Summary Internet of Everything (IoE) is one of the emerging technologies in the advancement of digital life and innovation. But the major issue that is to be addressed is the security concerns over such an environment, especially in end‐to‐end device communication. The proposed approach primarily focuses on reliable end‐to‐end device communication using post‐quantum location‐aware encryption, aiming to achieve confidentiality and integrity in an Internet of Everything environment.

Numerous traditional encryption algorithms are now in use, while post‐quantum encryption is being studied and considered as a quantum‐safe substitute. The proposed approach also demonstrates a robust attack model which focuses on communication network threats like namely, Man‐In‐The‐Middle and Sybil attacks intending to evaluate the overall performance of the network by analyzing the performance parameters like, number of nodes in the network, message size, execution time, and memory consumption by the nodes and aiming to achieve an appreciable accuracy in an IoE environment.

Joining people, processes, data, and gadgets in a sustainable way is called the environmentally friendly Internet of Everything (Green IoE). Traditional encryption techniques, however, face serious security threats from the advent of quantum computing. Discrete logarithmic and factorisation issues make current cryptography systems like RSA and ECC susceptible to quantum attacks. In order to improve Green IoE security without sacrificing energy efficiency, this article suggests using lightweight post-quantum signature methods. The promising members are the ones derived from the lattice, hash, or multivariate quadratic theory when it comes to the choice between security and performance. This research identifies how it is possible to integrate quantum-safe security for Green IoE applications without eradicating the low power requirements inherent in these systems. It is by combining these little post-quantum signatures into Green IoE that it becomes possible to come up with a safe system that meets the set environmental standards. Realizing the need to construct a dependable safety system with Green IoE in the post-quantum period, the research evaluates the strength and speed of the proposed cryptography algorithms.
The Internet of Things (IoT) has revolutionized the way devices communicate and interact, enabling seamless integration into various aspects of daily life by billions of connected devices equipped with small, embedded controllers that monitor and manage our increasingly interconnected world. The swift growth of IoT devices has led to significant concerns about data security and privacy. Traditional cryptographic algorithms, usually lightweight cryptography, are effective against classical computing threats. However, they are vulnerable to attacks from emerging quantum computing technologies, which can quickly solve the mathematically hard problems used in classical cryptography. Post-Quantum Cryptography (PQC) offers promising solution by providing cryptographic primitives resistant to quantum attacks. This chapter addresses challenges posed by resource constrained IoT devices, like limited processing power and memory. It also explores the integration of PQC algorithms suitable for IoT environments, considering factors like computational efficiency and resistance to quantum attacks.
The rapid proliferation of Internet of Things (IoT) devices has revolutionized digital communication, yet it simultaneously poses unprecedented security challenges due to constrained device capabilities and increasing cyber threats. Conventional cryptographic techniques, while currently effective, are vulnerable to emerging quantum computing technologies that threaten to render classical encryption obsolete.

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.

The given assessment explains a quantum-advanced scenario that is operationally feasible and serves as a platform for quantum key distribution (QKD) along with classical post-quantum algorithms to deliver end-to-end confidentiality, integrity, and authentication features to a wide range of IoT devices. The model, by the virtue of quantum entanglement and photon polarization used in the creation of tamper-evident communication links, is invulnerable to adversarial-aided eavesdropping and computational assault methods and further offers a hybrid encryption protocol that has been demonstrated to alleviate key generation and exchange latency trade-offs - simultaneously maintaining scalability and effectiveness in resource-constrained IoT node environments. The key compromise probability is significantly lowered in the experimental results, along with the keys' entropy levels, which were generated in the pure QKD space as opposed to classicalbased RSA and ECC methods. Also, the framework investigates lightweight quantum-safe authentication techniques that can be used to establish trust at the device level. The output points to the enhanced resistance to quantum and classical attackers that can make the solutions work in real-time application IoT environments such as smart healthcare, autonomous systems, and industrial automation. Overall, the quantum-enriched model of cryptographic key exchange is next-gen IoT ecosystem to be implemented subsequently.
