Embodiment Construction

[0045] The content of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0046] Aiming at the fuzzy testing of the avionics interface data communication protocol (AIDCP protocol), the present invention designs a parameter-based fuzzy testing method for the avionics interface data communication protocol, which is used for the fuzzy testing of the avionics interface data communication protocol in the airborne information network. Fuzz testing realizes the robustness evaluation of avionics interface data communication protocol products and fills this gap.

[0047] The method of the invention includes three processes: a main process, a sending process and a monitoring process. Among them, the main process starts first and keeps running. During the running of the main process, start the sending process and the monitoring process according to the running time, and exchange information with them. ...

Abstract

The present invention relates to a fuzzy testing method of avionics interface data communication protocol based on parameters, which solves the problem of robustness testing of avionics interface data communication protocol, which includes a main process, a sending process and a monitoring process, and the main process includes the following steps: Step 1 , Determine whether the user structure tree has special requirements; if not, go to step 2, if yes, go to step 3; step 2, call the default structure tree, go to step 4; step 3, create a new structure tree, and call the newly generated Structure tree, enter step 4; step 4, call the protocol parameter mutation algorithm, and assign values ​​to the parameters in the structure tree to be used; step 5, initialize the shared data; step 6, assign values ​​to the shared data according to the running state: step 7, Start the sending process and the monitoring process; Step 8, wait for the notification parameters from the sending process and the monitoring process; Step 9, if the notification parameters are received, return to Step 6, if not, return to Step 8.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a parameter-based fuzzy testing method for an avionics interface data communication protocol, which is used for fuzzy testing the avionics interface data communication protocol in an airborne information network. Background technique [0002] With the development of airborne information technology, the avionics interface data communication protocol is applied to the communication between airborne applications. It is an application layer protocol, built in the aviation Ethernet communication based on the TCP / IP protocol stack. This protocol is mainly used to provide aircraft parameters for applications connected on the aviation Ethernet interface for status monitoring, fault analysis, maintenance and statistics. [0003] The robustness of the protocol is the guarantee for the successful operation of the protocol and related functions. However, because the proto...
