Abstract: Cloud computing is promising and considered next generation technology for computing. The current cloud storage auditing models require the client to update his secret keys in each time period which bring in local burdens to the client. The aim of the project is to make the key updates transpicuous to the client and present a new model for auditing cloud storage with provable outsourcing of updated keys. In this model, the key updates are sent to a third party auditor (TPA) who reduces the local burden on the client. In addition, the TPA will audit whether the files in cloud are stored correctly by a challenge-response protocol between the cloud and TPA at regular time. The proposed paradigm permits the client to authenticate the validity of the encrypted secret key produced by the TPA for uploading data to the cloud.

Keywords: cloud computing; encryption; decryption; multi key encryption algorithm.
