Embodiment Construction

[0040] The present invention will be further described in detail below in conjunction with accompanying drawings and examples.

[0041] There have been many studies on the security of IMA dynamic reconfiguration, such as human factors, etc., but the configuration process of IMA dynamic reconfiguration is very complicated, and it is difficult to evaluate its security. In the process of describing embedded systems, AADL has a very wide range of applications in modeling embedded systems to describe their reliability and security. Therefore, the present invention uses AADL to model the dynamic reconfiguration process, so as to visualize the complex dynamic reconfiguration process and facilitate security analysis. The purpose of proposing this modeling method is to further analyze the security constraints on this basis.

[0042] The invention proposes a language modeling method for the IMA dynamic reconstruction process. First, after decomposing and simplifying the abstract dynam...

Abstract

The invention discloses an AADL based IMA dynamic reconfiguration modeling method used for avionics system security modeling. The method comprises: determining dynamic reconfiguration process elements, decomposing a dynamic reconfiguration process into sub-states, and determining trigger and conversion actions required for conversion between each state configuration situation and a state; representing software and hardware constitution of IMA by utilizing ARINC653 accessories, describing the dynamic reconfiguration process by utilizing behavior accessories, describing a trigger behavior by utilizing error model accessories, and representing different configuration situations of the dynamic reconfiguration process by utilizing modes; determining IMA dynamic reconfiguration process model instances; describing a dynamic reconfiguration conversion process by utilizing combination of the AADL behavior accessories and the modes; and realizing and perfecting an established model by utilizing software. According to the method, the complicated dynamic reconfiguration process is modeled, so that the security of the dynamic reconfiguration process can be conveniently analyzed; and a brand-new process modeling method is constructed by combining a mature AADL language with the IMA dynamic reconfiguration process.
