Quantum computing is expected to mature in the coming years; however, traditional secure schemes, which might be used for computations and communications on unmanned aerial vehicles (UAVs), will need better solutions than simply updating passwords while disregarding specific systems like navigation or collision avoidance. In this paper, we propose an original method for improving the security of UAVs by embedding quantum-resistant cryptographic algorithms. Secure communication using lattice-based cryptography (Kyber) and message authentication using hash-based signatures (SPHINCS+) were selected based on the UAV hardware hierarchy for which these post-quantum systems are optimized. The developed system was tested in different flight conditions, including high-density UAV swarms, with the help of a simulation environment. The results show that secure communication between quantum-safe navigation and collision avoidance modules is possible with low latency, which does not cause a significant increase in computational cost or battery life consumption.

This study presents "Quantum Lattice," an innovative theoretical framework designed to ensure the security of Unmanned Aerial Vehicle (UAV) swarm communications in the era after quantum computing. Given the risk posed by quantum computing to conventional cryptography techniques, it is imperative to develop security solutions that are immune to quantum attacks specifically designed for UAV systems. Utilizing sophisticated lattice-based encryption, we employ the Short Integer Solution (SIS) problem and a novel Aerial Lattice Traversal (ALT) algorithm to provide strong security while preserving real-time performance essential for UAV operations. Simulations performed on a testbed which incorporates quantum technology show substantial enhancements compared to conventional approaches. These benefits include a 42% decrease in latency, a 28% increase in throughput, a 63% reduction in packet loss, and a 37% decrease in energy consumption, especially in dense swarm setups with up to 1000 nodes. The mathematical principles that underlie our approach, including δ--ary lattices and their cryptographic applications, are thoroughly discussed. In addition, the study investigates the incorporation of our framework with developing technologies like neuromorphic computing and AI-powered adaptive security mechanisms. In the quantum computing era, our results provide a foundation for secure, scalable, and robust UAV swarm operations, effectively tackling significant issues in both civilian and military contexts.
Unmanned Aerial Vehicles (UAVs), commonly known as drones, are increasingly being employed across a broad spectrum of applications, ranging from military operations to commercial purposes. However, as UAVs become more integrated into everyday life, security and privacy concerns are similarly escalating due to vulnerabilities arising from operating on open wireless channels and having limited onboard computational resources. Moreover, with the emergence of quantum computers, conventional cryptographic methods that ensure the security and privacy of UAV communications are at severe risk. These risks encompass the possibility of unauthorized access, breaches of data, and cyber-physical attacks that jeopardize the integrity, confidentiality, and availability of UAV operations. Quantum computers are expected to break the conventional cryptography methods, such as symmetric and asymmetric schemes, with the support of Grover’s and Shor’s algorithms, respectively. Consequently, traditional cryptographic algorithms must give way to quantum-resistant algorithms, referred to as Post-Quantum Cryptography (PQC) algorithms. Although researchers actively develop, test, and standardize new PQC algorithms, the threat persists despite the progress made through these consistent efforts. This review article first examines the security and privacy landscape, including threats and requirements of UAVs. This article also discusses PQC and various PQC families and the status of the NIST’s implementation and standardization process. Lastly, we explore challenges and future directions in implementing PQC for UAVs.
The seamless integration of Unmanned Aerial Systems (UAS) into public airspace necessitates a robust UAV Traffic Management (UTM) system. Information security in communications plays a pivotal role in ensuring the operational safety of the UTM. Maintaining the integrity and authentication of unicast communications, such as command and video information, is imperative to thwart tampering and impersonation. Encryption emerges as an optimal solution for safeguarding such data. Efficient utilization of symmetrical encryption mandates the imple-mentation of secure key exchange mechanisms. However, intro-ducingAuthenticated Key Exchange (AKE) standards on diminutive Unmanned Aerial Vehicles (UAVs) encounters problems due to hardware limitations. To surmount this challenge, lightweight cryptographic algorithms tailored for resource-constrained hard-ware have been developed. Nonetheless, both lightweight and conventional cryptographic algorithms are susceptible to quantum computing threats. In response, post-quantum cryptographic primitives are undergoing standardization. This study assesses post-quantumKey Encapsulation Mechanism (KEM) candidates, namely CRYSTALS-Kyber, Hamming Quasi-Cyclic (HQC), and BIKE, on hardware resembling small UAVs. The evaluation of these algorithms focuses on computation time, considering real-time tasks during flights. The findings affirm the viability of employing unmodified standards on resource-constrained hardware concurrently with other priority tasks. Furthermore, quantum-vulnerable standards are also investigated to compare their performance against their more secure counterparts. All three post-quantum KEM candidates demonstrate usability in this environment, with CRYSTALS-Kyber being recommended for its superior performance, even surpassing certain prevailing standards.
With the widespread deployment of unmanned aerial vehicles (UAVs) in both military and civilian domains, the demand for secure and encrypted communications in UAV networks integrated with ground stations has become increasingly prominent. Authentication and key agreement protocols are widely regarded as essential technical mechanisms for ensuring the security of data transmission in wireless communication environments. However, the rapid advancement of quantum computing technologies poses potential security threats to conventional protocols based on elliptic curve cryptography. To address these challenges, this paper proposes a quantum-secure authentication and key agreement protocol tailored for UAV–ground station communication scenarios. By incorporating Crystal-Kyber, the proposed protocol ensures quantum resistance while striving to minimize system computational overhead. The results of the informal security analysis indicate that the proposed protocol can effectively withstand a variety of known attacks. In addition, comprehensive comparative evaluations with existing related protocols demonstrate that, while maintaining low computational overhead, the proposed scheme exhibits stronger robustness in terms of security and functional properties.
The first comprehensive framework for deploying NIST-standardized post-quantum cryptography in military UAV systems, bridging the critical gap between theoretical PQC algorithms and practical implementation on resource-constrained drone platforms. We provide rigorous mathematical security proofs for lattice-based schemes (Kyber, Dilithium, Falcon, SPHINCS+) tailored to MAVLink protocol requirements, extensive performance benchmarking demonstrating <1% operational overhead on embedded military hardware, and four complete implementation architectures with working code. Our NATO-compliant security frameworks integrate STANAG requirements with PQC mandates—addressing a gap in existing civilian-focused literature. We validate our approach through an MQ-9 Reaper retrofit case study achieving zero mission degradation, providing the defense community with an actionable roadmap for transitioning military UAV fleets to quantum resistance before cryptographically-relevant quantum computers emerge (projected 2028-2033).
