A method includes encoding data via erasure coding to produce a plurality of data slices. The method further includes determining a plurality of identifiers corresponding to the data. The method further includes generating integrity information based on the plurality of identifiers by performing a cyclic redundancy check. The method further includes storing the plurality of data slices, the plurality of identifiers, and the integrity information in a storage system.
