Problems solved by technology

In addition, if the messages sent by the air force aircraft equipped with the ACARS system are intercepted by the enemy during the execution of the mission, it may bring devastating consequences to the execution of the mission
After the "9.11" incident, various countries have paid more attention to anti-terrorist attacks. However, if the ACARS data link is attacked or used by terrorists, it will have a huge impact on national security.

Embodiment Construction

[0021] 1. According to figure 1 In the simulated system architecture, click the route management module on the onboard CMU to start, and the aircraft starts to fly.

[0022] 2. Pretend to be a legal DSP on the attack end and send a message to the aircraft, click the entity disguise icon on the attack end, enter the content of the message in the pop-up interface, and enter the network statistics report request with the label (Label) S1.

[0023] 3. Click Send to start sending information to the aircraft by pretending to be a ground terminal.

[0024] 4. In the CMU module, it can be seen that the CMU has received the request normally and responded.

[0025] 5. The network statistics report has been intercepted on the attack side.

Abstract

An aircraft communication addressing and reporting system (ACARS) data chain belongs to a wireless network, and compared with a wired network, the ACARS data chain is easily attacked. ACARS information is completely transmitted in a plaintext mode, and safety is insufficient. The invention provides a safety penetration testing method of the ACARS data chain. Entity impersonation attack is imitated mainly according to security holes existing in the ACARS data chain. In an ACARS system, an entity is easily disguised as a digital signal processor (DSP) terminal, space communication is destroyed, and normal operation of the ACARS system is blocked, and major accidents such as an aircraft crash are even caused. According to the safety penetration testing method of the ACARS data chain, a computer is disguised as a DSP through simple assembly, and sends an illegal control message to an aircraft in the air, a skyborne terminal can not detect legality of the illegal control message, and thus the illegal control message is responded. According to the technical scheme, safety loopholes of the ACARS data chain can be found out, and the safety penetration testing method of the ACARS data chain plays an active part in protection of safety of the ACARS data chain.

Description

technical field [0001] The present invention relates to an aviation VHF data link security technology, especially for the penetration test of the entity masquerade attack on the aircraft communication addressing and reporting system (Aircraft Communication Addressing and Reporting System, ACARS) data link, which can deeply dig out the potential safety hazards of ACARS , Play an active role in ensuring the security of the ACARS data link. Background technique [0002] ACARS is an acronym for ARINC Communications Addressing Reporting System. The system is designed to reduce voice communication requirements by automatically reporting aircraft arrival and departure times and other mission flight data. The system uses a designated airborne VHF frequency to transmit and receive data from an identically equipped ground station. [0003] ACARS is now operating smoothly day in and day out in commercial aviation around the world. The civil aviation system uses the ACARS system for ...
