Abstract:

Data reduplication is a process for eliminating imitation print of statistics, and has been extensively used in cloud storeroom to lessen storage room and upload bandwidth. Although convergent encryption has been far adopted for secure reduplication, a vital issue of making convergent encryption practical is to powerful and constantly run a huge quantity of convergent keys. We first begin a baseline advance in which each client holds an independent master key for encrypting the convergent keys and outsourcing them to the cloud. Though, such a baseline key group method generate an huge number of keys with the high number of users and fulfil users to dedicatedly guard the master keys. To this end, we plan De key, a new construction in which users do not need to handle any keys on their personal but as a substitute strongly dispense the convergent key shares across several servers. Security analysis demonstrates that De key is safe in terms of the definition particular in the future security model. As a evidence of concept, we apply De-key using the Ramp secret sharing scheme and reveal that De-key incurs partial overhead in practical environments.
