Perfect Maximization of Transmission Content Using Utility Function

The authors study the degraded compound multi-receiver wiretap channel, which consists of two groups of users and a group of eavesdroppers. They consider two different communication scenarios. In both scenarios, the transmitter sends two confidential messages, one for each group of users. In the first scenario, both messages need to be kept confidential from the eavesdroppers. For this scenario, they assume that there is only one eavesdropper. They obtain the secrecy capacity region for general discrete memory less channel model, the parallel channel model and the Gaussian parallel channel model. For the Gaussian Multi-Input Multi-Output (MIMO) channel model. They obtain the secrecy capacity region when there is only one user in the second group.
