Quantum-Resilient Blockchain with Big Data Analytics for IoT Security in Smart Infrastructure

This research paper explores the integration of quantum-resilient blockchain technology with big data analytics to enhance security in Internet of Things (IoT) based smart infrastructure systems. As IoT devices continue to grow in smart cities, healthcare, transportation, and industrial environments, traditional security mechanisms face challenges from cyberattacks and future quantum computing threats. The proposed approach focuses on using quantum-resistant cryptographic techniques within blockchain networks to ensure secure communication, decentralized data management, and protection against emerging quantum attacks. Additionally, big data analytics is utilized to monitor, process, and analyze large volumes of IoT-generated data for intelligent threat detection and system optimization. The study highlights the importance of combining blockchain, quantum-safe security, and data analytics to build scalable, secure, and efficient smart infrastructure systems for future digital environments.
