The explosive growth of Industrial Internet of Things (IIoT) technologies has been reshaping manufacturing, energy, transportation and infrastructure with real-time monitoring and automation supported by predictive analytics. The more interconnected machines are, the more vulnerable they become to advanced cyberattacks. RSA and ECC are two of the dominant cryptographic algorithms that 60% of the IIoT communications today. They are still susceptible to quantum computing attacks, especially from Shor, which can easily break public-key encryption. This new risk, and the threat it represents, calls for a monitoring of the quantum situation by adding Post Quantum Cryptography (PQC) to guarantee data privacy and resilient systems. This work studies the quantum-empowered security approach to IIoT environment and considers lattice-based, hash-based and code-based cryptography techniques immune to quantum attacks. This paper investigates the industrial system design demands, identifies some of these weaknesses, and presents a secure communication architecture including post-quantum cryptography for device authentication, secure firmware updates and data encryption. Studies show that due to constraints in resources, triage for IIoT devices is difficult, especially because of limitations of processors, among others; latency and scalability are two issues. The approach proposed showcases a means for industrial cybersecurity to benefit from post-quantum cryptography without losing efficiency.
Industrial Internet-of-Things (IIoT for short) which is the basis of Industry 4.0, extends Internet connectivity beyond traditional computing devices, for example, smartphones, computers, laptops, webcams, etc., to the physical world for improving accuracy and efficiency while reducing the production cost. However, there exists large numbers of security threats, such as data leakage and privacy threats. To solve these issues, we first present a system model, security requirements and then proposed a post quantum secure multi-party collaborative signature with deterability in the IIoT environment. In this scheme, formal security proofs are given in the random oracle assuming that AMLWE and AMSIS problem are hard. We also demonstrate the potential utility of our proposed scheme by evaluating its performance.
The Internet of Things (IoT) is involved in almost every industry, paving the way for innovative applications, including smart cities, intelligent systems, smart homes, smart agriculture, healthcare, and more. However, due to their asset value, these applications are under continuous and evolving cyberattacks. Furthermore, the advent of quantum computing presents a severe threat to traditional cryptographic methods that typically secure IoT systems, potentially rendering existing security mechanisms ineffective against quantum-enabled attacks. To tackle quantum-enabled and traditional cyberattacks, post-quantum cryptography (PQC) has emerged as a promising solution for providing future-proof security for IoT devices and networks against the quantum computing threat. PQC algorithms can resist cyberattacks from classical and quantum computers, ensuring long-term security solutions. This article explores the integration of PQC into practical IoT systems. It highlights the vulnerabilities of classical cryptographic methods and the necessity of transitioning to quantum-resistant solutions. Moreover, the implementation of PQC on IoT systems is analyzed. By proactively exploring the opportunities and challenges associated with PQC, this research lays out future directions for implementing robust, scalable, and secure IoT systems.
The Internet of Things (IoT) has grown rapidly, transforming various aspects of daily life into intelligent systems capable of collecting and exchanging data in real time. At the same time, advances in quantum computing have given rise to powerful quantum computers capable of processing complex tasks at unprecedented speed. This disparity between the limited resources of IoT devices and the capabilities of quantum computers poses significant security challenges. Quantum computers introduce new vulnerabilities that threaten IoT systems, particularly in critical applications such as connected healthcare, industrial networks, smart infrastructure, and secure embedded systems. This study reviews the existing literature on post-quantum cryptography (PQC) applied to IoT devices. It analyzes the characteristics and security requirements of IoT environments, current security technologies, and unresolved issues. It highlights the growing threat of post-quantum attacks and the need to adapt security strategies. Finally, the study explores post-quantum code-based cryptosystems as solutions to enhance the security of resource-constrained IoT applications and ensure their resilience against future challenges.
The rapid convergence of sixth-generation (6G) networks and the Internet of Things (IoT) offers enormous potential for ultra-reliable, low-latency, and massive device connectivity. However, this integration also raises security and privacy concerns, particularly in light of new threats from quantum computing that could undermine traditional cryptography. The architecture of quantum-safe IoT networks that can withstand post-quantum security threats is thoroughly discussed in this review. It addresses the challenges related to how to use blockchain technology to provide decentralized trust as well as secure transactions, how to use post-quantum cryptographic algorithms to protect data confidentiality, and the best way to use a trust management architecture to improve identity verification, authorization, and authentication in the diverse IoT environment. The paper then examines scalability considerations, resource constraints, and interoperability problems that impact safe IoT deployments in the 6G era. This work serves as a roadmap for researchers and practitioners who aim to create robust and future IoT infrastructure and then maintain their security in a post-quantum world by integrating recent research patterns, solution development, and considerations related to real-world implementation.
The prospect of large-scale quantum computers necessitates the design, development, and standardization of post-quantum cryptography (PQC). Industrial control systems (ICS) and critical infrastructures are expected to be among the first industrial environments to adopt PQC. As their components have a long life span (≥ 10 years) and are increasingly interconnected to form an Industrial Internet of Things (IIoT), they require strong and long-lasting security guarantees. Because of these high-security requirements, IIoT products are also increasingly equipped with additional hardware security elements — often Trusted Platform Modules (TPMs).
