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.

Enhancement of a Quantum-Resistant Identity Authentication and Key Agreement Scheme for UAV Networks

Hameurlaine Hicham, Mustapha Benssalah, Noureddine Mehallegue +1 more

Secure communication in unmanned aerial vehicle (UAV) networks is critical for a wide range of civil and military applications, from precision agriculture and disaster response to critical infrastructure monitoring. These missions require lightweight, tamper-resistant, and quantum-secure authentication mechanisms. We examine the recently proposed Quantum-Resistant Identity Authentication and Key Agreement Scheme for UAV Networks Based on the Kyber Algorithm (LIGKYX) and demonstrate its critical weaknesses, including a lack of Perfect Forward/Backward Secrecy (PFS/PBS), and desynchronization vulnerabilities. To address these limitations, we propose a novel authentication and key agreement protocol that integrates SRAM-based Physical Unclonable Functions (PUFs) with the Kyber post-quantum key encapsulation mechanism, eliminating the reliance on Elliptic Curve Cryptography (ECC) and stateful counters used in LIGKYX. The security of the proposed protocol is validated through both formal and informal analyses, demonstrating strong resistance to replay, impersonation, man-in-the-middle, desynchronization, and UAV capture attacks. Performance evaluation confirms its efficiency: the total communication overhead is reduced by 7.1% (from 1836 bytes in LIGKYX to 1705 bytes in the proposed scheme), and the total authentication time is reduced by more than 54%, from 87.84 ms in LIGKYX to 40.23 ms in the proposed scheme. These improvements demonstrate that the protocol not only strengthens security but also significantly reduces computation and communication costs. Overall, the proposed solution offers a lightweight, scalable, and quantum-resistant authentication framework tailored for resource-constrained UAV environments, representing a substantial advancement over existing schemes such as LIGKYX.

APQE-CDA: A PUF-Based Post-Quantum End-to-End Cross-Domain Authenticated Key Agreement Protocol for IOD System

Xinxin Liu, Huanwei Wang, Wei Liu +2 more

To address the issues of high computational overhead, vulnerability to physical capture attacks, and insufficient in offering quantum resistance in traditional blockchain-based cross-domain authentication protocols for collaborative unmanned aerial vehicles (UAVs) missions, we propose APQE-CDA, a PUF-based post-quantum end-to-end cross-domain authentication protocol. The proposed protocol employs a lightweight bucket shifter PUF (BS-PUF) to reduce the computational overhead of UAVs while providing resilience against physical capture attacks. Static Random-Access Memory (SRAM) PUF-enhanced Kyber post-quantum cryptography is utilized to ensure secure quantum resistance. In APQE-CDA, we exploit the reversibility of BS-PUF to facilitate secure Challenge Response Pair (CRP) storage on the blockchain while achieving lightweight identity authentication through commutativity. We integrate SRAM PUF randomness into the Kyber key generation mechanism to eliminate key storage on UAVs while ensuring quantum-resistant security in the authentication interactions. Finally, Burrows Abadi Needham (BAN) logic, Real-or-Random (ROR), and informal security analysis are adopted to demonstrate the security of the proposed scheme. Experiments conducted on the Raspberry Pi 5 and FPGA platforms show superior computational efficiency, lower power consumption, and enhanced quantum-resistant security compared to existing solutions. Furthermore, extensive validation through the NS3 network simulator and Hyperledger Fabric framework substantiates the protocol’s authentication efficiency and practical viability in real environment conditions.
