Time Based Re-Encryption In Unreliable Clouds
|Name||Time Based Re-Encryption In Unreliable Clouds|
—With rapid development of cloud computing, more and more enterprises will outsource their sensitive data for sharing in a cloud. To keep the shared data confidential against untrusted cloud service providers (CSPs), a natural way is to store only the encrypted data in a cloud. The key problems of this approach include establishing access control for the encrypted data, and revoking the access rights from users when they are no longer authorized to access the encrypted data. In this paper the time based re-encryption scheme is proposed which is based on the internal server of cloud server.
