Storing all or nothing encoded data chunks in a storage network

Abstract:

A method includes all-or-nothing (AONT) encoding a first data chunk of a plurality of data chunks in accordance with distributed data storage parameters to produce a first set of AONT encoded data pieces, where the distributed data storage parameters include a T number that corresponds to a minimum number AONT encoded data pieces needed to recover a data chunk of the plurality of data chunks, and where the first set of AONT encoded data pieces includes the T number of AONT encoded data pieces. The method further includes facilitating storage of the first set of AONT encoded data pieces in a set of storage units of the storage network, where the set of storage units includes the T number of storage units.
