Abstract
Methods for use in a dispersed storage network (DSN) to encode data using threshold based secret sharing schemes. In one embodiment, a computing device uses a first threshold based secret sharing scheme in accordance with first secret sharing parameters to encode a data segment of a data file to produce a set of encoded data shares. The computing device then sends the set of encoded data shares to a set of storage units, including sending an encoded data share to a first storage unit of the set of storage units. Upon receiving the encoded data share, the first storage unit encodes the encoded data share using a second threshold based secret sharing scheme in accordance with second secret sharing parameters to produce a set of encoded data sub-shares. The first storage unit then stores the set of encoded data sub-shares in a set of memory devices of the storage unit.
