“…In light of these concerns, the integration of quantumbased technologies, particularly Quantum Communication (QC) and Quantum Cryptography (QCrypt), is presented as a promising avenue for addressing these security challenges (Wang et al, 2020). QC offers unconditional security, as eavesdropping attempts are detectable, making it a valuable asset in safeguarding data transmission (Ngobeni et al, 2020;Djordjevic, 2022). However, as quantum-assisted crypto analysers pose a new threat, the security community must focus on devising post-quantum techniques and standardized security protocols (Suomalainen et al, 2018).…”

“…Additionally, outlines that a significant portion of IoT applications are expected to run on NB-IoT deployment mode by the end of 2025. However, enhanced usecases introduce security challenges that traditional cryptographic solutions cannot effectively address due to stringent latency requirements (Djordjevic, 2022;Dutta, 2022). The abuse of telecommunications infrastructure by surveillance spyware further exacerbates the challenges faced by IRN signalling traffic (Holtrup et al, 2021).…”

Signalling security is critical for next-generation mobile (NGN) networks to ensure integrity, privacy, and confidentiality of communication protocols. However, recent research on existing 5G standards has uncovered vulnerabilities that could be exploited by emerging surveillance threats such as HiddenArt and Harvest Now Decrypt Later (HNDTL), as well as the prospect of quantum computing threatening to break classical cryptographic techniques. This systematic literature review (SLR) investigates quantum-based signalling solutions to mitigate these threats in interconnect and roaming 5G networks (IRN) over IP eXchange for Narrowband Internet of Things (NB-IoT) traffic. A database search was conducted, studies were selected and compared based on methods, approaches, techniques, and limitations. The SLR found that quantum key distribution (QKD) combined with quantum teleportation (QT) can protect and mitigate threats and attacks on signalling networks when protocols interact and interoperate in carrier networks. QKD techniques can be used for L1 protocols, while secure direct quantum communication can be used for L2 protocols. This study concludes that further studies are needed to integrate different techniques and protocols for L1/L2 signalling networks to create a robust quantum-secure signalling model for global interconnect and roaming NGN.

The internet of things (IoT) has been used in a wide range of applications since its emergence, including smart cities, intelligent systems, smart homes, smart agriculture, and healthcare. IoT systems rely on information processing and sharing, where data leakages may jeopardize their security and privacy. On the other hand, quantum computers are poised to solve complex problems that traditional computers cannot. However, due to the fact that the majority of cyber algorithms are based on significant computational complexity, quantum computing poses a substantial threat to the cyber security of global digital infrastructure, including IoT networks, smart cities, banking, and intelligent infrastructure. This chapter discusses potential security and privacy measures for a post-quantum world against threats posed by quantum computing, including post-quantum cryptography, quantum software testing, post-quantum blockchain technology, and architectural considerations for creating post-quantum secure IoT systems.
