摘要:
A method begins by a dispersed storage (DS) processing module receiving a request to retrieve a data object based on a search attribute. The method continues with the DS processing module retrieving and decoding a set of encoded index data slices to reconstruct an index file. The method continues with the DS processing module identifying a child index file, retrieving and decoding a set of encoded child index data slices to reconstruct the child index file, and determining whether the child index file includes a dispersed storage network (DSN) address for the data object. When the child index file includes the DSN address for the data object, the method continues with the DS processing module retrieving a plurality of sets of encoded data slices based on the DSN address and decoding the plurality of sets of encoded data slices to recapture the data object.

A method begins by a dispersed storage (DS) processing module receiving a request to copy a data object in a dispersed storage network (DSN). The method continues with the DS processing module identifying one or more sets of at least a decode threshold number of slice names for one or more sets of encoded data slices of the data object and generating one or more sets of at least a decode threshold of new slice names. The method continues with the DS processing module sending the one or more sets of at least a decode threshold of new slice names to storage nodes of the DSN and instructing the storage nodes to link the one or more sets of at least a decode threshold of new slice names to the one or more sets of encoded data slices thereby producing a non-replicated copy of the data object.

A method begins by a dispersed storage (DS) processing module generating a temporary public-private key pair, a restricted use certificate, and a temporary password for a device. The method continues with the DS processing encoding a temporary private key to produce a set of encoded private key shares and encoding the restricted use certificate to produce a set of encoded certificate shares. The method continues with the DS processing module outputting the set of encoded private key shares and the set of encoded certificate shares to a set of authentication units. The method continues with the DS processing module outputting the temporary password to the device such that, when the device retrieves the set of encoded private key shares and the set of encoded certificate shares, the device is able to recapture the temporary private key and the restricted use certificate for accessing a dispersed storage network (DSN).
摘要:
A method begins by a requesting entity sending a distributed storage network (DSN) access request to a request verification entity, wherein the DSN access request includes a signed certificate and DSN accessing information. The method continues by a request verification entity sending a signed DSN access request to the requesting entity when the request verification entity signs the DSN access request after verifying the signed certificate and the DSN accessing information. The method continues by the requesting entity sending the signed DSN access request to a DSN accessing entity. The method continues by the DSN accessing entity sending an authorized DSN access request to the DSN via a network connection when the DSN accessing entity verifies a signature of the request verification entity, wherein the authorized DSN access request includes, at a minimum, the DSN accessing information.

A method begins by a processing module generating a deterministic key from data and encrypting the data using the deterministic key to produce encrypted data. The method continues with the processing module generating transformed data from the encrypted data and generating a masked key from the deterministic key and the transformed data. The method continues with the processing module combining the masked key and the encrypted data to produce a secure package.

A method operating on a computer begins by generating a read command to read at least some of a plurality of data slices from a dispersed storage network. The method continues by receiving the at least some of the plurality of data slices. The method continues by performing a reverse information dispersal algorithm on at least some of the plurality of data slices to produce a plurality of transposed data elements. The method continues by reverse transposing the plurality of transposed data elements to recover data elements of a data segment.

A method begins by a processing module determining that a data storage request is a cloud data storage request. The method continues with the processing module determining at least one of a cloud storage access reliability indication and a cloud storage data reliability indication for the data storage request. The method continues with the processing module sending the data storage request and the at least one of cloud storage access reliability indication and cloud storage data reliability indication to a cloud storage system.

A method begins by a processing module receiving a first request to store a program. The method continues with the processing module determining first error coding dispersal storage function parameters and encoding a data segment of the program. The method continues with the processing module determining whether a second request to store the program is received. The method continues with the processing module encoding a second data segment of the program in accordance with the first error coding dispersal storage function parameters when the second request is not received. The method continues with the processing module changing the first error coding dispersal storage function parameters based on the another request to produce second error coding dispersal storage function parameters when the second request is received. The method continues with the processing module encoding the second data segment in accordance with the second error coding dispersal storage function parameters.

A method begins by a dispersed storage (DS) processing module generating a shared secret key from a public key of another entity and a private key using a first modulo prime polynomial function, wherein a public key is generated from the private key using a second modulo prime polynomial function and wherein the public key of the other entity is derived using the second modulo prime polynomial function on a private key of the other entity. The method continues with the DS module encrypting a message using the shared secret key to produce an encrypted message. The method continues with the DS module outputting the encrypted message to the other entity.
