Quantum cryptography, grounded in principles of quantum mechanics such as superposition and quantum entanglement, represents a significant advancement in enhancing communications security. Methods like Quantum Key Distribution (QKD) offer encryption that is theoretically unbreakable, providing robust protection against cyber threats. However, the advent of quantum computing introduces challenges for conventional cryptographic algorithms, such as RSA and demands the development of new encryption strategies, including post-quantum methods. Integrating quantum encryption into the Internet of Things (IoT) promises to significantly enhance security levels. However, it is crucial to adapt these methods to the limitations of devices with restricted resources. As quantum computing advances, its role in data and communication protection will be crucial, though implementing these systems will face challenges related to cost and complexity. In the realm of industrial communications, selecting the appropriate protocol is essential for the efficient integration and operation of automated systems. Common industrial protocols, such as AMQP, CoAP, DDS, HTTP, MQTT, OPC, and XMPP, exhibit significant variations in aspects such as communication types, security, latency, resource usage, and reliability. Each protocol presents specific challenges, including security vulnerabilities and issues related to latency or resource usage, affecting its suitability for real-time and critical applications.

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.
