Cloud Storage with Added Data Security and Integrity

Reshmi Das M V, R Charanya

Abstract: Cloud storage helps user to store and access data over the internet irrespective of their location. As the cloud services are cheap and very easy to access there has been a drastic increase in cloud users all over the world. These cloud providers provide storage services facilitating fast access to large set of data, but there have been many security concerns which include data privacy, confidentiality and integrity. Studies show that user-s data might get compromised over the cloud as existing cloud service providers do not assure data privacy to their users. To protect user-s data stored over cloud this work proposes a cloud storage system which will provide encrypted storage for their data. RC6 encryption is used in this system to provide data encryption over cloud. As the data are stored in encrypted format, it is difficult to misuse others data. Also SHA3-keccak algorithm is added to ensure data integrity. With added integrity user will be able to identify if his data is modified or corrupted disabling inappropriate contents from getting downloaded to the system.
