A Secure Quantum Protocol for Vehicular Ad Hoc Networks

Koushik Challagundla, Kartick Sutradhar

Vehicular ad hoc networks (VANETs) connect numerous vehicles, allowing efficient vehicle-to-vehicle communication through a dedicated network. The dynamic connectivity of VANETs facilitates spontaneous communication among diverse vehicles, enabling real-time exchange of crucial information like traffic conditions, road hazards, and other pertinent data. This collaborative network enhances road safety and traffic efficiency by enabling vehicles to share information and adapt to changing conditions in their proximity, ultimately improving the overall transportation system. This paper proposes an authentication protocol designed to be unconditionally secure against quantum attacks. The research delves into integrating quantum authentication with blockchain technology to establish a secure framework for VANETs. We introduce a quantum blockchain framework focused on bolstering the security of VANETs. The paper provides a thorough analysis of the potential of quantum blockchain in addressing common security threats in VANETs, including data tampering, eavesdropping, and unauthorized access.

Quantum based Cryptography for Secured Data Communication in Mobile Ad-Hoc Network

S. Sangeetha, S. Sathappan

A Mobile Ad-Hoc Network (MANET) is an infrastructure-less network of mobile devices that are linked without any wire. Every mobile device in MANET moves in any direction. Security is a key problem in MANET of providing the secured communication with routing and packet forwarding process. In order to improve the security during the data communication, Quantum Key Distribution based Secured Data Communication (QKD-SDC) technique is designed in MANET. In QKD-SDC technique, quantum based cryptography used the quantum mechanics for secured data communication. Initially, Quantum based Cryptography performs Quantum Key Generation and Quantum Key distribution process. In Quantum Key Generation process, quantum key is generated and the key is shared to the receiver. With help of the quantum key, the original data gets encrypted as qubits. In Quantum Key distribution process, the qubits are sent to the receiver end through quantum communication channel along with the quantum key. At the receiver end, when the quantum key gets matched with receiver's quantum key, the qubits are decrypted to obtain the original data. When the key is not matched, the qubits get dropped. This in turn helps to improve the secured data communication in quantum communication channel. Experimental evaluation of QKD-SDC technique is carried out with the performance metrics such as data loss rate, throughput and time for secured data delivery. Experimental analysis shows that the QKD-SDC technique is able to reduce the data loss rate and also improves the throughput when compared to the state-of-the-art works.

Survey on Post-Quantum Cryptographic Techniques for Securing MANETs

A. H. Galadima, Ahmed Abubakar Aliyu, F. U. Zambuk +4 more

Mobile Ad Hoc Networks (MANETs) enable flexible, infrastructure-less communication for mission critical applications but they are vulnerable impersonation and routing attacks. Quantum computing threatens classical public-key primitives (RSA, ECC) used in MANET security, driving interest in post-quantum cryptography (PQC) for decentralized, resource limited settings. This survey reviews PQC techniques and its application to MANETs, focusing on signature, key exchange, and encryption primitives from lattice based, code base, hash base, and multivariate based families. Synthesizing findings from 40+ studies, we compare security, overheads, and feasibility for constrained nodes and dynamic topologies. Lattice based schemes (Kyber, Dilithium) offer the best balance of security and efficiency, though large keys and CPU costs hinder adoption. Lightweight primitives and hybrid models (PQC with symmetric cryptography) show promise. Key gaps include few lightweight implementations, limited routing level integration (e.g., OLSRv2), and scarce real world validation. Future work should optimize PQC for low power devices, embed it into MANET protocols, and test via simulation and hardware to enable practical, quantum resilient deployments.
