| Abstract | 5th Generation(5G) -enabled Internet of Things (IoT) connects billions of devices for high-speed data transfer. The data collected fuel many automation applications such as smart cities, industrial automation 5.0, autonomous vehicles and healthcare sectors. However, the critical challenges concerning such an environment are Open Web Security and Mutual Authentication. The recent security protocols of IoT are based on hard mathematical cryptographic structures. Nevertheless, dependency on the security of classical cryptographic primitives is at risk of being broken by Quantum Computing. Recent Quantum attacks on IoT security have motivated us to survey Quantum-resistant solutions comprehensively. Therefore in this paper, we analysed how the technology shifts from classical cryptographic techniques towards quantum-enabled solutions to achieve end-to-end security. The main objective of this survey is to provide a systematic roadmap in the area of Quantum secured 5G-enabled IoT communication by covering current research on 5G-enabled IoT with its key enabling technologies, threats imposed on 5G-enabled IoT applications, state-of-the-art quantum-based solutions and initiatives. A detailed overview of the quantum computing preliminaries, Post Quantum Cryptography (PQC) schemes, Quantum Cryptography (QC), and Quantum Key Distribution (QKD) with their significant advantage in securing IoT-enabled communication over classical scenarios are also presented. Particularly, we emphasize Post-Quantum resistant techniques that must be used soon to secure 5G-enabled IoT communications. The comparative analysis of quantum-resistant schemes with classical cryptographic schemes in terms of key size, data size, time complexity and impact of quantum computers on these schemes are discussed. This paper identifies the technical challenges in Quantum-based schemes and provides future research directions to enable Post-Quantum resistant cryptography for secure communication in 5G-enabled IoT. © 2023 Elsevier B.V. |
