Abstract: The rapid growth of the Industrial Internet of Things (IIoT) has led to the continuous generation of large volumes of time-series data from sensors and industrial devices. These data streams are commonly stored and processed in cloud platforms to enable scalability, remote monitoring, and advanced analytics. However, storing sensitive industrial data in cloud environments introduces significant privacy and security risks, including unauthorized access and data breaches. To address these challenges, a secure data storage and sharing framework for time-series data streams in IIoT environments is proposed. The system employs a symmetric homomorphic encryption technique that enables analytics to be performed directly on encrypted data without revealing the original information. Additionally, the framework introduces fine-grained access control mechanisms that allow data owners to selectively share encrypted data streams with authorized third-party services. A verification mechanism based on message authentication ensures data integrity and authenticity during data processing and sharing. The proposed SmartCrypt-based approach enhances data confidentiality while maintaining efficient query processing and analytics capabilities. Experimental analysis demonstrates that the system improves query performance and throughput compared to existing encrypted data stream processing solutions, making it suitable for secure and scalable IIoT data management.
