SECURE AND EFFICIENT IOT DATA MANAGEMENT IN CLOUD ENVIRONMENTS VIA FORWARD-SECURE ATTRIBUTE-BASED SEARCHABLE ENCRYPTION

In this work, we proposed a Forward-Secure Attribute-Based Searchable Encryption (FS-ABSE) framework to enable secure and efficient management of IoT data in cloud environments. The system integrates attribute-based encryption, searchable encryption, and forward security, ensuring that data remains confidential and accessible only to authorized users, even in the event of key compromise. The framework supports secure keyword search over encrypted data through a trapdoor mechanism, enforces fine-grained access control based on user attributes, and maintains efficient performance suitable for large-scale IoT deployments. Experimental results confirm that FS-ABSE effectively balances security, privacy, and search efficiency, making it a practical solution for cloud-assisted IoT systems.
