Group User Revocation and Integrity Auditing of Shared Data in Cloud Environment
2015
International Journal of Computer Applications
Preserved Fulltext
A new user can be added into the group and an existing group member can be revoked by preserving privacy including data backup based on vector commitment and verifier-local revocation group signature. ...
In this paper, there will be auditing the integrity of shared data with dynamic groups in cloud. ...
To avoid these attacks and also to provide public verifiable for dynamic outsourced data, a new framework for verifiable database with efficient update from vector commitment was proposed. ...

Verifiable dynamic SSE requires the server to give a proof of the result of the search query. The data owner can verify this proof efficiently. ...
In this paper, we have proposed a generic publicly verifiable dynamic SSE (DSSE) scheme that makes any forward private DSSE scheme verifiable without losing forward privacy. ...
Though a VDSSE scheme supports update, we do not verify whether the cloud updates the database correctly or not. We only want to get the correct result with respect to current state of the database. ...

The content of the database is publicly verifiable such that any party in possession of some value s and a proof π can check that s is indeed in the database. ...
The stream is verifiable in the sense that the server can neither change the order of the elements nor manipulate them. The client may also retrieve data from the database and update them. ...
This scheme supports an exponential number of elements, efficient updates, and the items in the database are publicly verifiable. ...
