A method and system for unmanned aerial vehicle formation network security communication

Abstract

Embodiments of the present invention provide a method and system for safe communication in a UAV formation network. Wherein, the method includes: based on the channel information between the UAV group and multiple terminals and the transmission power set of the UAV group, obtaining the confidentiality and rate of the UAV group; adjusting the transmission power set to maximize the Confidentiality and rate, and the transmission power set when the confidentiality and rate is maximum is used as the target transmission power set of the drone group, so that the drone group follows the target transmission power set and the several Authorize the terminal to communicate. In the method and system provided by the embodiments of the present invention, the target transmit power set is obtained by adjusting the transmit power set to maximize the confidentiality and speed, so that the UAV group communicates with several authorized terminals according to the target transmit power set, ensuring information transmission The security of the network improves the security of the UAV formation network communication.

Description

technical field [0001] The present invention relates to the technical field of information security, in particular to a method and system for safe communication in a UAV formation network. Background technique [0002] In recent years, due to the advantages of small size, low cost and easy deployment, UAVs have been widely used in the field of wireless communication. It can be applied in many aspects of mobile communication, such as mobile coverage, mobile relay and mobile data collection. At present, in some emergency situations, such as public security, logistics, and forest fire monitoring, the cooperative communication method of UAV formation is also receiving more and more attention. It is very important to meet the performance requirements between multi-UAV and 5G communication. played an important role. [0003] With the widespread application of UAVs in public, civil and military applications, the security issues in UAV communication have also received more and mor...

Problems solved by technology

One of the outstanding challenges in the field of wireless communication for UAVs is the problem of secure transmission of information. Due to the inherent openness of wireless communication channels, the broadcasting of radio signals and the dynamics of UAV communication network topology, it is easy to cause information transmission Leakage and eavesdropping in the process, thus posing a threat to the communication security of drones

Although the existing encryption methods and technologies have played a certain role in the security of UAV communication, such as the traditional key-based encryption method and the physical layer security technology based on the physical characteristics of wireless channels, etc., due to the UAV formation network Due to the complexity of the dynamic topology, the communication security of the UAV formation network is still not guaranteed
