A UAV-assisted terminal access authentication method, system, device and application

Abstract

The invention belongs to the technical field of communication network security, and discloses a UAV-assisted terminal access authentication method, system, equipment and application. The UAV-assisted terminal access authentication method includes: the terminal, the UAV through The secure channel interacts with the network control center to complete the registration; after both the UAV and the terminal are registered, the UAV performs access authentication; after the UAV access authentication is completed, the terminal performs access authentication with the assistance of the UAV ; When the UAV deviates from the designated airspace due to force majeure and the authentication is interrupted, multiple UAVs cooperate quickly to continue to assist the terminal to complete the access authentication. The invention can efficiently complete the authentication of different entity identities in real time with the assistance of UAVs, quickly establish a stable and reliable mobile communication network, and provide technical support for scenarios such as UAV emergency communication, military operations, fire rescue and so on; in realizing anonymity At the same time, it avoids the complicated certificate management process in the public key system and achieves stronger security capabilities.

Description

technical field [0001] The invention belongs to the technical field of communication network security, and in particular relates to a terminal access authentication method, system, equipment and application assisted by a drone. Background technique [0002] At present, with the popularization of 5G communication technology and the rapid growth of Internet of Things devices, people's demand for mobile communication services continues to increase. Satellite communication networks can be used to cover mountainous, ocean-going, and other areas, and at the same time cooperate with UAVs for collaborative operations. It provides technical support for the military, electric power, rescue and other fields. The space-ground integrated information network constructed thus greatly promotes the development of mobile devices in the direction of full-scenario collaboration and high-reliability interconnection, which is conducive to the realization of the global information network.

Problems solved by technology

[0006] (2) Regardless of whether it is a satellite or a UAV device, its communication links are open and the network topology changes dynamically, which may lead to attacks such as channel eavesdropping, message tampering, and replay during the communication process.

[0011] (3) UAVs have the characteristics of strong mobility and limited endurance. During the authentication process of the ground terminal through the UAV, if the UAV leaves its designated coverage area, the terminal will need to repeat the authentication process, resulting in additional The signaling overhead and computing overhead affect the authentication efficiency

[0012] (4) Both ground terminal equipment and UAVs may be subject to physical attacks. After the opponent captures them through physical attacks, they may obtain the secret information stored in their memory chips, thereby forging identities to participate in authentication, illegally obtaining private information and Various permissions

Specifically: in the above communication scenario, if an attacker can obtain the identity information or other authentication information of the entity to be authenticated by monitoring the open link, it will pose a threat to the security of the entity to be authenticated and leak the communication content

Second, if a lightweight authentication process cannot be implemented, a large number of authentication requests will cause excessive computing loads on drones and satellites, resulting in unresponsive situations, which will affect the implementation of the protocol
