An identity-based UAV key management and networking authentication system and method

Abstract

The invention belongs to the technical field of devices for checking the identity or credentials of system users, and discloses an identity-based UAV key management and networking authentication system and method. The ground authentication server is responsible for generating and distributing UAVs for encryption. System parameters, identity information, and keys required for key management and network authentication; the UAV authentication client is the main body of the system; through mutual cooperation, the key pair for UAV network authentication can be generated in a distributed manner , and use the key pair to realize identity authentication and key agreement between UAVs. The present invention improves the problem of unequal node calculation in UAV network key management existing in the prior art, enhances the reliability of the system, and realizes UAV self-organized key management; Two-way authentication ensures the credibility and authenticity of both parties in the communication; using identity public key and bilinear pairing to achieve, the calculation overhead is less, and the implementation efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of devices for checking the identity or credentials of system users, and in particular relates to an identity-based UAV key management and networking authentication system and method. Background technique [0002] At present, the existing technologies commonly used in the industry are as follows: UAVs, as a member of modern air military forces, have the advantages of no casualties, few use restrictions, and good concealment, and they are playing an increasingly important role in modern warfare. status. The research on the confrontation of UAVs has become the focus of the research of various military powers today. With the complexity of the electromagnetic environment and the increasing trend of communication confrontation, the problems faced by drones in the process of information transmission such as deception, interference and eavesdropping by attackers have also become more serious.

AI Technical Summary

Problems solved by technology

The disadvantages of this invention are: first, it does not take into account the strong mobility of drones, and it is feasible for mobile drones to find multiple one-hop neighbor service nodes; second, the serial execution between service nodes The process of distributing keys can cause synchronization issues and high communication latency

[0004] (1) Existing technology-there are service nodes that provide trusted platforms in the network, and the computing inequality between common UAV nodes and service nodes. The service nodes undertake the main computing tasks, but the topology of the UAV network changes frequently. The service node cannot provide effective services

[0005] (2) The serial execution process of distributing keys between service nodes in the prior art will lead to synchronization problems and high communication delay, which is not suitable for deployment in UAV networks

[0007] There is a lack of infrastructure in the UAV network, and the topology changes frequently. The key management suitable for the UAV network must be completed by the UAV self-organization. Key Management Service

In addition, the computing power of the UAV is limited, and the wireless link is unstable. The communication overhead and computing overhead generated by the key management scheme need to be within the range of the UAV.
