The invention provides a two-way communication system and method between an avionics network domain and an information network domain in order to effectively solve the problems of safety isolation andflow direction protection of two-way communication between the avionics network domain and the information network domain in an airborne environment. According to the invention, the avionics networkaccess control unit, an information network access control unit and a communication control management unit are arranged in the network domain boundary control device of the airborne information network; a, Modules communicating with high-security-level applications are deployed in an avionics network access control unit. Modules communicating with low-security-level applications are deployed in an information network access control unit. and the modules run in an isolated manner, so that the problems of safety isolation and flow direction protection of bidirectional communication between theavionics network domain and the information network domain in an airborne environment can be effectively solved, and a solution is provided for bidirectional safety communication between the civil airborne information network and the avionics network.
Description
technical field [0001] The invention relates to a bidirectional communication system and method between the avionics network domain and the information network domain. Background technique [0002] In the aviation field, high-safety applications running in the avionics system provide a guarantee for the normal operation of the entire aircraft. In the traditional electronic system of the aircraft, the avionics data is transmitted in a closed airborne environment through the avionics network (such as avionics full-duplex switched Ethernet), and will not be attacked by external information security, ensuring the security of the avionics data. safety. With the large-scale application of information technology in civil avionics systems, in order to provide more and more convenient services to aircraft operators, aircraft designers have introduced Ethernet-based on-board information service systems, through the residency and operation of low security Hierarchical applications im...
