1. A method for execution by a computing device in a dispersed storage network (DSN), the method comprising:

  • executing by at least one processor of the computing device the steps of;

    determining a slice name corresponding to a rebuilt slice that corresponds to a set of encoded data slices (EDSs) that is generated based on a data object that is segmented into a plurality of data segments, wherein a data segment of the plurality of data segments is dispersed error encoded in accordance with dispersed error encoding parameters to produce the set of EDSs;

    determining a storage unit for storing the rebuilt slice in the DSN;

    reconstructing the rebuilt slice based on other EDSs of the set of EDSs in accordance with the dispersed error encoding parameters;

    sending, via an interface circuitry of the computing device and via the DSN, an authentication request to the storage unit that includes a request to store the rebuilt slice in the storage unit;

    receiving, via the interface circuitry of the computing device and via the DSN, receiving an authentication response; and

    sending, via the interface circuitry of the computing device and via the DSN, the rebuilt slice to the storage unit to be stored therein, when the authentication response indicates that the authentication request is authenticated.
