Point-to-point network prestige management method based on market model

A point-to-point network and management method technology, applied in the field of point-to-point network management, can solve problems such as feedback information interfering with the normal operation of the system, lack of effective constraints on participants, and inability to guarantee the authenticity of node feedback, so as to resist harm and restrain rational users The effect of the underlying motivation for cheating

Embodiment Construction

[0026] The invention aims at the peer-to-peer network for the purpose of resource sharing, and manages the reputation of network node users based on the DHT P2P routing protocol. Let the number of n participants in the system be set P={P 1 , P 2 ,...P n}, each node has a unique node identifier, and is automatically assigned a supervisor by the system. The supervisor is responsible for recording, storing and maintaining the reputation information of the corresponding node. In the DHT-based peer-to-peer network, for any node P i , can use s globally known hash functions on the node identifier to map to s nodes to form a supervisor set S(P i ), considering that the nodes in the peer-to-peer network may leave the system at any time, resulting in network fluctuations, if some nodes do not exist in the network, they will be replaced by their successor nodes. ,

[0027] When two nodes trade, the responsibility of the seller is to provide resources and services that meet the agree...

Abstract

The invention relates to a point-to-point network reputation management method based on a market model. On the base of the P2P routing protocol based on DHT, both buyer and seller and a third party supervisor together manage note reputation. Compared with the prior art, the method has the advantages that: a resources service level obtained by a node is directly related to contribution of the node for a system; users cannot seek profit for selves via unreal feedback information, so as to effectively inhibit the rigged potential motive of the rational users; and damage caused by various attacks of hostile nodes can be resisted. In the assist of the method, the resources service level obtained by the node is directly related to the contribution of the node for the system; the users cannot seek profit for selves via the unreal feedback information, so as to effectively inhibit the rigged potential motive of the rational users; and the damage caused by various attacks of the hostile nodes can be resisted.

Description

technical field [0001] The invention relates to a point-to-point network management method, specifically a market model-based point-to-point network reputation management method, aimed at a peer-to-peer network for resource sharing, and based on a DHT-based P2P routing protocol, to manage the reputation of network node users. Background technique [0002] The openness of the system in the peer-to-peer network enables it to more effectively utilize the idle resources of the edge computers on the Internet. The freedom of the nodes discovers potential users in the Internet. The main body participating in the system is a large number of free-flowing users. However, the openness of the system and the freedom of nodes make the peer-to-peer network lack of effective constraints on the participants, making it difficult to control the selfish behavior of the rational nodes that account for the main body of the network, and it is difficult to eradicate malicious behaviors targeting the...
