Re-otp Key Management Mechanism for the Cloud Data Security

Cloud storage is one of the most popular services techniques in cloud computing environment. A crucial problem to be addressed in the cloud storage system concerns the security mechanism of protecting the private data and sharing data with other users. Cloud storage services are inherently insecure as the management technique of the data in the cloud storage is controlled by third parties beyond the reach of the data owner. The secrets keys used for obfuscation are stored in a secure location (cloud location) while obfuscated data is stored in the cloud. In this approaches, the data is as secure as its corresponding keys. However, this still brings a challenging issue where a user needs to manage a large number of (secret) keys in such a way that they are guarded against all types of adversaries, and should be as highly available as cloud storage services. In this paper, we present a Re-key management technique to protect the security of user data and enforce the data access control. In our scheme is suitable for personal cloud storage and especially available to enterprise users to management their key of different kinds of resources. We describe the heritage system model, the details of the key management service and a prototype implementation.
