| English Abstract | When clients store large files on a remote network of unreliable distributed servers, they want to verify that their files are properly stored in the servers without any modification. This can be achieved by the techniques of data integrity. In this paper, we consider how to implement data integrity check by a third party auditor (TPA) in a distributed storage network, with the help of BLS signature. We also consider how the distributed storage network restores data when some server fails or some server crushes down. We present a data integrity check and repair (DICR) scheme, which makes use of a random (n, k) linear code for data restoration and BLS signature to implement data integrity check. Our scheme is robust in the way that the storage network can reconstruct the data when a limited number of servers fail. In the mean time, public auditing on the storage network liberates clients from computational overhead. © (2012) Trans Tech Publications, Switzerland.; When clients store large files on a remote network of unreliable distributed servers, they want to verify that their files are properly stored in the servers without any modification.
