demonstrates the scenario whereby a base station is compromised. A hacked base
station can be detected and revoked by the other base stations using the new generated key
known as base station key (Kb). If a base station is hacked, it will not be aware of the updated
session key, which is also updated periodically, and continue to use its old key. In doing so, the
base station will not be involved in the data transmission, and the other remaining base stations
will identify that this base station is compromised. The authenticated base stations will send the
administrator a message indicating that one of the base stations is hacked. It is then up to the
administrator to remove it from the system or replace it with another one. However, there is
always a case whereby the opponent base station will act like an authenticated node and accuse
one of the other validated base stations of being hacked. The administrator will consider any of
the base stations to be hacked if at least more than one of the remaining three base stations
declares otherwise.
