Multi-unmanned system mutual authentication method based on data distribution service

By adopting mutual authentication methods based on data distribution services in multiple unmanned systems, the agent can independently complete identity authentication when disconnected from the ground control station, solving the problem of unstable cooperative relationships in complex task environments, and improving the system's destructive resistance and task continuity.

AI Technical Summary

Technical Problem

In existing multi-unmanned systems, when the agent communicates with the ground control station interrupted or offline, it cannot complete the identity authentication between the agents, resulting in unstable cooperative relationships in complex task environments.

Method used

The mutual authentication method of multiple unmanned systems based on data distribution services is adopted, and by broadcasting the acquisition request of security parameters, multiple security parameters are received, virtual public keys are calculated, and the group public keys are compared to the public keys, identity authentication between agents is realized.

Benefits of technology

When the agent is disconnected from the ground control station, the agent can independently complete identity authentication, ensuring that multiple unmanned systems maintain reliable cooperative relationships in complex task environments, greatly improving the system's destructive resistance and task continuity.

Abstract

The invention belongs to the technical field of mutual authentication of multiple unmanned systems, and discloses a data distribution service-based mutual authentication method for multiple unmanned systems, which comprises the following steps of: when a connection request of an intelligent agent to be authenticated is received, broadcasting an acquisition request of a security parameter to a communication range; t-1 safety parameters are received; calculating a virtual public key based on the t-1 security parameters and the security parameter of the current agent; when the virtual public key is the same as the group public key, a communication secret key is sent to a to-be-authenticated agent, and the to-be-authenticated agent is added into a communication list; according to the invention, the virtual public key is calculated based on the security parameter, and the virtual public key is compared with the group public key, so that the identity authentication of the agent to be authenticated is carried out, the problem that the identity authentication of the agent cannot be completed in a network interruption or offline scene in the prior art is solved, and an important technical guarantee is provided for the application of multiple unmanned systems in multiple fields.
