A Survey on Post-Quantum Cryptography for 5G/6G Communications

Rongjie Zhou, Huaqun Guo, Francis E C Teo +1 more

As quantum computing capabilities accelerate, together with the discovery of Shor's Algorithm, existing encryption protocols, such as TLS (Transport Layer Security) and IPsec (Internet Protocol Security), face the risk of becoming obsolete. This vulnerability poses a significant challenge for 5G and 6G mobile networks, which rely on these protocols for data transmission. This survey explores the potential of Post-Quantum Cryptography (PQC) algorithms as viable alternatives for securing mobile communications. Through a comprehensive review of NIST-shortlisted PQC algorithms, this paper examines their relevance, efficiency, and adaptability in 5G and 6G architectures. Case studies, including real-world implementations by Amazon Web Services (AWS) and IBM, illustrate the growing acceptance and practical applicability of these quantum-resistant algorithms.

A Contemporary Study on Quantum-Computing Security Mechanisms in 5G Networks

Et. al. Rydhm Beri

5G communication technology works with the integration of several technologies viz. Cloud Computing, network partitioning and software based networks. This integration allows the communication between thousands of device across the world which have enormous issues related to data protection, data authenticity, and data confidentiality. So, there is an immense need of secure protocols to face or resolve security related issues related to design and operation of 5G network. Moreover, some structured cryptography protocols required to develop and accomplish data security in 5G communication. The study focussing on the comprehensive consequences of quantum computing on security implementations of 5G mobile communications. The study discussing about the cryptographic algorithm used in 5G, and what are the various consequences of involvement of quantum computing.

Mitigating 5G security challenges for next-gen industry using quantum computing

Cherry Mangla, Shalli Rani, Nawab Muhammad Faseeh Qureshi +1 more

5G has been launched in a few countries of the world, so now all focus shifted towards the development of future 6G networks. 5G has connected all aspects of society. Ubiquitous connectivity has opened the doors for more data sharing. Although 5G is providing low latency, higher data rates, and high-speed yet there are some security-related vulnerabilities. Those security issues need to be mitigated for securing 6G networks from existing challenges. Classical cryptography will not remain enough for securing the 6G network. As all classical cryptography can be disabled with the help of quantum mechanics. Therefore, in the place of traditional security solutions, in this article, we have reviewed all the existing quantum solutions of 5G existing security issues to mitigate them and secure 6G in a Future Quantum World.
