Currently, we rely on cryptographic algorithms such as elliptic curve cryptosystems (ECCs) as basic building blocks to secure the communication in the IoT. However, public key schemes like ECC can easily be broken by the upcoming quantum computers. Due to recent advances in quantum computing, we should act now to prepare the IoT for the quantum world. In this article, we focus on the current state of the art and recent developments in the area of quantum-resistant cryptosystems for securing the IoT. We first demonstrate the impacts of quantum computers on the security of the cryptographic schemes used today, and then give an overview of the recommendations for cryptographic schemes that can be secure under the attacks of both classical and quantum computers. After that, we present the existing implementations of quantum-resistant cryptographic schemes on constrained devices suitable for the IoT. Finally, we give an introduction to ongoing projects for quantum-resistant schemes that will help develop future security solutions for the IoT.
The rapid advancements in quantum computation pose significant threats to traditional cryptographic systems, such as those used in the Internet of Things (IoT). RSA and methods like Elliptic Curve Cryptography (ECC) are particularly vulnerable to quantum algorithmic techniques, such as Shor’s and Grover’s algorithms. This paper focuses on the analysis of cryptographic models based on quantum technologies, with special emphasis on IoT security. It examines how both symmetric and public-key cryptography are affected by quantum comput-ing—highlighting vulnerabilities in symmetric schemes to Grover’s algorithm and in public-key systems like ECC to Shor’s algorithm. Significant focus is placed on the advancement of quantum-resistant ECC, with an in-depth evaluation of its effectiveness, security capabilities, and suitability for IoT applications. This work also compares various methods for implementing quantum-enhanced ECC, considering both software and hardware solutions. Furthermore, the paper explores emerging hybrid systems that integrate classical and quantum-resistant encryption to offer enhanced security in transitional scenarios. Lastly, it outlines potential research avenues for developing new techniques to protect future IoT networks from quantum-based attacks.
Although quantum computing is still in its nascent age, its evolution threatens the most popular public-key encryption systems. Such systems are essential for today's Internet security due to their ability for solving the key distribution problem and for providing high security in insecure communications channels that allow for accessing websites or for exchanging e-mails, financial transactions, digitally signed documents, military communications or medical data. Cryptosystems like Rivest-Shamir-Adleman (RSA), elliptic curve cryptography (ECC) or Diffie-Hellman have spread worldwide and are part of diverse key Internet standards like Transport Layer Security (TLS), which are used both by traditional computers and Internet of Things (IoT) devices. It is especially difficult to provide high security to IoT devices, mainly because many of them rely on batteries and are resource constrained in terms of computational power and memory, which implies that specific energy-efficient and lightweight algorithms need to be designed and implemented for them. These restrictions become relevant challenges when implementing cryptosystems that involve intensive mathematical operations and demand substantial computational resources, which are often required in applications where data privacy has to be preserved for the long term, like IoT applications for defense, mission-critical scenarios or smart healthcare. Quantum computing threatens such a long-term IoT device security and researchers are currently developing solutions to mitigate such a threat. This article provides a survey on what can be called post-quantum IoT systems (IoT systems protected from the currently known quantum computing attacks): the main post-quantum cryptosystems and initiatives are reviewed, the most relevant IoT architectures and challenges are analyzed, and the expected future trends are indicated. Thus, this article is aimed at providing a wide view of post-quantum IoT security and give useful guidelines to the future post-quantum IoT developers.
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 article also addresses practical considerations for industry adoption, including development lifecycle integration, governance frameworks, and compliance requirements. Through examination of real-world implementation scenarios, this article establishes a successful quantum-resistant IoT security required for a balanced approach between immediate protective measures and long-term strategic planning, providing organizations with actionable guidelines for securing their IoT infrastructure against quantum threats.
