A PUF‐based lightweight authentication and key agreement protocol for smart UAV networks

Li Zhang, Jianbo Xu, Mohammad S. Obaidat +2 more

Abstract With the advancement of information technology and the reduction of costs, the application of unmanned aerial vehicle (UAV) has gradually expanded from the military field to the industrial field and civilian field. It brings great convenience to people in surveillance, detection, transportation, emergency rescue etc. However, UAVs usually work in harsh natural environments, and their communication security confronts various challenges. Due to UAVs' limited resources, such as computing capability, storage space, and energy, traditional security protection schemes based on complex cryptographic algorithms are not suitable for UAV systems directly. Therefore, a two‐stage lightweight identity authentication and key agreement protocol for UAV is proposed in this paper. The entire process only uses hash and XOR operations, which significantly improves the authentication efficiency. Simultaneously, the physical unclonable function (PUF) is introduced and embedded into the UAV hardware to ensure UAV network communication security when a UAV suffers a physical capture attack. In the paper, the security of the proposed protocol is proved with Burrows–Abadi–Needham (BAN) logic, Real‐or‐Random (ROR) model, and AVISPA simulation tools. An informal security analysis is also provided to illustrate that the protocol satisfies the security requirements of UAV networks. Finally, the protocol is compared with other existing protocols regarding function properties, computation cost, and communication cost, which shows that the proposed protocol has effectiveness and practicality.

A Quantum-Resistant Authentication and Key Agreement Protocol for UAV Networks

Kaifeng Wu, Zhenhu Ning, Jiakai Dou +2 more

The unmanned aerial vehicle (UAV) network serves as the core infrastructure of the future low-altitude intelligent network, providing flexible aerial smart services for various industries through inter-UAV collaboration and ground-air connectivity. With the advancement of quantum computing, quantum algorithms pose a serious threat to UAV communication networks. Traditional authentication protocols based on classical number-theoretic problems are no longer secure against quantum attacks. To address the challenges of quantum threats and the inherent characteristics of UAVs, such as high mobility and resource constraints, this paper proposes a quantum resistant authentication and key agreement protocol for UAV networks. The comprehensive informal security analysis demonstrates the robustness of the protocol against various attacks, particularly attacks based on quantum computing. Furthermore, the authentication component of the protocol adopts a lightweight design, reducing computational overhead by up to 53.57%, thereby balancing security and efficiency.

A Quantum-Resistant Identity Authentication and Key Agreement Scheme for UAV Networks Based on Kyber Algorithm

Tao Xia, Menglin Wang, Jun He +3 more

Unmanned aerial vehicles (UAVs) play a critical role in various fields, including logistics, agriculture, and rescue operations. Effective identity authentication and key agreement schemes are vital for UAV networks to combat threats. Current schemes often employ algorithms like elliptic curve cryptography (ECC) and Rivest–Shamir–Adleman (RSA), which are vulnerable to quantum attacks. To address this issue, we propose LIGKYX, a novel scheme combining the quantum-resistant Kyber algorithm with the hash-based message authentication code (HMAC) for enhanced security and efficiency. This scheme enables the mutual authentication between UAVs and ground stations and supports secure session key establishment protocols. Additionally, it facilitates robust authentication and key agreement among UAVs through control stations, addressing the critical challenge of quantum-resistant security in UAV networks. The proposed LIGKYX scheme operates based on the Kyber algorithm and elliptic curve Diffie–Hellman (ECDH) key exchange protocol, employing the HMAC and pre-computation techniques. Furthermore, a formal verification tool validated the security of LIGKYX under the Dolev–Yao threat model. Comparative analyses on security properties, communication overhead, and computational overhead indicate that LIGKYX not only matches or exceeds existing schemes but also uniquely counters quantum attacks effectively, ensuring the security of UAV communication networks with a lower time overhead for authentication and communication.
