Unmanned aerial vehicle access control method based on attribute authentication

Abstract

The present invention discloses an access control method based on attribute authentication in a multi-UAV scene and mainly solves the problem that the unmanned aerial vehicle (UAV) communication system in a complicated environment cannot be controlled in the existing technology. The technical scheme of the present invention is as follows: firstly, a UAV communication network consisting of four parts: a satellite, an Airborne Early Warning Aircraft (AEW), a UAV and a ground station is initialized; secondly, when the UAV enters a certain aircraft group, the UAV sends registration information and attribute certificates to the AEW in the current aircraft group to complete the attribute authentication; and thirdly, the UAV sends a data access request to a satellite main body in the range of the current aircraft group to complete the authorized access to satellite data. The UAV of the present invention uses its own attributes as the basis for aircraft group join and data access so as to realize the flexible fine-grained access control. When the UAV accesses the satellite data, the UAV only needs to show attribute sets to realize the anonymous access to the satellite data and ensure the communication safety for the UAV system. The method provided by the invention can be used for authentication and access in the multi-UAV scene.

Description

technical field [0001] The invention belongs to the technical field of information security, and in particular relates to a UAV access control method, which can be used for authentication access in a multi-UAV communication scenario. Background technique [0002] UAVs with autonomous flight capabilities can be used to perform tasks such as aerial photography, surveying, autonomous reconnaissance, and automatic attack. They have a wide range of applications and scientific research value, which also makes them a research hotspot for scientific research institutions in many countries around the world. In the entire UAV autonomous system, the communication system is an important part of the flight control system, which is responsible for the collection and transmission of various flight status information and mission load data, so that the ground monitoring system can monitor the flight status of the UAV. , Complete the flight mission safely and reliably. [0003] On the basis ...

AI Technical Summary

Problems solved by technology

Since the main body of the communication system has many different types, its communication methods, data formats, security requirements, etc. are not the same, a large number of different users need to frequently interact with information, and have strict requirements on communication delay, the traditional Access control methods are not suitable for such a complex environment
