Cloud computing provides seemingly unlimited "Virtualized" resources to users as services across the whole Internet, while hiding platform and implementation details. Data de-duplication is one of important data compression techniques for eliminating duplicate copies of repeating data, used in cloud storage to reduce the amount of storage space and save bandwidth. To protect the confidentiality of sensitive data while supporting de-duplication, the convergent encryption technique has been proposed to encrypt the data before outsourcing. To protect data security, it makes the first attempt to formally address the problem of authorized data de-duplication.
