Providing Secure Encryption and Auditing of Content on Public Cloud

Vrushali A. Kumawat, Prof. Rakesh S. Shirsath

Abstract


Cloud computing is one of the emerging technology, as it
provides huge storage of information which is then requested
by the end user. This pairing free system ensures security and
integrity of the data which is stored on to the cloud. The
susceptible information is first encrypted and then uploaded
on to the cloud and that information is half decrypted by the
cloud and given to the requested end user for the full
decryption process. The system generates a single encryption
key for multiple user having similar access control policies,
who are requesting for particular data whereas previous
system was supporting single key for an individual. Therefore
time for accessing same data by multiple requesters will
reduce automatically and also key management will be easy.
As only half decryption process is done on to the cloud
therefore confidentiality of the data is maintained over cloud.
After uploading of data the authentication is maintained by
encryption whereas the integrity is ensured by auditing
technique. In the case of any changes done to the uploaded
data, will generate an alert message for the data owner. If
considered the properties of confidentiality and integrity with
respect to cloud then definitely there will be takeoff in its
performance graph as compared to the existing system.
