    摘要: A method begins by a processing module identifying an encoded data slice to be rebuilt, selecting a decode threshold number of dispersed storage (DS) units of a storage set of DS units, generating a decode threshold number of key pairs, wherein a key pair of the decode threshold number of key pairs corresponds to a DS unit of the decode threshold number of DS units, and sending partial rebuilding requests to the decode threshold number of DS units, wherein a partial rebuilding request of the partial rebuilding requests includes the key pair. The method continues with the processing module receiving encrypted partial encoded data slices, wherein an encrypted partial encoded data slice received from the corresponding DS unit includes a multiple encryption, using the key pair, of a partial encoded data slice and decoding the encrypted partial encoded data slices to rebuild the encoded data slice.

    摘要: A method for data transfer from a first computing device to a second computing device begins when the first computing device is paired with a transfer token module by the first computing device sending the data to the transfer token module. The method continues with the transfer token module encoding the data utilizing a dispersed storage error encoding function to produce a set of encoded data slices and sending the set of encoded data slices to a target destination. The method continues, when the second computing device is paired with the transfer token module, with the transfer token module retrieving the set of encoded data slices from the target destination and decoding the set of encoded data slices utilizing the dispersed storage error encoding function to recapture the data. The method continues with the second computing device storing the data.

    摘要: A method begins with a computing device receiving a request to acquire digital content from a digital content provider and forwarding the request to a dispersed storage network (DSN) pre-paid module. The method continues with the DSN pre-paid module validating the request, generating a plurality of sets of at least a threshold number of digital content read requests, and sending the plurality of sets of the at least a threshold number of digital content read requests to the digital content provider via the computing device when the request to acquire the digital content is validated. The method continues with at least one of the DSN pre-paid module and the computing device receiving a plurality of sets of at least a decoded threshold number of encoded data slices and decoding the plurality of sets of the at least a decoded threshold number of encoded data slices to produce the digital content.

    摘要: A method begins by a processing module generating a payload section of a dispersed storage network (DSN) frame regarding a check request operation by generating one or more slice name fields of the payload section to include one or more slice names corresponding to one or more encoded data slices and generating a transaction number field of the payload section to include a transaction number corresponding to the check request operation. The method continues with the processing module generating a protocol header of the DSN frame by generating a payload length field of the protocol header to include a payload length that represents a length of the payload section and generating remaining fields of the protocol header.
