ISSCC: Integrated Service for Full-Process Delivery in Secure Cloud Computing

Secure cloud computing offers a range of services including storage, search, and computation, all of which have experienced ongoing performance advancements. However, seamlessly integrating these services into a unified “storage–search–computation” workflow remains challenging due to heterogeneous security mechanisms. For instance, searchable encryption, while effective for secure search, does not natively support computation over ciphertext. To address this gap, we propose ISSCC, an integrated service framework that seamlessly bridges storage, search, and computation in secure cloud environments. ISSCC employs searchable encryption to ensure secure data storage and search. To support post-search computation on retrieved results, ISSCC utilizes trusted execution environments instead of purely cryptographic approaches. We implement ISSCC on a real TEE-enabled cloud platform and conduct a comprehensive performance evaluation and security analysis. Experimental results demonstrate that ISSCC is both feasible and practical, delivering effective end-to-end services across the full “storage–search–computation” pipeline in secure cloud computing.
