Method, apparatus, system, customer node, peer node and convergent point for preventing node forged identity

Abstract

The embodiment of the invention discloses a method, a device, a system, a client node, a peer node and a convergent node, which are used for preventing identity fakery by node in a peer-to-peer network, and the embodiment of the invention relates to the field of overlay networks and solves the problems of large consumption and long time delay. The method adopted by the embodiment of the invention comprises the following steps: after the client node finds the service peer node, identity of at least one side of the client node or the peer node is authenticated; and after the authentication is passed, the client node or the peer node establishes an anti-fake identity table for the other side. The device adopted by the embodiment of the invention comprises an authenticating unit which is used for checking identity validity, a storage unit which is used for establishing and storing the anti-fake identity table, and an identifying unit which is used for identifying malicious nodes. The client node, the peer node or the convergent node respectively comprises an authenticating unit, a storage unit and an identifying unit. The system adopted by the embodiment of the invention comprises the peer node and the client node. The invention can be widely applied to the identity authentication of equipments in the peer-to-peer network.

Description

technical field [0001] The invention relates to the field of overlay networks, in particular to a method, device, system, client node, peer node and convergence point for preventing network equipment from forging identities. Background technique [0002] Overlay Network (Overlay Network) is a virtual network established on top of one or more existing lower-layer networks (such as: physical network or logical network), which can realize some specific functions that are difficult to achieve on the lower-layer network, such as: message Routing or topology maintenance, etc. [0003] P2P (Peer to Peer) overlay network, that is, a peer-to-peer network, is an overlay network established on the basis of the existing Internet using the P2P model. The peer-to-peer network can be based on the existing Internet (for example: client node / server type network), realize the equal status between peer nodes (Peer) in the peer-to-peer network, and the resources between peer nodes Sharing and...
