The Internet of Things (IoT) now underpins critical systems like healthcare monitors, smart home, smart grids, automotive V2V & V2X networks, and industrial controls but it still relies on classical cryptography, whose security assumptions are vulnerable to quantum computers. A large quantum computer could run Shor’s algorithm to break RSA/ECC and use Grover’s algorithm to accelerate brute-forcing of symmetric keys, undermining the confidentiality and authentication of data in these IoT applications. Researchers have proposed quantum cryptographic solutions. Quantum key distribution (QKD) and quantum random number generators (QRNGs) exploit quantum mechanics to detect eavesdropping and deliver provably secure key material. For example, chip-scale QRNGs can be embedded in IoT sensors to generate true random keys, boosting resistance to brute-force attacks. These quantum techniques provide information-theoretic secrecy, for instance, QKD-generated keys have been used to authenticate smart-grid SCADA. However, most IoT devices are resource-constrained, making direct deployment of conventional QKD hardware challenging. Post-quantum cryptography (PQC) complements quantum methods by providing algorithms such as lattice-based, hash-based that resist quantum attacks on existing hardware. Standardized PQC can be deployed via software updates on legacy IoT nodes, enabling scalable and quantum-safe security within current constraints. Researchers are exploring lightweight PQC for connected cars and e-health sensors. Hybrid approaches combining QKD/QRNG with PQC offer a layered defense. Since QKD protocols are regarded as ‘future-proof’ and PQC standards mature, their combined use will be essential for robust, quantum-safe IoT security. Miniaturizing quantum components such as integrated QKD/QRNG modules and optimizing lightweight PQC schemes for low-power IoT devices are future research directions to secure IoT networks.
The security of the Internet of Things (IoT) is a key worry since it deals with personal data that must be dependable and can be used dangerously to control and manipulate device operations. In addition, the data generating process is heterogeneous, and the data is enormous in bulk, requiring complicated management. Quantum IoT, or Quantum Computing and IoT, is a notion of higher security design that utilizes quantum-mechanical principles on IoT security management. On the one hand, IoT is beneficial to us, but it also poses several major security risks, such as data leaks, side-channel attacks, malware, and data authentication. Classical cryptographic techniques, such as the Rivest-Shamir-Adleman (RSA) algorithm, perform admirably on traditional machines. However, quantum computing, which has enormous processing capacity and is more than capable of readily breaking current cryptographic algorithms, is steadily gaining traction. As a result, even before quantum computers are commercially available, we must create post-quantum cryptography algorithms to protect our systems from security breaches. Lattice-based cryptography, as a possible option for the future post-quantum cryptography standard, has the features of strong security guarantees and great efficiency, making it ideal for IoT applications. We discuss the benefits of lattice-based cryptography and its implementations for IoT devices in this study.
Securing Internet of things is a major concern as it deals with data that are personal, needed to be reliable, can direct and manipulate device decisions in a harmful way. Also regarding data generation process is heterogeneous, data being immense in volume, complex management. Quantum Computing and Internet of Things (IoT) coined as Quantum IoT defines a concept of greater security design which harness the virtue of quantum mechanics laws in Internet of Things (IoT) security management. Also it ensures secured data storage, processing, communication, data dynamics. In this paper, an IoT security infrastructure is introduced which is a hybrid one, with an extra layer, which ensures quantum state. This state prevents any sort of harmful actions from the eavesdroppers in the communication channel and cyber side, by maintaining its state, protecting the key by quantum cryptography BB84 protocol. An adapted version is introduced specific to this IoT scenario. A classical cryptography system ‘One-Time pad (OTP)’ is used in the hybrid management. The novelty of this paper lies with the integration of classical and quantum communication for Internet of Things (IoT) security.
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.
IoT devices use outdated secure methods that are vulnerable to quantum computer attacks, making quantum computing a huge security issue. As quantum computers get smarter, RSA and ECC may not be able to protect IoT networks as well.

Percent uses quantum algorithms like Shor’s and Grover’s to provide unbreakable safety. Records are protected and quantum technology is sent securely. The research evaluates many PQC algorithms for IoT systems. It uses computational energy, power savings, and scale troubleshooting. We propose integrating conventional and post-quantum encryption to make IoT networks more trustworthy and impenetrable. This study shows how important PQC is for protecting IoT settings against quantum-based attacks by securing key exchange, data, and device identification.
