Many storage systems rely on replication to increase
the availability and durability of data on untrusted stor-
age systems. At present, such storage systems provide no
strong evidence that multiple copies of the data are actu-
ally stored. Storage servers can collude to make it look
like they are storing many copies of the data, whereas in
reality they only store a single copy. We address this short-
coming through multiple-replica provable data possession
(MR-PDP): A provably-secure scheme that allows a client
that stores t replicas of a file in a storage system to verify
