Data deduplication, an effective data compression approach that exploits data redundancy, partitions large data objects into smaller parts, called chunks, represents these chunks by their fingerprints (i.e., generally a crypto-graphic hash of the chunk data), replaces the duplicate chunks with their fingerprints after chunk fingerprint index lookup, and only transfers or stores the unique chunks […]
ALG-DEDUPE FOR CLOUD BACKUP SERVICES OF PERSONAL STORAGE
In this abstract, we propose ALG-Dedupe, an Application-aware Local-Global source deduplication scheme that not only exploits application awareness, but also combines local and global duplication detection, to achieve high deduplication efficiency by reducing the deduplication latency to as low as the application-aware loc al de-duplication while saving as much cloud storage cost as the application-aware […]
MRSE SCHEME OVER ENCRYPTED CLOUD DATA FOR PRIVACY PRESERVING
To protect data privacy and combat unsolicited accesses in the cloud and beyond, sensitive data, e.g., emails, personal health records, photo albums, tax documents, financial transactions, etc., may have to be encrypted by data owners before outsourcing to the commercial public cloud; this, however, obsoletes the traditional data utilization service based on plaintext keyword search. […]
AN EFFICIENT MULTI-KEYWORD RANKED SEARCH SCHEME OVER ENCRYPTED CLOUD DATA
In this abstract, for the first time, we define and solve the problem of multi-keyword ranked search over encrypted cloud data (MRSE) while preserving strict system-wise privacy in the cloud computing paradigm. Among various multi-keyword semantics, we choose the efficient similarity measure of “coordinate matching”, i.e., as many matches as possible, to capture the relevance […]
A NOVEL PUBLIC AUDITING MECHANISM FOR THE INTEGRITY OF SHARED DATA WITH EFFICIENT USER REVOCATION IN THE CLOUD
In this abstract, we propose Panda, a novel public auditing mechanism for the integrity of shared data with efficient user revocation in t he cloud. In our mechanism, by utilizing the idea of proxy re-signatures, once a user in the group is revoked, the cloud is able to re-sign the blocks, which were signed by […]
PUBLIC AUDITING FOR SHARED DATA WITH USER REVOCATION IN THE CLOUD USING PANDA
Cloud providers promise a more secure and reliable environment to the users, the integrity of data in the cloud may still be compromised, due to the existence of hardware/ software failures and human errors. An important problem we need to consider is that the re- computation of any signature during user revocation should not affect […]
A REVOCABLE MULTI-AUTHORITY CP-ABE SCHEME
In this abstract, we first propose a revocable multi-authority CP-ABE scheme, where an efficient and secure revocation method is proposed to solve the attribute revocation problem in the system. Our attribute revocation method is efficient in the sense that it incurs less communication cost and computation cost, and is secure in the sense t hat […]
SECURE AUTHORIZED DEDUPLICATION USING A HYBRID CLOUD APPROACH
Data deduplication is a specialized data compression technique for eliminating duplicate copies of repeating data in storage. The technique is used to improve storage utilization and can also be applied to network data transfers to reduce the number of bytes that must be sent. To protect the confidentiality of sensitive data while supporting deduplication, the […]
MULTI-AUTHORITY ACCESS CONTROL SCHEME FOR SECURE CLOUD STORAGE
In multi-authority cloud storage systems, users’ attributes can be changed dynamically. A user may be entitled some new attributes or revoked some current attributes. And his permission of data access should be changed accordingly. Ciphertext-Policy Attribute-based Encryption (CP-ABE) is regarded as one of the most suitable technologies for data access control in cloud storage, because […]
A NOVEL ARCHITECTURE FOR INTEGRATES CLOUD DATABASE SERVICES WITH DATA CONFIDENTIALITY AND EXECUTING CONCURRENT OPERATIONS ON ENCRYPTED DATA
In this abstract, we propose SecureDBaaS as the first solution that allows cloud tenants to take full advantage of DBaaS qualities, such as availability, reliability, and elastic scalability, without exposing unencrypted data to the cloud provider. The architecture design was motivated by a threefold goal: to allow multiple, independent, and geographically distributed clients to execute […]
