Mobile adhoc networks (MANETs) are characterized by their dynamic and decentralized nature, making them inherently vulnerable to security threats. This paper proposes a novel security framework that integrates Quantum Key Distribution (QKD) with error correction, privacy amplification, and distributed key management to enhance the security of MANETs. The experimental analysis was conducted using simulations to evaluate the effectiveness of the proposed framework across various node densities and mobility patterns. Our results demonstrate improved security in key exchanges but also highlight trade-offs in network performance metrics such as throughput and latency.

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.
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.
The rapid advancement of quantum computing poses a significant threat to conventional public-key cryptographic mechanisms deployed in Mobile Ad Hoc Networks (MANETs). Due to their decentralized architecture, dynamic topology, and resource-constrained nodes, MANETs require security solutions that are not only quantum-resistant but also computationally efficient. This paper presents a comparative evaluation of lattice-based and code-based post-quantum digital signature schemes for secure data transmission in MANET environments. The study focuses on analyzing key performance parameters including key generation time, signature and verification latency, end-to-end transmission delay, and overall security strength under varying mobility conditions. Simulation experiments are conducted using realistic mobility datasets and network models to assess the feasibility of deploying post-quantum signatures in dynamic MANET scenarios. The results demonstrate that while lattice-based schemes offer better computational efficiency, code-based schemes provide stronger security guarantees at the cost of increased communication overhead. This work highlights the critical trade-offs between security, performance, and scalability, and provides practical insights for designing lightweight post-quantum security frameworks for future mobile networks.
Background /Objectives: To improve the security in Mobile Ad Hoc network (MANET) by means of a Self Organized Quantum Key Authentication (SO-QKA). Methods/Statistical Analysis: The key objective of SO-QKA technique is to improve data security and mobile node authentication in MANET. Initially, SO-QKA technique generates quantum key for mobile node data transmission along the route path in MANET. Next, SO-QKA technique formulates self organized key for every mobile node with its quantum key for corresponding data transmission at specific instances. With the help of generated self organized key, SO-QKA technique finds secure route for transmitting the data in MANET. Finally, SOQKA technique is performs key matching at the destination node where the verification of the mobile node is checked with the mobile node id of self organized key and data authentication is verified with quantum key and destination id. Findings: Experimental evaluation of SO-QKA technique is done with the performance metrics such as data loss rate, data transmission rate, security, execution time. Experimental analysis shows that the SO-QKA technique is able to improve the security and also improves the data transmission rate comparable to the state-of-the-art works. Applications/ Improvements: It can be further enlarged with implementation of new algorithm model with different parameters which improves high authentication and confidentiality Keywords: Data Communication, Key Matching, Mobile Ad Hoc Network, Mobile Node, Quantum Key, Self Organized Key
The proliferation of mobile networks and their increasing importance to modern life, combined with the emerging threat of quantum computing, present new challenges and opportunities for cyber-security. This paper addresses the complexity of protecting these critical infrastructures against future quantum attacks while considering operational sustainability. We begin with an overview of the current landscape, identify the main vulnerabilities in mobile networks, and evaluate existing security solutions with new post-quantum cryptography (PQC) methods. We then present a quantum-secure architecture with PQC and Quantum Key Distribution (QKD) tailored explicitly for sustainable mobile networks and illustrate its applicability with several use cases that emphasize the need for advanced protection measures in this new era. In addition, a comprehensive analysis of PQC algorithm families is presented, focusing on their suitability for integration in mobile environments, with particular attention to the trade-offs between energy consumption and security improvements. Finally, recommendations for strengthening mobile networks against quantum threats are provided through a detailed examination of current challenges and opportunities.
As evolving digital ecosystems become increasingly interconnected and reliant on digital transactions, secure, private and user-centric identity solutions are garnering more spotlight than ever before. In this paper, we propose an innovative architecture that integrates quantum key distribution (QKD) with blockchain-based self-sovereign identity (SSI) systems for secure key distribution and network/user management for mobile networks with advanced 6G network capabilities. The proposed approach leverages the advanced security guarantes of QKD to ensure the confidentiality and integrity of communications and uses the decentralized and immutable nature of blockchain technology to give individuals/organizations control over their digital identities in mobile environments. We then go on to expound on the foundations of architectural components and discuss its implications for various telecom specific services and applications. Finally, we present challenges and future directions to provide quantum communication support against future digital threats and a decentralized framework for identity management with the global pursuit of more privacy-friendly and usercentric digital services, and offer comparisons with traditional approaches.
