Block chain-based 5G unmanned aerial vehicle cross-domain identity authentication method, system and terminal

Abstract

The invention discloses a 5G unmanned aerial vehicle cross-domain identity authentication method and system based on a block chain, and a terminal, and relates to the technical field of unmanned aerial vehicles, and the key points of the technical scheme are as follows: initiating a transfer transaction with additional information as a communication connection request; sending an identity authentication request to an alliance chain according to the communication connection request; the alliance chain calls a built-in intelligent contract to search access control information and a registration validity period of domain A equipment according to the identity authentication request; performing hash processing on an identity label in the account information to obtain a second hash value, and matching the second hash value with the first hash value; and the domain B equipment performs session key negotiation with the domain A equipment according to the legal identity information and then establishes communication connection. According to the invention, the identity authentication of the cross-domain unmanned aerial vehicle in the distributed environment is realized by using the multi-signature intelligent contract, only one transaction needs to be submitted to the block chain for one-time authentication, and compared with a traditional authentication mode using a digital certificate, the identity authentication is completed with smaller communication overhead.

Description

technical field [0001] The present invention relates to the technical field of unmanned aerial vehicles, and more specifically, it relates to a blockchain-based 5G unmanned aerial vehicle cross-domain identity authentication method, system and terminal. Background technique [0002] UAV is an unmanned remote control aircraft controlled by wireless induction remote control equipment or self-contained program control device. According to the application field, it is divided into military and civilian use, and can be used in scientific research, site exploration, military, leisure and entertainment purposes. In recent years, UAVs have grown significantly in the global market and are widely used in construction, oil, gas, energy, agriculture, disaster relief and other fields. [0003] With the development of wireless communication technology, the 5G era has arrived. 5G technology is a new generation of cellular mobile communication technology that can provide low-latency, high-...

AI Technical Summary

Problems solved by technology

However, the 5G environment is an open network environment, facing various security threats, and unreliable communication links may lead to sensitive data leakage, so identity authentication is particularly important

In view of the mobility of UAVs and the heterogeneity of UAV networks, traditional authentication methods based on passwords or user names cannot meet the authentication security requirements in a distributed environment.

At the same time, if the single-node identity authentication server fails, the service will be paralyzed

In addition, drone missions may require the cooperation of multiple companies. How to safely and effectively collaborate drones across enterprise domains has become a major problem, and how to establish a security responsibility mechanism needs to be resolved urgently.
