Problems solved by technology

This also weakens the security of the ADS-B protocol, because any attacker equipped with an ADS-B receiver can listen to the message broadcast by the aircraft by modulating the frequency band to 1090MHz, thereby obtaining the aircraft's position, speed, etc. Sensitive information

Embodiment Construction

[0057] In order to describe the technical content, structural features, achieved goals and effects of the present invention in detail, the following will be described in detail in conjunction with the embodiments and accompanying drawings.

[0058] The invention proposes a solution to the confidentiality and integrity of the ADS-B protocol, which achieves good results in ensuring the compatibility of the generated ADS-B message with the original ADS-B protocol while encrypting and generating message verification codes . The schematic diagram of the overall process of the whole program is as follows: figure 1 shown, including steps:

[0059] We obtain the .avro file through the existing OpenSky open source project, which contains the original ADS-B message and other information such as the sensor number.

[0060] In the Java program, the reading and parsing of the .avro file can be realized by using the org.apache.avro interface. Read the rawADS-B message through the org.ope...

Abstract

The invention discloses a solution to the confidentiality and integrity of the ADS-B protocol, which belongs to the technical field of applied cryptography; a solution to the confidentiality and integrity of the ADS-B protocol includes a trusted third party to configure security parameters , The aircraft receives the security parameters and completes the encryption and sends the ADS‑B message, and the receiver receives the ADS‑B message for verification. The invention can realize the guarantee of the confidentiality and integrity of the traditional plaintext broadcast transmission message on the basis of being compatible with the current ADS-B protocol format.

Description

technical field [0001] The invention belongs to the field of aviation communication, and in particular relates to a solution for the confidentiality and integrity of the ADS-B protocol. [0002] Background of the invention [0003] Due to the unprecedented development of the aviation field in recent years, more and more people have begun to choose to take an airplane as a means of transportation for long-distance travel. At the same time, the rate of aviation accidents has also increased. For example, the recent Malaysia Airlines incident has aroused the attention of aviation safety around the world. [0004] The basic data format of ADS-B is as follows: figure 1 as shown, [0005] (i).DF (DownlinkFormat) field [0006] The length of the DF field is 5 bits, which is used to distinguish different downlink formats (DownlinkFormat). The value of DF can be 17, 18 or 19. DF=17 is used for S mode transponder to send ADS-B message; DF=18 is used for non-S mode transponder to s...
