چکیده

Encrypting data on the client-side before uploading it to cloud storage is essential for protecting users’ privacy. However client-side encryption is at odds with the standard practice of deduplication in cloud storage services. Reconciling client-side encryption with cross-user deduplication has been an active research topic. In this paper, we present the first secure cross-user deduplication scheme that supports clientside encryption without requiring any additional independent servers. We demonstrate that our scheme provides better security guarantees than previous work. We also demonstrate that its performance is reasonable via simulations using realistic datasets.

Separating indexes from data: a distributed scheme for secure database outsourcing

Database outsourcing is an idea to eliminate the burden of database management from organizations. Since data is a critical asset of organizations, preserving its privacy from outside adversary and untrusted server should be warranted. In this paper, we present a distributed scheme based on storing shares of data on different servers and separating indexes from data on a distinct server. Shamir...

Block-level De-duplication with Encrypted Data

Deduplication is a storage saving technique which has been adopted by many cloud storage providers such as Dropbox. The simple principle of deduplication is that duplicate data uploaded by different users are stored only once. Unfortunately, deduplication is not compatible with encryption. As a scheme that allows deduplication of encrypted data segments, we propose ClouDedup, a secure and effic...

Secure Deduplication of Encrypted Data: Refined Model and New Constructions

Cloud providers tend to save storage via cross-user deduplication, while users who care about privacy tend to encrypt their files on client-side. Secure deduplication of encrypted data (SDoE) which aims to reconcile this apparent contradiction is an active research topic. In this paper, we propose a formal security model for SDoE. We also propose two single-server SDoE protocols and prove their...

Provable Ownership of Encrypted Files in De-duplication Cloud Storage

The rapid adoption of cloud storage services has created an issue that many duplicated copies of files are stored in the remote storage servers, which not only wastes the communication bandwidth for duplicated file uploading, but also increases the cost of security data management. To solve this problem, client-side deduplication was introduced to avoid the client from uploading files already e...

A Survey on Efficient Protocol to Prevent Deducpilcation of Data in Cloud Environments in a Safe and Secure Manner

Due to the increasing usage of cloud humongous amount of data is getting stored in the cloud data servers. But this also leads to lots of duplicate data over a period of time. While existing systems have focused on the duplication removal also known as deduplication, they have done so only in one server and also not considered safety and security. This means that residual data left in data serv...
