Abstract: When an access metric regarding an encoded data object exceeds an access threshold, a method begins by a processing module of a dispersed storage network (DSN) retrieving encoded data slices of a first plurality of sets of encoded data slices and recovering the data object utilizing first dispersed storage error encoding parameters. The method continues with the processing module re-encoding the recovered data object using second dispersed storage error encoding parameters to produce a re-encoded data object, where the re-encoded data object includes a second plurality of sets of encoded data slices. The method continues with the processing module outputting the second plurality of sets of encoded data slices to storage units of the DSN for storage therein and sending a message to retrieving devices of the DSN, where the message indicates use of the second plurality of sets of encoded data slices for the data object.

Abstract: A method begins by a processing module storing a set of encoded data slices in storage units. A data segment of data is encoded, in accordance with dispersed storage error encoding parameters, to produce the set of encoded data slices. The dispersed storage error encoding parameters include a decode threshold number and a pillar width number, which is at least twice the decode threshold number. The method continues with the processing module processing a first request for retrieval of the data segment by retrieving a first sub-set of encoded data slices, which includes the decode threshold number, and decoding them to produce a first recovered data segment. The method continues with the processing module processing a second request for retrieval of the data segment by retrieving a second sub-set of encoded data slices, which includes the decode threshold number, and decoding them to produce a second recovered data segment.

Abstract: A method begins by a source processing module securing data based on a key stream to produce secured data, where the key stream is derived from a unilateral encryption key accessible only to the source processing module, and sending the secure data to an intermediator processing module, where desecuring the secured data is divided into two partial desecuring stages. The method continues with the intermediator processing module partially desecuring the secure data in accordance with a first partial desecuring stage to produce partially desecured data and sending the partially desecured data to a destination processing module. The method continues with the destination processing module further partially desecuring the partially desecured data in accordance with a second desecuring stage to recover the data, where the destination processing module does not have access to the encryption key or to the key stream.

Abstract: A method begins by a by a first device of a dispersed storage network (DSN) sending a set of write revision requests to storage units of the DSN. The method continues with one of the storage units generating a write revision response regarding a potential write conflict issue. The method continues with the first device receiving the write revision responses to produce a set of received write revision responses and interpreting the set of received write revision responses to determine whether a write conflict issue exists. When the write conflict issue exists, the method continues with the first device issuing a set of write roll back requests to the storage units. When the write conflict issue does not exist, the method continues with the first device issuing a set of next phase write requests to the storage units regarding storing revised encoded data slices.
