Secure and efficient proof of ownership for deduplicated cloud storage

摘要: The rapid increment in volume of outsourced data has raised an issue management for Cloud Storage Server. To solve this issue, Deduplication, a compression technique was introduced which avoids duplicate storage. However, Deduplication is vulnerable to malicious access genuine Clients' files. An adversary can get file by learning small piece knowledge about the file. In paper, we propose secure and efficient Proof Ownership Deduplicated Storage. Our approach employs random matrix based challenges retrieved from We evaluate security efficiency our theoretical proofs experimental results.
