Information Security Architecture Design for Cyber-Physical Integration System of Air Traffic Management

With the continuous expansion of air traffic flow, increasingly serious aviation network security threats have a significant and far-reaching impact on safe operation industry. The networked management (ATM) system is an integrated space–air–ground integrating communication, network, satellite, data chain technology, which adopts network-centric structure to provide network-enabled services applications for transportation system. In view faced by ATM, this paper studies basic theories key technologies ATM information assurance designs credible architecture comprehensive systematic ATM. Starting from problems development trend assurance, investigates dynamic complex processing process system, analyzes interaction between its cyber physical then constructs cyber–physical fusion model threat model. Furthermore, causal relationship alert mapped into Bayesian game proposed using Nash equilibrium strategy. At last, based blockchain technology formed establishing distributed co-trust mechanism multi-chain storage structure. We expect bring some inspiration related research in academia so as useful reference construction safety technology.
