Research and Development of Provable Data Integrity in Cloud Storage
Tan Shuan · Chinese Journal of Computers · 2015
With the advent of cloud storage model,more and more users choose to transfer their applications and data into the cloud,and no longer store any data in their local memory,which can't ensure that the data stored in the cloud is still intact.How to protect the data integrity in the cloud has become a hot topic of academic research.The protocol of Provable Data Integrity(PDI)is considered to be the main method to solve this problem,which is studied in this paper.Firstly,we give a framework of provable data integrity in this paper,and analysis the unique features of data integrity under the cloud storage environment.Secondly,classification of the PDI protocol is analyzed,and on the basis of the classification,many typical PDI models are introduced and compared.Lastly,future research trends of PDI protocol for the cloud storage environment are reviewed.
