A storage security architecture based on distributed storage is presented to deal with the data security in the cloud storage systems and applications.The mechanism of safety management and transmission of storage data are realized by layer through the use of information dispersal algorithms(IDA),distributed storage management,and data restore methods.The method improves the high availability of data by examining the usable slices,recalculating all data in data segment,and recovering damaged data according to mutual redundant storage equipment data.Protection measures from the data transmission to storage are taken to ensure safety between cloud storage layer and other layers such that effective data protection is realized.Simulation tests show that the architecture improves the overall performance of the system while ensures the high security of data.
