Abstract
A method begins by a processing module receiving a data storage request that includes data and determining dispersed storage error encoding parameters for dispersed error encoding storage of data. The method continues with the processing module dispersed storage error encoding the data in accordance with the dispersed storage error encoding parameters to produce a set of encoded data slices and establishing access control information for each encoded data slice of the set encoded data slices in accordance with the dispersed storage error encoding parameters to produce a set of access control information. The method continues with the processing module appending a corresponding one of the set of access control information to each of the set of encoded data slices to produce a set of appended slices and outputting the set of appended slices to a set of dispersed storage units.
