The Information Assurance Of Air Traffic Management System Based On SSE Theory

The Air Traffic Management (ATM) system is an open and complex intelligent system, which links the infrastructures and technologies of aeronautic communication, navigation, surveillance, and automation together to provides aeronautic information, aeronautical meteorology, and air traffic control (ATC) services to the airport, airlines, and aircraft. The targets of ATM system are enabling safe, orderly and efficient aircraft operations.An approach of information Assurance for ATM system based on Systems Security Engineering (SSE) theory is proposed in this thesis. The innovations in this thesis are as follows.(i) The model of security evaluation for information assurance of ATM system based on the theory of Dynamic System Control (DSC). This thesis established the theory of security evaluation for ATM system from the three views of function, operation, and attribution. The security indicator for information assurance of ATM system is proposed based on the security baseline policy. This theory is composed of security evaluate model based on DSC theory for the purpose of determine the security level of ATM element.(ii) The method of security evaluation for ATM system based on Artificial Neural Network. This thesis application of integrated decision making in ATM system based on grey correlation theory to solve the fuzzy relationship among a lot of complicated factors in ATM system. The security evaluation method of ATM system based on improved BP and RBF model of Artificial Neural Network (ANN) is proposed in this thesis. Test result shows that the proposed method meets the requirements of ATM information security and efficient to the information assurance of ATM system.(iii) The secure approach of operational data in ATM system based on Security Access Path (SAP). The thesis proposes a database secure access approach of operational data in ATM system based on SAP, which could effectively identify users, carry access control, and resist kinds of attacks with the uniform authentication based on diameter.Experiments on information security of ATM system with practical operation data of ATM system have conducted. Result shows that the proposed approach in this thesis is effectively.
