Access control in a dispersed storage network

摘要

A method begins dispersed storage error encoding data in accordance with dispersed storage error encoding parameters to produce a plurality of set of encoded data slices. The method continues by determining access control information for the plurality of sets of encoded data slices. The method continues by determining whether one or more encoded data slices of the plurality of sets of encoded data slices has individual access control information. The method continues when the one or more encoded data slices has individual access control information by creating a plurality of sets of appended slices, which is done by appending corresponding individual access control information to each of the one or more encoded data slices and appending a representation of the access control information to remaining encoded data slices of the plurality of sets of encoded data slices. The method continues by outputting the appended slices.
