FACILITATING DATA ACCESS CONTROL IN PEER-TO-PEER OVERLAY NETWORKS

摘要

Methods and apparatuses are provided for facilitating data access controls in peer-to-peer or other similar overlay networks. A peer node storing a data object may receive a request for access to the stored data object, and may locate in the network an access control list associated with the data object using a routing mechanism included in the data object. The peer node may determine whether the requested access is authorized based on the access control list, and may grant or deny access based on the determination. A peer node storing an access control list may receive a request from a peer node storing a data object for information relating to access controls associated with the data object. The peer node storing the access control list may then send the requested information relating to the access controls associated with the data object.
