Flight mission-oriented unmanned aerial vehicle block chain establishment method, system, device and terminal

Abstract

The invention belongs to the technical field of unmanned aerial vehicles, and discloses a flight mission-oriented unmanned aerial vehicle block chain establishment method, system, device and terminal, and the flight mission-oriented unmanned aerial vehicle block chain establishment method comprises the steps that a ground control station establishes a task-oriented block chain; the ground control station manages the unmanned aerial vehicles to join the cluster; the ground control station manages the departure of the unmanned aerial vehicles from the cluster; and establishing end-to-end communication in the members of the unmanned aerial vehicle group. According to the invention, the block chain technology is applied to the unmanned aerial vehicle system, and the ground control station establishes a flight task-oriented block chain, so that the ground control station establishes unmanned aerial vehicle group task planning, group key management and end-to-end communication in the unmanned aerial vehicle group; the unmanned aerial vehicle information and the group key recorded in the block chain are difficult to counterfeit or tamper by utilizing the non-tampering characteristic of the block chain, so that the group key is safely distributed when the unmanned aerial vehicle joins or leaves, the trust relationship among unmanned aerial vehicle members is enhanced, and the end-to-end communication safety among the unmanned aerial vehicle group members is realized.

Description

technical field [0001] The invention belongs to the technical field of unmanned aerial vehicles, and in particular relates to a method, system, equipment, and terminal for establishing a block chain of an unmanned aerial vehicle oriented to flight tasks. Background technique [0002] In recent years, with the improvement of the level of science and technology, unmanned aerial vehicles that integrate information technology, computer technology and communication technology have become an important development target of various countries at present and in the future. It is widely used not only in the military field, but also in various aspects such as agricultural production, disaster warning, remote sensing and telemetry, and aerial photography. The existing UAV system mainly includes two parts: UAV swarm and UAV ground control station. Among them, the ground control station is the command center of the entire UAV system, which is mainly responsible for the management and mis...

Problems solved by technology

[0003] Through the above analysis, the problems and defects of the existing technology are: the safety performance of the existing UAV system is low, and the communication information in the UAV system has the risk of illegal monitoring or tampering, which leads to the sensitive mission information of the fleet (such as aerial photography) Geographical surveying and mapping data, command data for coordinated operations, etc.) leakage or tampering, threatening national defense and military security

[0004] The difficulty in solving the above problems and defects is as follows: firstly, how to reliably distribute group key management in UAV groups with unstable communication links, specifically including group member dynamic changes (group members join or leave) update group key, and how a drone with a lost communication link can safely recover the lost group key broadcast message for historical group communication erasure
