In cloud computing,data service outsourcing relieves the data owners of the burden of local data storage and maintenance.However,it also eliminates their physical control of the storage dependability and security,which makes the outsourced data assurances in cloud computing a very challenging and potentially formidable task.Based on the overall study of the recent researches on data storage security,it introduced the architecture of cloud data storage firstly.And studied the state-of-the-art schemes from proofs of retrievability and provable data possession.Then,this paper discussed the function design in protocol based on public verification,homomorphic authenticators,data dynamics,data privacy protection,batch auditing and multiple-server environment.Furthermore,made some comparisons of functions and the complexity in different protocols in tables.At last,summarized and discussed the further direction of research.
