A Review On Assured Deletion Of Cloud Data Based On Cryptography

In the cloud computing environment, storage is used for users to provide data outsourcing services. After users outsource data to the cloud, privacy protection has become a key concern. As far as we know, there is no systematic analysis of the assured deletion of cloud storage data based on cryptography from the perspective of having a third-party key management center (TKMC) and no TKMC. Our work focuses on analyzing and evaluating the finegrained, safety, and performance of these schemes, and we also point out that researches can use trusted computing to securely strengthen TKMC in the future, making assured deletion more secure and reliable.
