A secret communication system via SD-SMSE

Setting up a communication system should also pay attention to both security and concealment in addition to the validity and reliability of the information, especially in military communication. In this paper, we introduce an application of the SD-SMSE framework under the secret communication, and the application combines overlay and underlay access with encryption. At the receiving end, we use the received key to restore the original information from the received encrypted information. The simulation results approve the feasibility of the framework under the given new application, which improves the utilization of spectrum and ensures the security of communication.
