Methods and apparatus for reducing the effectiveness of chosen location attacks in a peer-to-peer overlay network

摘要

Methods and apparatus for reducing the effectiveness of chosen location attacks in a peer-to-peer overlay network. A method includes determining that new node identifiers are to be generated for a plurality of nodes in the network, inputting parameters to a hash function to generate a selected node identifier, and adopting a location in the network associated with the selected node identifier. Another method includes receiving a node identifier associated with a selected node, inputting parameters associated with the selected node to a hash function to generate a corresponding node identifier, comparing the node identifier with the corresponding node identifier, and determining that the selected node is a potential attacker if the node identifiers do not match. Another method includes detecting responsibility for initiating an update to one or more node identifiers, generating parameters to generate the node identifiers, and transmitting the parameters on the network.
