N2  - In order to improve safe operation abilities of aircraft in networked environment, and address problems of unintended risks caused by fragmentation of functional safety assessment and information security analysis of existing avionics system of civil aircraft, based on dual " V" model of civil aircraft system' s security analysis, with mapping relationship between functional failure status category and information security threat status level as an integration point, correlation between integrated safety analysis activities and avionics system development process was analyzed with information security risk being taken as a new cause factor for functional abnormalities in combination with current safety assessment process. The, an integrated analysis method of airborne avionics system ' s functional and cyber security was proposed. The results show that the method has obvious differences in five aspects, such as concerns and risk attribution, and it considers impacts of functional safety and information security on aircraft, crew and passengers, and integrates analysis of functional safety and information security at each link of double "V" model, so as to effectively improve integrated functional safety and information security of avionics system. © 2022 China Safety Science Journal.
