In drone-assisted communication scenarios, especially in post-disaster rescue, there is a risk of privacy leakage when heterogeneous drone groups collaborate. Therefore, ensuring the anonymity of drones while guaranteeing the reliability of the message source is a significant challenge. Although existing schemes achieve anonymity, they are unable to dynamically adjust the authentication difficulty according to changes in the physical environment. In this paper, we propose an application of multi-factor puf authentication circuit based on lattice group signature for in drone-assisted communication. The scheme innovatively designs a PUF-based multi-factor authentication circuit and proposes a dynamic authentication strategy, achieving authentication and physical security under different security requirements. The scheme proposes a lattice-based heterogeneous drone group signature scheme through Merkle hash tree and lattice cryptography, which achieves efficient anonymous authentication and group member update and ensures post-quantum security. The security of the scheme is proved by formal security analysis based on AVISPA and random oracle model (ROM). Moreover, experimental results show that PUF-CLGS outperforms the benchmark schemes in terms of both computational and communication costs.
