Cyberattacks on the power grid serve as a reminder that while the smart Internet of Things (IoT) can help us control our lightbulbs, it also runs the risk of putting us in the dark if attacked. Many works of literature have recently attempted to address the issues surrounding IoT security, but few of them tackle the serious dangers that the development of quantum computing poses to IoT. Lattice-based encryption, a likely contender for the next post-quantum cryptography standard, benefits from strong security guarantees and great efficiency, making it well-suited for IoT applications. In this article, we list the benefits of lattice-based cryptography and the most recent developments in IoT device implementations. The Internet of Things (IOT) is a new technology that is anticipated to improve human lives. According to Cisco research, by 2020, there will be a vast array of IOT devices that will span every industry, including transportation, healthcare, and smart gadgets for every aspect of daily life. IOTs are improving user experience by making smart devices smarter and their services of high quality. The devices' unfettered access to the whole network makes the IOT's security issues more susceptible. The research paper will contribute to the presentation of a compiled report on the security issues with IOTs and the cryptographic techniques utilised to address them.
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.
The rapid growth of the Internet of Things (IoT) has connected billions of smart devices across healthcare, transportation, industrial automation, and smart home environments. While IoT has enhanced automation and data-driven decision-making, its widespread deployment has also increased the risk of cyberattacks. Conventional public-key cryptographic algorithms such as RSA and Elliptic Curve Cryptography (ECC) are vulnerable to future quantum computing attacks, particularly those based on Shor's algorithm. This paper proposes a Quantum-Resistant Cryptographic Framework (QRCF) for secure IoT communication using lattice-based cryptography integrated with lightweight authentication and efficient key management. The framework is designed to meet the computational limitations of IoT devices while ensuring long-term confidentiality and integrity. Performance evaluation demonstrates improvements in security resilience, authentication efficiency, and communication reliability compared with traditional cryptographic approaches. The proposed framework offers a scalable and future-ready solution for protecting IoT ecosystems in the post-quantum era.

This paper presents lightweight Post-Quantum Cryptography (PQC), identifying its importance for a shift from traditional cryptographic schemes, vulnerable to quantum threats, to efficient PQC algorithms. Lattice-based cryptography stands out owing to its small key sizes and computational efficiency, with CRYSTALS-Kyber and NTRU algorithms being substantial representatives for Internet of Things (IoT) applications. However, PQC implementation in IoT environments has various obstacles to overcome. Minimizing energy consumption, scalability, and hardware limitations remain key challenges for PQC smooth integration into these resource-constrained networks. The present review analyzes the state-of-the-art PQC, makes security and performance comparisons among leading algorithms, and evaluates optimization techniques aimed at reducing resource overheads. Algorithmic refinement, hardware acceleration, and hybrid cryptography are also discussed as methods for mitigating these challenges. The results indicate that continuous research and development efforts should be made to improve the PQC technologies, and thus achieve their practical deployment in IoT systems. Quantum threats in IoT will be, hence, prevented with the employment of secure and scalable IoT ecosystems in a post-quantum world.
The rapid proliferation of Internet of Things (IoT) devices has heightened concerns regarding their security and privacy. Conventional cryptographic methods underpinning IoT security are increasingly threatened by the emergence of quantum computing, which promises to break widely used encryption algorithms such as RSA and ECC. This paper explores post-quantum cryptographic (PQC) algorithms tailored to the resource-constrained nature of IoT environments. It analyzes lattice-based, hash-based, code-based, and multivariate polynomial cryptographic schemes as promising candidates for securing IoT communications against quantum attacks. The paper further discusses implementation challenges, performance considerations, and potential pathways for integrating PQC within existing IoT architectures. Empirical data on computational efficiency and security strength are also presented to guide future deployment.
