Enhancing Defense Supply Chain Security and Efficiency through Blockchain-Enabled IoT Integration

The implementation of blockchain-enabled IoT in supply chain management enhances security, transparency, and efficiency. This paper presents a private blockchain framework tailored for defence supply chain applications, utilizing Hyperledger Fabric for decentralized data management. The implemented system ensures secure data transactions, real-time monitoring, and automated contract enforcement using smart contracts. Through simulation and testing, the model demonstrated an improvement in data integrity and security, reducing unauthorized access incidents by 35%. The proposed system addresses the vulnerabilities of traditional supply chains by integrating blockchain's immutability and IoT's real-time tracking, providing a robust solution for secure logistics management.
