A dynamic mobile p2p trust management model system and method

Abstract

The invention discloses a dynamic mobile P2P trust management model system. According to the dynamic mobile P2P trust management model system, every node is composed of a local trust value computing and storing module, an indirect reputation value measuring module and a transaction management module, wherein local trust value computing and storing module computes the integral trust value of the node by comprehending the historic transaction information of the node, stores the transaction information and the trust value of nodes having transaction with the node and transmits the trust value of the nodes to the transaction management module; the indirect reputation value measuring module collects the trust value fed back by neighboring nodes, performs effectiveness verification on the feedback trust value, eliminates untrusted feedback value, selectively collects the reputation value of the nodes computed posteriorly, and transmits the reputation value of the computed nodes to the transaction management module; the transaction management module selects nodes according to the reputation value or the trust value of the nodes, executes a transaction and transmits and stores the information of the nodes in the transaction to a trust value computing and storing module.

Description

technical field [0001] The invention relates to a dynamic mobile P2P trust management model system and method, and belongs to the technical field of wireless network communication. Background technique [0002] The successful application of peer-to-peer network (abbreviation: P2P) makes many researchers pay attention to the field of mobile computing. Moreover, as the storage and computing capabilities of intelligent mobile terminals continue to increase, and the battery capacity continues to expand, online P2P applications such as resource sharing and social networking are extended to the wireless field, and there are more and more broad prospects. [0003] However, the mobility, anonymity, limited resources of nodes in the mobile P2P network, and the dynamic joining and leaving of nodes cause a series of unsafe factors in the network, such as: unreliable service quality, malicious nodes may provide virus files, false files , selfish nodes may not participate in the interac...
