Security Service Combination System for Civil Aircraft

Abstract

The invention discloses a civil aircraft oriented security service combination system and mainly solves the problem that in the prior art, a business process is low in security. The system comprises four subsystems. An airborne database subsystem is used for storing airborne service serial numbers, airborne service names, QoS function attribute values and QoS security protection risk attribute values and providing query service for an airborne service discovery subsystem. The airborne service discovery subsystem is used for selecting airborne service sets with specific functions from the airborne database subsystem and outputting the airborne service sets to an airborne service selection subsystem. The airborne service selection subsystem is used for selecting airborne service with the lowest security protection risk value from each airborne service set and outputting the airborne service to an airborne service arrangement subsystem. The airborne service arrangement subsystem is used for arranging the airborne service provided by the airborne service selection subsystem. According to the system, under the condition of satisfying function demands of a civil aircraft, the security ofthe business process of a civil aircraft information system is improved.

Description

technical field [0001] The invention belongs to the technical field of information security, and in particular relates to a security service combination system, which can be used in an airborne information system of a civil aircraft. Background technique [0002] With the advancement of technology, electronic information systems will be widely used in civil aircraft, and real-time exchange and update of flight data, voice data, video data and other on-board electronic data will be realized. In civil aircraft using electronic information systems, many airborne services, including security services, are responsible for realizing the real-time exchange and update of on-board electronic data. According to the different internal security levels of electronic aircraft, airborne services are divided into four domains: control domain, information and service domain, information and entertainment service domain, and passenger equipment domain. In the control domain and information a...
