Abstract:
1. A method of inhibiting denial of service attacks based on consumption of processor capacity at a node in a peer-to-peer network, comprising: receiving a potentially malicious message at the node in the peer-to-peer network; wherein the potentially malicious message comprises a RESOLVE message, the RESOLVE message comprising at least one message field; examining processor capacity at the node; and rejecting processing of the potentially malicious RESOLVE message when examining the processor capacity at the node indicates that the consumption of processor capacity at the node is above a predetermined level, wherein rejecting processing of the potentially malicious RESOLVE message comprises sending an AUTHORITY message, the AUTHORITY message containing an indication that the potentially malicious RESOLVE message will not be processed because the consumption of processor capacity at the node is above the predetermined level; and accepting processing of the RESOLVE message when examining the node processor capacity indicates that the consumption of processor capacity at the node is below the predetermined level, and processing the RESOLVE message at the node.
