    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 dispersed storage device within a dispersed storage network includes a processing module for determining whether to add a new generation for a vault, in which the vault identifies at least one user having data to be stored. When the new generation is to be added to the vault, the processing module further assigns a vault generation identifier to the new generation and reserves memory for the new generation.

    摘要: A distributed storage integrity system in a dispersed storage network includes a scanning agent and a control unit. The scanning agent identifies an encoded data slice that requires rebuilding, wherein the encoded data slice is one of a plurality of encoded data slices generated from a data segment using an error encoding dispersal function. The control unit retrieves at least a number T of encoded data slices needed to reconstruct the data segment based on the error encoding dispersal function. The control unit is operable to reconstruct the data segment from at least the number T of the encoded data slices and generate a rebuilt encoded data slice from the reconstructed data segment. The scanning agent is located in a storage unit and the control unit is located in the storage unit or in a storage integrity processing unit, a dispersed storage processing unit or a dispersed storage managing unit.

    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.
