Deduplication is a process in which the duplicate copies of data are eliminated. It is being used in cloud storage for reducing the storage space. The convergent encryption is used for handling the deduplication that manage the their keys in a efficient and secured manner. In this paper, the key management is achieved efficiently. Initially, in baseline approach the master keys are to be protected by each user since they hold independent master keys. Inorder to avoid this, Dekey is implemented in which user only distribute the convergent key instead of managing the master key. As a proof of concept, Secure sharing scheme is used in implementing Dekey in which secret is divided and shared among users.
