Abstract :
Security for the data which is stored on the cloud by user is very important issue. User may expect some security for their data from the cloud service provider, there can be serious issues concerning data security between user and service provider. To solve this kind of issues, we can use third party as an auditor. Here we have analyzed different ways to ensure secure data storage in cloud. We are going to provide the security to the users data by using encryption technique. For this we are using the Advanced Encryption Standard algorithm for encryption and decryption. But when Cloud Service Provider has both encryption and decryption keys, there is threat to security and privacy of data. CSP may pass the user data without users knowledge. For auditing we are introducing Third Party Auditor. Here the data will be encrypted at user side and will be in encrypted form over network and to TPA. TPA will verify the data before storing it on the cloud. There are large numbers of users of cloud computing who are accessing and modifying the data and they need the reliable service provider who can provide complete security for their data. So the TPA will audit the data and check the data integrity of clients data. Hence user will have more elaborated view over his data privacy. Rutuja G. Kaple | Prof. S. B.
