Abstract
Cloud computing users can share data files among dynamic groups in the cloud. A challenging issue at present is lag in guaranteeing the security for sharing the data file. The owner can upload the data files in the cloud by rend the services from the cloud service providers. According to the service level agreement the third party auditor will verify the uploaded files before accessing the data files from the cloud. The key distribution can be secured by providing a secure data sharing scheme for dynamic groups. The authorized application will generate the secret key to access the file. First the third party auditor will authorize the file request to be accessed by the user. Secondly, the authorized application will send the secret key to the user only when the uploaded files are verified. When a new user joins in the group or a user is revoked from the group. The previous users need not update their private keys. Finally the revoked users cannot get the original data file when they left the dynamics groups in the cloud.
