云存储中支持安全去重的数据完整性验证方法
Data Integrity Verification Method with Secure Deduplication in Cloud Storage
摘要
Abstract
For the secure issues of outsourced data in cloud storage,a new method of data integrity verification is proposed,which can support secure deduplication and public verification.The method combines the advantages of Proofs of Ownership(POW) and Proofs of Retrievability (POR),and achieves client-side secure deduplication and data integrity verification simultaneously,in which data block,random sampling and dynamic coefficient are used.By introducing bilinear pairings and erasure codes,users can infinitely verify whether the data is intact in cloud storage.If the data is damaged,users can repair it with erasure codes.To achieve privacy preserving,the technology of random masking is introduced,which can hide the information of users' data effectively.Analysis results show that the proposed method not only can assure the security and integrity of data stored in cloud storage,but also can efficiently reduce the computing cost and communication cost.关键词
