  • Publication number: 20230388101
    Abstract: A method for execution in a storage network begins by performing a key derivation function on a password to produce a key and issuing a set of passwords based on the key to a set of storage units, where a data object is dispersed error encoded in accordance with dispersed error encoding parameters to produce a set of encoded data slices and the set of encoded data slices are stored in the set of storage units. The method continues, by receiving at least a decode threshold number of confidential information responses from the set of storage units and regenerating a set of keys for the confidential information responses. The method then continues by decrypting the confidential information responses using the set of keys to reproduce a set of encoded data slices and dispersed storage error decoding a decode threshold number of the set of encoded data slices to produce recovered data.

  • Publication number: 20230214303
    Abstract: A method for execution by a distributed storage network begins by receiving a request to transfer a copy of a set of encoded data slices from at least some associated virtual storage vaults to a destination virtual storage vault and continues by determining whether the destination storage unit supports a source virtual storage vault of the at least some source virtual storage vaults. When the destination storage unit supports the source virtual storage vault the method continues by determining a sub-set of encoded data slices of the set of encoded data slices for transfer and finally, by facilitating sending the sub-set of encoded data slices to the destination storage unit.

  • Patent number: 11604587
    Abstract: A computing device includes an interface configured to interface and communicate with a dispersed storage network (DSN), a memory that stores operational instructions, and a processing module operably coupled to the interface and memory such that the processing module, when operable within the computing device based on the operational instructions, is configured to perform various operations. The computing device receives, from another computing device, a vault provisioning request and processes the vault provisioning request to determine whether the other computing device is authorized to request provisioning of another vault within the DSN. When the other computing device is authorized, the computing device generates a vault within the DSN in response to the vault provisioning request from the other computing device and updates access control information within the DSN to include an initial access control for the vault and an identifier of the other computing device.
