Embodiment Construction

[0048] The present invention retains the goal of "providing subscription-based services" in the ADBP protocol and the characteristics of using XML language for transmission. Aiming at the characteristics of avionics data and the security requirements of avionics networks, it redefines the attributes of metadata and increases the number of applications Register and application logout operations to realize authentication and authorization of customer applications, add application heartbeat monitoring operations to realize health status management of communication links, and add signature value fields to messages to realize message authentication, and add CRC checks to realize message data Integrity protection, thus providing guarantee for the safety and security of avionics data communication.

Abstract

In order to solve a communication problem between networks of different safety grades in an airborne network and meet the safety and the environment-friendly needs of the data (such as aviation data) in the high-safety network in an application transmission process, the invention provides an aviation data service communication method for an airborne network service system. According to the method, subscription-based service is provided by an ADBP protocol and XML language is adopted to perform transmission, attributes of element data are re-defined according to the characteristics of the aviation data and the security needs of the aviation network, application register and application cancellation are increased to realize authentication and authorization to client application, so that the health state management of the communication link is realized by increasing operation of monitoring through heartbeats, information identification is realized by adding signature value field in the information, protection to data complexity of the information is realized through CRC examination, and the aviation data communication safety and security are guaranteed.

Description

technical field [0001] The invention relates to an avionics data service communication method of an airborne network service system, which involves improving the Avionics Data Broadcast Protocol (ADBP for short) formulated by ARINC834. Background technique [0002] ARINC811 (Commercial Aircraft Information Security Concepts of Operation and Process Framework) defines a new generation of aircraft systems. Among them, the aircraft system is divided into three network domains: aircraft control domain, aviation information domain, and passenger information / entertainment system domain. These three network domains have different levels of security, with the aircraft control domain having the highest level of security, followed by the aviation information domain and the passenger information / entertainment system domain being the lowest. However, with the development of civil aviation, the information in the three domains is inevitably connected to each other: the internal connecti...
