Query: Secure Multicast Communications with Private Jammers   This paper investigates secrecy rate optimization for a multicasting network,
in which a transmitter broadcasts the same information to multiple legitimate
users in the presence of multiple eavesdroppers. In order to improve the
achievable secrecy rates, private jammers are employed to generate interference
to confuse the eavesdroppers. These private jammers charge the legitimate
transmitter for their jamming services based on the amount of interference
received at the eavesdroppers. Therefore, this secrecy rate maximization
problem is formulated as a Stackelberg game, in which the private jammers and
the transmitter are the leaders and the follower of the game, respectively. A
fixed interference price scenario is considered first, in which a closed-form
solution is derived for the optimal amount of interference generated by the
jammers to maximize the revenue of the legitimate transmitter. Based on this
solution, the Stackelberg equilibrium of the proposed game, at which both
legitimate transmitter and the private jammers achieve their maximum revenues,
is then derived. Simulation results are also provided to validate these
theoretical derivations.
