Abstract
A method begins by a dispersed storage (DS) processing module encoding data to produce slices and redundancy slices and selecting primary and redundancy storage and execution units. The method continues with the DS processing module assigning partial tasks to the primary storage and execution units and generating a unique key set for each of the primary storage and execution units. The method continues with the DS processing module encrypting each of the slices with a corresponding one of the unique key sets to produce encrypted slices and sending the encrypted slices and an indication of the assigned partial tasks to the primary storage and execution units for storage and execution of the assigned partial tasks on the encrypted slices. The method continues with the DS processing module sending the redundancy slices to the set of redundancy storage and execution units for storage therein.
