Journal ArticleDOI
Secure Deduplication with Efficient and Reliable Convergent Key Management
TL;DR: This paper proposes Dekey, a new construction in which users do not need to manage any keys on their own but instead securely distribute the convergent key shares across multiple servers and demonstrates that Dekey incurs limited overhead in realistic environments.
Journal ArticleDOI
Securely Outsourcing Attribute-Based Encryption with Checkability
TL;DR: This work proposes a new Secure Outsourced ABE system, which supports both secure outsourced key-issuing and decryption and proposes an outsourced ABE construction which provides checkability of the outsourced computation results in an efficient way.
Journal ArticleDOI
A Hybrid Cloud Approach for Secure Authorized Deduplication
TL;DR: This paper makes the first attempt to formally address the problem of authorized data deduplication, and shows that the proposed authorized duplicate check scheme incurs minimal overhead compared to normal operations.
Journal ArticleDOI
Identity-Based Encryption with Outsourced Revocation in Cloud Computing
TL;DR: This paper introduces outsourcing computation into IBE for the first time and proposes a revocable IBE scheme in the server-aided setting and proposes another construction which is provable secure under the recently formulized Refereed Delegation of Computation model.
Journal ArticleDOI
An Efficient Public Auditing Protocol With Novel Dynamic Structure for Cloud Data
TL;DR: This paper proposes an efficient public auditing protocol with global and sampling blockless verification as well as batch auditing, where data dynamics are substantially more efficiently supported than is the case with the state of the art.
