摘要：Today’s modern world largely depends on the cloud computing ,large set of users depends on cloudsystem ,in a cloud systems with fixed no of members ,the main problem is The direct technique which permits a currentclient to download the some portion of shared data and re-sign it with client key it is wasteful process because of thebig size of shared data in the cloud. Enhanced auditing, propose a novel open auditing system for the checking the ofintegrity of the data. By using the possibility of automatic re-signing key, it permit the cloud to leave obstructs forexisting users amid client revocation, so that current users don't have to download and re-sign pieces of data fromanyone else. What's more, an third party auditor is constantly ready to review the integrity of shared data withoutrecovering the whole data from the cloud, regardless of the possibility that some piece of shared data has been resignedby the cloud itself. Trial comes about demonstrate that the mechanism can essentially enhance the proficiency of clientrepudiation.
