摘要：
In order to protect the security of the data stored in the cloud by group users, a data integrity verification scheme was designed which can protect the privacy of the group users. The scheme can efficiently detect the shared data in the cloud and support the dynamic updating of the data, and use the characteristic of the ring signature to hide the identity of the signer corresponding to the data block. That is, the third-party verifier can not spy on the users identity and other private information when validating. The aggregated approach is used to generate data labels, which reduces the storage cost of labels and supports the dynamic operation of group data, so that the users in the group can easily modify the cloud group data. © 2016, Editorial Board of Journal on Communications.
