Abstract: ABSTRACT Development of a Quantum Computing Framework for IoT Device Data Security System for Communication Application A quantum computing framework system is being developed for the IoT device data security system for communication purposes in this patented work and it is the outcome of the funded project. The rapid growth of IoT devices in critical sectors such as agriculture has created an urgent need for advanced cybersecurity solutions capable of protecting sensitive information from modern and future cyber threats. This research project focused on developing a robust post-quantum cryptographic (PQC) framework to secure IoT-based agricultural systems, particularly agri-bots used in precision farming applications. The proposed framework aimed to ensure data confidentiality, integrity, and authenticity while addressing the vulnerabilities posed by the emergence of quantum computing. To achieve this, lattice-based cryptographic algorithms such as Kyber for secure key exchange and Dilithium for digital signatures were integrated to establish quantum-resistant communication channels. The framework was carefully designed to maintain strong security while ensuring energy efficiency and scalability for resource-constrained IoT environments. The first phase of the project concentrated on developing a standardized security framework for IoT communications using post-quantum cryptographic techniques. Kyber-based authenticated key exchange and Dilithium-based digital signatures were implemented to secure data exchanges between IoT devices and servers. Industry-standard X.509 certificates signed using Dilithium-3 were incorporated to ensure data authenticity and integrity. In the second phase, a post-quantum TLS framework was developed by replacing traditional cryptographic schemes such as RSA and ECC with quantum-resistant alternatives. This enabled secure client-server communication through protected handshakes while ensuring confidentiality, authentication, and resilience against future quantum-enabled attacks. Comprehensive security evaluations confirmed the framework’s effectiveness in creating secure communication channels suitable for next-generation IoT systems. The third objective focused on enhancing data confidentiality through AES-256 encryption combined with secure PRNG-based key generation techniques. AES-256 was selected due to its strong encryption capability and suitability for lightweight IoT environments. A Python-based pseudo-random number generator compliant with NIST recommendations was implemented to securely generate cryptographic keys. The fourth phase involved extensive performance and security analysis of the proposed post-quantum cryptographic mechanisms. The Kyber key exchange mechanism was evaluated on ARM Cortex-M4 and Intel platforms, while Dilithium3 digital signature operations were analyzed on AMD Ryzen 7 systems. Parameters such as key generation time, certificate signing request generation, verification delay, and energy consumption were measured. Experimental results demonstrated that post-quantum cryptographic protocols can be efficiently deployed in IoT environments without significantly affecting system performance or power consumption. The developed framework has major implications for the agriculture sector, especially in precision farming applications where agri-bots and IoT sensors continuously exchange critical data. By integrating quantum-resistant encryption mechanisms, the framework ensures secure real-time communication, minimizes the risk of cyber-attacks, and protects agricultural information from unauthorized access. As quantum computing technologies continue to evolve, conventional encryption methods may become vulnerable, making post-quantum cryptography essential for future cybersecurity infrastructures. The successful implementation of Kyber and Dilithium algorithms within IoT systems demonstrates the practical feasibility of post-quantum security solutions for real-world applications. This research provides a scalable and future-proof approach for safeguarding IoT ecosystems and offers valuable insights for both academic research and industrial deployment in the rapidly expanding digital and connected world.
