AI Technical Summary

Technical Problem

In collaborative operations involving multiple drones, the communication process lacks effective security guarantees, and data is easily eavesdropped on and tampered with. Attackers may impersonate drones to send false information or launch denial-of-service attacks, leading to deviations in mission decision-making. Furthermore, drones have limited computing power and insufficient battery power, resulting in inadequate security, efficiency, and scalability of the communication solution.

Method used

An identity signature mechanism is adopted. The drone status list is initialized through the key generation center, and the drone private key and shared key are generated. By combining elliptic curve cryptography and hash function, ciphertext fields are constructed and assembled into ciphertext. The ground station performs timestamp freshness and parameter validity checks to achieve identity authentication and data encryption, resist denial-of-service attacks, and support dynamic member management and batch verification.

Benefits of technology

It achieves highly secure and efficient communication between drones and ground stations, can dynamically manage drone crew members, resist attacks, and reduce computing and power consumption, making it suitable for drone platforms with limited computing power and power.

Abstract

This invention discloses a secure communication method and system between a drone and a ground station. The method includes: a key generation center acquiring system parameters and initializing a drone status list; receiving a registration request and determining the drone's target key parameters; sending a portion of the target key parameters to the drone, writing the remaining portion into the drone status list, and updating it to the ground station; the drone signing the message to be sent and constructing ciphertext fields to assemble ciphertext and sending it to the ground station; the ground station receiving the ciphertext, performing timestamp freshness checks, parameter validity checks, and drone status list matching to obtain pre-filtered ciphertext and its corresponding session key, decrypting it to obtain the plaintext message, and verifying the validity of the signature corresponding to the plaintext message; if the signature is valid, the plaintext message is output; if the signature is invalid, the ciphertext is discarded. This method enables highly secure, efficient, and dynamically manageable drone-to-ground station communication.
