Security Scheme of UAV Flight Control Based on Attribute Access Control Policy
The flight control system is the core component of unmanned aerial vehicles(UAVs),which plays a decisive role in the function and performance,and it is a crucial target for information security protection.In this paper,a location-and-environment oriented attribute-based access control(LE-ABAC)policy is designed to deal with the security risks of malicious code injection and internal interactive data tampering faced by PX4 flight control system.The access control policy,based on object entity attri-butes and external location environment information of the UAV,formulates corresponding rules that enable fine-grained control of the data exchange process within the UAV,protecting the confidentiality and integrity of crucial data exchanges.In the study,attack simulation experiments are conducted on the PX4 software simulation platform to verify the proposed scheme.Finally,the results show that the model can effectively protect the interactive data of the flight control system from theft and tampering with-out significantly reducing the efficiency of UAV flight control execution.
