AI Technical Summary

Technical Problem

Existing low-altitude aircraft authentication schemes are computationally complex and have high latency. Furthermore, they are prone to leaking the privacy data of legitimate aircraft during the tracing of malicious aircraft, making it difficult to meet the real-time and security requirements of low-altitude economic scenarios.

Method used

An anonymous authentication method based on pseudonym aggregation index is adopted. By constructing pseudonym aggregation values ​​and using their hash results as indexes, index-level identity authentication and privacy protection traceability are achieved. Authentication request processing is carried out using additive homomorphic encryption, and the mapping relationship between pseudonym aggregation index and real identity identifier is stored on the blockchain.

Benefits of technology

It reduces authentication latency, decreases computational overhead, and improves system security, enabling anonymous communication under normal circumstances and privacy-preserving traceability under malicious circumstances, thus balancing efficient authentication and safety supervision of low-altitude aircraft.

Abstract

The application discloses an aircraft anonymous authentication method based on pseudonym aggregation index, and the method constructs a hierarchical collaborative architecture of a trusted authority center, a regional management agency, a low-altitude base station and an unmanned aircraft, completes system initialization, strong authentication and key negotiation based on an elliptic curve cryptography system, generates an aircraft pseudonym by the regional management agency, and generates a unique index through aggregation operation, and the index is chained together with a certificate, and the trusted authority center stores the mapping relationship between the index and the real identity. The aircraft initiates an anonymous authentication request through additive homomorphic encryption, and the index level fast authentication is completed by a calculation node after verification by the base station; in a malicious scene, the ciphertext pseudonym is aggregated, and the real identity is traced back by controlled decryption of the trusted authority center, and the whole life cycle management of the certificate is realized, forming a 'one-time strong authentication and multiple fast authentication' mode. The method reduces authentication complexity and time delay, improves high-concurrency processing capacity, and realizes privacy protection and security supervision.
