Enhancing Network Security Strategies against External Threats to Civil Aircraft
Quanxin Cao, Linfang Yan, Chen Bin, Fan Chenchen · 2016
To satisfy frequent pilots' requirements to access network and data on board, connections from public network domain to flight control network domain even airborne electronics were enabled recently in civil aircrafts. These services change the civil aircraft airborne electronic system from an isolated information island to an open cyberspace, which is vulnerable to new external threats from public network. Some regulations or specifications were raised to prevent threats, such as RTCA DO-326 specification However, practical implementation or evaluations were not reported. In this paper, It was proposed a set of strategies to implement civil aircraft aviation network security technology integration. According to the strategies, It was proposed an algorithm to reduce the impact of external network threat on the safety of the flight. Theoretical analysis based on Nash equilibrium validates the correctness of our strategies and algorithm.
