title = "Policy-Based De-duplication in Secure Cloud Storage",
abstract = "Reducing the amount of data need to be transferred, stored, and managed becomes a crucial for cloud storage. On the other hand, as user data are stored and processed by outsourced cloud provider, encryption becomes a necessary before updating data into the cloud. However, the above two goals are greatly opposed to each other. In order to solve the above conflict, a policy-based de-duplication proxy scheme is proposed in this paper. It suggests a policy-based de-duplication proxy scheme to enable different trust relations among cloud storage components, de-duplication related components and different security requirements. Further proposes a key management mechanism to access and decrypt the shared de-duplicated data chunks based on Proxy Re-encryption algorithms. This paper finally analyses the security of the scheme.",
