摘要： A method begins with a processing module providing a data segment. The method continues with the processing module retrieving a plurality of first slices, corresponding to a previous revision of the data segment, from the distributed storage network. The method continues with the processing module recreating the previous revision of the data segment from the plurality of first slices corresponding to the previous revision of the data segment. The method continues with the processing module determining if the previous revision of the data segment compares unfavorably to the data segment. The method continues with the processing module storing the data segment in the DSN when determined that the previous version of the data segment compares unfavorably to the data segment.

摘要： A method begins by a plurality of storage units of a dispersed storage network (DSN) receiving updated properties of DSN memory. The method continues with a first storage unit and a second storage unit establishing a migration pairing and establishing a storage migration mechanism for migrating storage of data between the first and second storage units. While migrating the storage of data using the storage migration mechanism, the method continues with the first or the second storage unit receiving a data access request regarding data effected by the migrating the storage of data, determining status of the migrating storage of data, and determining which of the first and second storage units is to process the data access request based on the status to produce a determined storage unit. The method continues with the determined storage unit processing the data access request.

摘要： A method begins by a first device generating a self-validating message by creating a master key, using the master key to create a message encryption key, encrypting a message using the message encryption key to produce an encrypted message, encrypting the master key using a public key of a second device to produce an encrypted master key, and including a message authentication code of the first device in the self-validating message. The method continues by the second device receiving and decoding the self-validating message by verifying the message authentication code of the first device, and when the message authentication code of the first device is verified, decrypting the encrypted master key using a private key of the second device to recover the master key, using the master key to create the message encryption key, and decrypting the encrypted message using the message encryption key to recover the message.

摘要： A method begins by a processing module of a dispersed storage network (DSN) ascertaining a decode threshold value for dispersed storage error encoding data for storage in storage units of the DSN. The method continues with the processing module determining a total width value for the dispersed storage error encoding based on the decode threshold value, a number of selected sites within the DSN, and a number of selected storage units of the selected sites. The method continues with the processing module determining logical storage slots within the selected storage units based on the total width value, the number of selected, and the number of selected storage units. The method continues with the processing module writing a set of encoded data slices to a total width value of the logical storage slots within at least some of the selected storage units of the selected sites based on a slice-to-slot mapping.
