Internet of Things (IoT) devices are becoming increasingly ubiquitous in many sectors, resulting in a significant increase in the number of IoT devices. Due to the increasing availability of high-capacity storage devices at cost-effective prices, attackers can feasibly store intercepted data now and decrypt it later using advanced quantum computing techniques. In this paper, an innovative approach is presented for the efficient implementation of Post-Quantum Cryptography (PQC) in extreme edge IoT nodes. This strategy leverages context-aware security (CAS), a strategy that allows the systems to react to threats based on information collected from it environment. The use of CAS allows the network to adjust its security measures based on real-time events detected by sensors. Furthermore, the risk posed by quantum computer attacks has been assessed, leading to the design incorporating encryption algorithms that are currently considered resistant to quantum computing attacks. This paper proposes the implementation of a prototype network that employs CAS and utilizes PQC.

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.

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 emergence of quantum computing seriously threatens the security of legacy cryptographic protocols in consumer electronics devices based on the Internet of Things (IoT). These are essential components of mission-critical infrastructures, such as industrial control systems, smart grids, and healthcare. In particular, this work examines how to strengthen the resistance of the IoT to classical and quantum-based cyberattacks by combining deep learning methods with post-quantum cryptography (PQC). To protect key exchange, encryption, and authentication processes in IoT-consumer devices, we will continue to use quantum-resistant cryptographic algorithms, including lattice-based, hash-based, and code-based cryptography. To provide real-time anomaly detection and response capabilities, we suggest a hybrid security framework combining PQC with deep learning-based intrusion detection systems. Our methodology ensures secure communications and data exchanges linked to quantum attacks in the future within IoT systems while leveraging continuous learning over time to allow Intrusion Detection System (IDS) models to adapt to new attack vectors. We suggest optimized algorithms for PQC solutions that are lightweight and suitable for deployment in edge computing nodes and Internet of Things devices, considering the resource-constrained IoT situations where PQC implementation would be difficult. Through comparative studies and simulations, we demonstrate how our integrated PQC-deep learning framework offers an improved IoT security solution that could safeguard vital systems in a world powered by quantum technology. The results shows the key generation time which is 12.5ms, encryption/decryption time 25.3ms, latency 18.7ms, throughput 5000 operations/sec and energy consumption 2.4mJ.

The growth of quantum computing reveals a series of significant threats to cryptographic systems known today, such as RSA, ECC, and Diffie-Hellman, which are extremely important for Internet security, but are threatened by the increase in possible quantum attacks. The area of public and private key cryptography is vast. Therefore, this article addresses post-quantum cryptography (PQC) algorithms and the challenges of implementing them in Internet of Things (IoT) devices, given the difficulty of application due to restricted resources, such as RAM and clock speed . To this end, we will discuss the need for standardization of algorithms considering low-resource IoT devices, prioritizing RAM over ROM, meeting the needs of low-memory devices, which are lighter. The National Institute of Standards and Technology (NIST) has validated four cryptographic systems that are secure against quantum attacks. We analyze the implications of these systems on the infrastructure of current networks and will compare in detail these algorithms and their respective strengths, weaknesses, and trade-offs. We evaluate the feasibility of post-quantum encryption (PQC) algorithms in resource-constrained IoT devices using the ESP-WROOM-32 microcontroller. Three cryptographic schemes were implemented and compared.
The rapid proliferation of Internet of Things (IoT) devices presents critical cybersecurity challenges, as traditional cryptographic methods often fail to provide both robust security and operational efficiency in resource-constrained environments. This paper introduces Adaptive Quantum Cryptography (AQC), a novel framework designed to secure next-generation IoT networks against evolving classical and quantum-computing threats. The AQC framework synergistically integrates Quantum Key Distribution (QKD) for unbreakable key exchange, Quantum Random Number Generators (QRNGs) for high-entropy key generation, and Post-Quantum Cryptography (PQC) for quantum-resistant data encryption. A key feature of the system is its dynamic adaptation mechanism, which leverages artificial intelligence to intelligently select and adjust cryptographic protocols in real-time based on current network conditions, device computational capabilities, and identified threat levels. This ensures optimal security without imposing excessive overhead on IoT devices. Our comprehensive experimental evaluation demonstrates that the AQC framework significantly outperforms classical techniques, achieving a 70% improvement in key exchange efficiency, a 50% reduction in computational load, and a 95% resilience rate against quantum-based attacks. By providing forward secrecy and robust authentication, the proposed AQC framework offers a scalable, energy-efficient, and future-proof security solution, paving the way for resilient and trustworthy IoT ecosystems in the post-quantum era.
