Unencrypted communications between unmanned aerial vehicles (UAVs) are susceptible to various security attacks, such as interception and spoofing. Both symmetric and asymmetric cryptography currently allow for secure communication between parties. However, industry and academia are working on implementing quantum computers, which will invalidate several of the most widely used cryptographic algorithms. As researchers develop novel quantum encryption methods, they will need standardized testing approaches to determine which are most optimal, especially for the unique characteristics of UAV systems. This paper describes a methodology to test and measure the efficiency of key exchange algorithms for a UAV communicating with a ground control station (GCS). The method requires a framework that models a UAV performing tasks while communicating in encrypted messages with the GCS. In addition, the calculations used for comparing algorithms require a purpose-built bandwidth equation for the quantum algorithm. The first test of this methodology is an experiment designed to compare classical key exchange with the 256-bit Advanced Encryption Standard (AES-256) and quantum key distribution (QKD) used with a variety of parameters in the framework. A comparison of the runtime of each model facilitates the evaluation of each key exchange algorithm for UAV systems. This methodology can be used to test the efficiency of other post-quantum cryptographic algorithms in the future.

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.
Unmanned Aerial Vehicles (UAVs) have gone from single platforms that were remotely piloted to fully networked, autonomous cyber-physical systems that operate in the civilian, industrial and defense arenas. Their increasing reliance on wireless communication for command and control, cooperative sensing, distributed decision-making and swarm coordination has raised the level of communication security to the point where it has become a mission-critical requirement. Contemporary UAV security architectures are much based on classical public-key–based cryptography (RSA and elliptic are the most well-known) whose security assumptions become fundamentally vulnerable against the presence of large-scale quantum computing. This chapter gives a comprehensive and future-oriented discussion about post-quantum cryptography (PQC)-based security models for UAVs communication and information exchange networks. Quantum resistance should be applied not only at the algorithmic level but across the whole UAV communications trust stack, which is the main argument. Part I set the conceptual and technical ground by affecting a short range of the improvement of UAV communication systems, in articulating a system quantum-era threat model and giving a motivation for mission-adaptive, cross-layer security architectures. The discussion makes the long-term confidentiality, survivability of the system and continuing operation more robust, and the security of UAV with PQC enabled is no longer speculative, but is considered a strategic requirement.

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.
