英文摘要	User data integrity across cloud storage can be verified by a cooperative dynamic data possession (CDDP) scheme presented here. A layered Hash index is used to aggregate the response messages of the cloud storage service providers into one message with the communications among the cloud service providers, the organizer and a trusted third party used to verify the data possession. Dynamic updates of the user data, such as data modifications, data insertions, and data deletions, only require updating of the index records and the data block tags in the index-Hash table. This scheme reduces the computation times and resists forgery attacks. © 2017, Tsinghua University Press. All right reserved.
