A Secure Data Deduplication Scheme for Cloud Storage
Original language description
As more corporate and private users outsource their data to cloud storage providers, recent data breach incidents make end-to-end encryption an increasingly prominent requirement. Unfortunately, semantically secure encryption schemes render various cost-eective stor- age optimization techniques, such as data deduplication, ineective. We present a novel idea that dierentiates data according to their popular- ity. Based on this idea, we design an encryption scheme that guarantees semantic security for unpopular data and provides weaker security and better storage and bandwidth benets for popular data. This way, data deduplication can be eective for popular data, whilst semantically secure encryption protects unpopular content. We show that our scheme issecure under the Symmetric External Decisional Diffie-Hellman Assumption in the random oracle model.
