Blind Identification of Communications Networks in Service Layer

One of the major challenges in electronic and cyber warfare is to achieve maximum information from the intercepted signals of a communications network. To this aim, the first step is reverse engineering of the physical and data transmission layers in order to obtain the transmitted packets. In the next step, service layer should be identified. In this step, the exact meaning of each packet along with the communications state machine should be identified. By completing these tasks, the information content exchanged through the network would be available. In this paper, a comprehensive scheme is proposed for identification of the service layer. With the intention of proving proficiency of the proposed scheme, usability of this scheme for identification of nine different standards, including GSM, LTE, HSDPA, DVB-S2, FLEX,
