Abstract
The rapid development of quantum computing poses a significant threat to the security of current cryptographic systems, including those used in User Equipment (UE) for mobile communications. Conventional cryptographic algorithms such as Rivest–Shamir–Adleman (RSA) and Elliptic curve cryptography (ECC) are vulnerable to quantum computing attacks, which could jeopardize the confidentiality, integrity, and availability of sensitive data transmitted by UEs. This demo paper proposes the integration of Post-Quantum Cryptography (PQC) in TLS for UE Communication to mitigate the risks of quantum attacks. We present our setup and explain each of the components used. We also provide the entire workflow of the demo for other researchers to replicate the same setup. By addressing the implementation of PQC within a 5G network to secure UE-to-UE communication, this research aims to pave the way for developing quantum-resistant mobile devices and securing the future of wireless communications.
