Cloud storage Audit Scheme Based on ORAM and SGX
Haifeng Ma, X Wang · 2023
With the increasing demand for Cloud storage, user access mode protection has also begun to come into people's sight. This scheme combines software protection expansion and Ring ORAM to verify the integrity of cloud data. While hiding the user's access mode and behavior to the ECS, Ring ORAM's Binary tree data structure combined with MHT (Merkel Merkle tree) is used to calculate the data root value to complete the audit, avoiding the generation of data labels The verification of Data integrity, the inspection of untrusted TPA audit results and other cumbersome audit processes, while hiding the user access mode, reduce the audit computing overhead.
