Embodiment Construction

[0032] In the integrated avionics system, each call to system services or access to system resources must be authorized to ensure that only calls or access that comply with the control strategy can be performed. The access control based on the trusted access control system ensures the controllability and security of the application partition's access to system services and system resources, prevents malicious code from leaking sensitive information, and provides a strong guarantee for the credibility of the integrated avionics system. The access control model based on the trusted access control system draws on the ideas of the Bell-LaPadula (BLP) model and the BIBA model, considers the issues of confidentiality and integrity, and establishes a trusted authorization strategy.

[0033] according to figure 1 Concrete method of the present invention is described:

[0034] The steps of the trusted access control method are as follows:

[0035] 1) Build a trusted access control sy...

Abstract

The invention belongs to the information security technology field of a comprehensive avionics system, and particularly relates to a trust access control method for the comprehensive avionics system. The method comprises the following steps: firstly constructing a trust access control system; then carrying out access control of the comprehensive avionics system on the basis of the trust access control system. Through the method disclosed by the invention, the controllability and security of application partitioning for system service and system resource access are guaranteed, malicious codes are prevented from leaking sensitive information, and a powerful safeguard is provided for the credibility of the comprehensive avionics system.

Description

technical field [0001] The invention belongs to the technical field of information security of an integrated avionics system, and in particular relates to a trusted access control method for an integrated avionics system. Background technique [0002] Aviation information security is one of the most challenging issues in the integrated avionics system. Strengthen the active defense level of the airborne embedded system, build and improve the security system of the integrated avionics system, protect the equipment system from external threats and improve The invulnerability of aviation equipment systems is of great significance and has attracted widespread attention at home and abroad. In a highly integrated avionics system, resources are highly shared, data is highly fused, and software is highly intensive. Different levels of tasks share a unified hardware platform, which brings major hidden dangers to the safety and reliability of aircraft. Contents of the invention [...
