Embodiment Construction

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

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

[0047] The method of the present invention includes three processes: the main process, the sending process and the monitoring process. Among them, the main process starts first and runs all the time. During the running of the main process, the sending process and the monitoring process are started according to the running time, and information is exchanged with them. Duri...

Abstract

The invention relates to a parameter-based fuzzy test method for an avionics interface data communication protocol, which solves the robustness test problem of the avionics interface data communication protocol. The method comprises a main process, a sending process and a monitoring process, wherein the main process comprises the steps of 1, judging whether a user structure tree has special requirements or not, if not, entering the step 2, and if so, entering the step 3; 2, calling a default structure tree, and entering the step 4; 3, forming a new structure tree, calling the newly generated structure tree, and entering the step 4; 4, calling a protocol parameter variation algorithm, and assigning values to parameters in the to-be-used structure tree; 5, initializing the shared data; 6, assigning values to the shared data according to the running state; 7, starting the sending process and the monitoring process; 8, waiting for notification parameters from the sending process and the monitoring process; and 9, if the notification parameters are received, returning to the step 6, and if not, returning to the step 8.

Description

Technical field [0001] The invention belongs to the field of communication technology, and specifically relates to a parameter-based fuzzing test method for an avionics interface data communication protocol, which is used for fuzzing an 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 aviation Ethernet communication based on the TCP / IP protocol stack. This protocol is mainly used to provide aircraft parameters for applications connected to the aviation Ethernet interface for condition 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 this protocol is a unique...
