Dynamic Flexible Multiple-Replica Provable Data Possession in Cloud
Yaling Zhao, Shuquan Li · 2020
With the rapid growth of data and development of cloud storage services, more and more individuals and organizations tend to outsource their data to the cloud environment. Cloud storage brings much convenience to people, but also brings a series of security issues, such as the integrity and reliability of data in the cloud. Based on the characteristics of multi branch tree, a dynamic flexible multiple-replica provable data possession scheme is proposed. The scheme can not only ensure the integrity and reliability of multi ple copies and realized the verification of any number of copies, but also support the dynamic update operation. In addition, the scheme also supports third party audit (TPA) and user privacy protection. The experimental results show that the scheme has high efficiency.
