
legitimate receivers that needs to be kept secret from the other legitimate
receiver and the eavesdropper. For this setup, we derive inner and outer bounds
on the secret key capacity region. In the second setup, we assume that a
backward public channel is available among the receivers and the transmitter.
Each legitimate receiver wishes to share a private key with the transmitter.
For this setup, an inner bound on the private key capacity region is found.
Furthermore, the capacity region of the secret key in the state-dependent
wiretap channel can be deduced from our inner and outer bounds.
