A Survey of Public Auditing for Shared Data Storage with User Revocation in Cloud Computing
[[abstract]]Cloud computing technology has matured, so cloud computing
produces a wide range of cloud service. Cloud storage
services are one of cloud services where cloud service
provider can provide storage space to customers. Because
cloud storage services bring a lot of convenience, many
enterprises and users store the data to the cloud storage.
However, the user will outsource data to the cloud storage
service, but the user is difficult to manage remote data in
the cloud. Therefore, how users verify data integrity is
a major challenge. In recent years, public audit is used
to verify data integrity by which the user allows other
to verify the user’s data. Because the feature of cloud
service allows users to communicate with each other on
the cloud platform, the cloud storage service allows the
data owner to share their data to other users. Therefore,
public auditing extends to the share data, so the original
operation becomes not the same including signature,
public audits, dynamic data and user revocation which
generates on the situation of shared data. In the paper,
we define the requirements of public auditing with shared
data and explain four representative approaches which
include analysis function, security, and performance requirements.
Finally, we provide some topics for future
research
