A Review on Assured Deletion of Cloud Data Based on Cryptography
Guan Wang, Yehong Luo · Procedia Computer Science · 2021
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 fine-grained, 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.
