ABSTRACT Unmanned aerial‐vehicle (UAV) networks have been ubiquitous and play an inevitable role in internet‐of‐drones. Their reliance on mesh networking and the MAVLink protocol makes them highly vulnerable to severe and potentially lethal cyberattacks. The classical public‐key encryption/decryption scheme employing integer‐factorization and primitive‐root‐type problems (such as the RSA system) has been commonly used for many years; however, its security is compromised by future advancements in quantum computing (through Shor's algorithm). In this work, we present a quantum‐secure authentication protocol for UAV‐based IoD applications, emphasizing user anonymity. A security analysis is presented which guarantees correctness, privacy, and robustness against numerous active and passive attacks in both the classical and quantum settings. Moreover, a real‐time testbed experiment of running time on Raspberry Pi 5 boards to evaluate the computational overhead of different cryptographic primitives illustrates its practicality. Finally, a performance comparison of filtering accuracy and resistance to unknown attacks with related existing schemes demonstrates its scalability and usefulness in real‐world applications.
Remotely-Controlled Aerial Vehicles (RCAV), popularly known as drones, have gained wide popularity in several applications from military to civilian due to the usage of sensors, actuators, and processors with wireless connectivity for data collection and processing. However, data security and authentication are still challenging as sensitive data is collected and shared in RCAV using an open channel, i.e., the Internet. The existing security of Internet-of-Drones (IoD) communication mainly depends on the hardness of discrete logarithms and factorization problems. However, due to Shor's algorithm, both authorized and secure transmissions are challenging in the presence of highly scalable quantum computers. To mitigate the aforementioned issues and challenges, in this article, we propose an authorized and secure communication scheme for IoD based on Ring Learning With Error (RLWE) problem on lattices, which have the potential to sustain low computation and quantum attacks. The proposed scheme supports mutual authentication and has an efficient session establishment. The evaluation results show that the proposed scheme has superior performance as compared to the existing state-of-the-art solutions on benchmark data sets using various evaluation metrics.
The rapid advance of manufacturing Unmanned Aerial Vehicles (UAVs, aka drones) has led to a rise in the use of their civilian and commercial applications. The access of these drones to controlled airspace can be efficiently coordinated through particular layered network architecture, often referred to as the Internet-of-Drones (IoD). The nature of IoD, which is deployed in an open-access environment, brings significant safety and security concerns. Classical cryptosystems such as elliptic curve cryptography, Rivest-Shamir-Adleman, and Diffie-Hellman are essential building blocks to secure communication in the IoD. However, with the rapid development of quantum computing, it will be easy to break public-key cryptosystems using efficient quantum algorithms like Shor’s algorithm. Thus, building quantum-safe solutions to enhance IoD security has become imperative. Fortunately, quantum technologies can provide unconditional security solutions to protect data and communications in the IoD environment. This paper proposes a quantum-based scheme to prevent unauthorized drones from accessing a specific flight zone and authenticates the identities and shared secret messages of involved entities. To do so, we used a quantum channel to encode the private information based on a pre-shared key and a random key generated in session. The involved entities also perform mutual authentication and share a secret key. We also provide the security proofs and analysis of the proposed scheme that indicates its resistance to well-known attacks.
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.
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.
The use of drones in military operations is a growing phenomenon that presents substantial security implications, especially related to authentication, data integrity, and the treatment of cyber threats. While traditional schemes like Elliptic Curve Cryptography (ECC) have computational efficiency, they are susceptible to quantum attacks. To solve the aforementioned problem, in this paper, we design a Lightweight and Quantum Resistant Authentication Protocol for Military IoD Using Dilithium Signatures, which is a post-quantum cryptographic (PQC) method implemented using the PQC solution based on lattice-based cryptographic evidence. The proposed protocol provides quantum-safe mutual authentication of drones, soldiers, and the command center (CC) while also protecting against impersonation attacks and side-channel attacks. In contrast to ECC-based authentication and its vulnerability to Shor’s Algorithm, the proposed system is long-term quantum secure. While Dilithium incurs increased computational and communication costs, our performance evaluations show that it provides security against quantum adversaries and replay attacks, thereby deeming it a worthwhile choice, especially in light of the swift advancements in ASIC technology. In an effort to be truly efficient, signature compression, parallel authentication verification, and an improved key management approach further enhance the scalability of the proposed scheme in the military Internet of Drones (IoD) network. The results substantiate the necessity of deploying full post-quantum authentication schemes to protect UAV networks. We intend to focus on developing energy-saving hardware and optimizations for real-world deployment in future work.
