Secured Retrieval of Data with Resource Constrained Devices Using OPoR
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2016, Vol 4, Issue 4
Abstract
Cloud storage server is used to store the end user applications and their data’s in a centralized storage area but the cloud service provider itself is not trustworthy. In this paper, we are going to ensure the three main characteristics like data integrity, dynamic data operations as well as the public verifiability by using a new scheme called Proof of Retrievability (PoR). To reduce the overheads and the computational cost due to the tag generation for files at the user side, public verifiability scheme is used. To tackle all these challenges, our new scheme has introduced two servers namely cloud storage server and cloud audit server. The main task of the cloud audit server is to preprocess the data and check for integrity on behalf of the cloud users. It also eliminates the user involvement in the tag generation in preprocessing and auditing phases. In addition to that, PoR model also provides defense against the problems like spoofed reset attacks that is caused by the cloud storage server in the upload phase.
