Secure Inter Organizational  File Sharing Using Block Chain

As industrial systems continue to evolve, edge devices are generating vast amounts of data on a daily basis. Despite this growth, most data remains confined to centralized data centers, creating significant challenges for secure data exchange across different domains. The emergence of decentralized edge computing and blockchain technology has brought transformative changes to smart logistics solutions. To meet the increasing demand for secure and efficient data sharing within logistics networks, we propose a decentralized Hierarchical Attribute-Based Encryption (HABE) scheme integrated with blockchain and edge computing. Our solution introduces a privacy-preserving encryption strategy that allows edge devices to securely transmit data to nearby cloud nodes for processing. Additionally, a blockchain-based data-sharing framework is developed, utilizing both edge and cloud storage to ensure decentralized access control. The system incorporates a Secure Hash Algorithm (SHA) to enhance authentication, enabling reliable and tamper-resistant verification of user access rights at the network edge. By combining HABE, blockchain, and SHA, the proposed architecture ensures strong privacy protection, secure data sharing, and improved authentication efficiency. Experimental evaluations demonstrate that the system significantly enhances data privacy, security, and sharing capabilities compared to conventional centralized models, making it highly suitable for advanced industrial logistics applications.
