NETWORK NODES AND METHODS FOR DATA AUTHORIZATION IN DISTRIBUTED STORAGE NETWORKS

摘要

Storage authorization and access control of data stored on a peer-to-peer overlay network is provided. A publishing node (502) stores data on a storage node (506) in the overlay network. The publishing node (502) is adapted to facilitate data storage authorization by generating a resource identifier (516) as a function of a usage string associated with a data type"" to be stored. A storage request (504) is generated that includes the resource identifier (516) and data to be stored (518). The storage request may be sent to the storage node (506). The storage device (506) receives the storage request (504) sent by a publishing node (502), including a resource identifier (516) and data to be stored (518). Independent storage authorization is performed by the storage node (506) at an overlay level by verifying (510, 512) the resource identifier. The data in the storage request is stored at the storage node if the resource identifier is successfully verified.
