Abstract

The present invention provides a data security analysis method for avionics systems. The method comprises: establishing a data-driven system model; identifying security related data according to the system model; establishing a data supply chain model of the security related data; carrying out data hazard mode analysis, and hazard and operability analysis according to the data supply chain model;and according to analysis results, obtaining and evaluating the data hazard control technology. According to the method provided by the present invention, static and dynamic problems of the data in the avionics systems can be discovered, and hazards brought by the data can be discovered in advance, so that system security can be improved, casualties and property losses are avoided, and the methodis applicable to military and civilian avionics systems.

Description

technical field [0001] The invention relates to the technical field of safety research of avionics systems, in particular to a method for analyzing data safety of avionics systems. Background technique [0002] At present, data-intensive systems are more and more widely used in real-time computer systems, especially in avionics systems, where data can be used to describe static descriptions of the environment such as navigation data and aircraft performance data; modern avionics system applications use a large number of Standardized software and hardware units, such as COTS products, often implement specific functions through configuration data; and changes in the external environment of the system will also generate a large amount of dynamic data. But a new problem has emerged: the safe operation of avionics systems is increasingly dependent on data. The avionics system has a large amount of data and various types, the description objects are complex and diverse, the data ...
