Trust evaluation method in computing environment without central network

Abstract

The invention relates to a trust evaluation method used in grid computing, peer-to-peer computing, cloud computing, or other open computing environments which are oriented to China and based on the Internet and do not have central networks. The method is designed in order to promote the honest and reliable interaction of every node and has distinguishing Chinese characteristics. In view of the thinking model, the subjective desire and the way of action of Chinese people, the invention designs the trust evaluation method for network nodes so as to effectively enhance the system safety stabilityand the coordination success ratio in the computing environment without a central network in China. The trust evaluation model fully considers the identifications of the nodes, the relationship amongthe nodes, the direct interaction experiences and the objective comprehensive evaluation conditions, and also considers the dynamic changes of the node trust conditions. Due to strong pertinency, popularization capacity and feasibility, the scheme has favorable reference value and practical value.

Description

technical field [0001] The present invention is used for all kinds of open and non-centralized network computing environments (such as grid computing, peer-to-peer computing and cloud computing, etc.) based on the Internet within the scope of China, and is designed to promote honest and reliable interaction of each node A set of trust assessment methods with distinct Chinese characteristics. The technology belongs to the cross-technical application field of computer network, distributed computing and information security. Background technique [0002] With the wide application of Internet technology, a series of new open network computing (Network Computing) such as grid computing (Grid Computing), peer-to-peer computing (Peer-to-Peer Computing, P2P) and cloud computing (Cloud Computing) have emerged. Technologies, platforms, and application systems have gradually become typical network computing models, and their common characteristics are that resources on the decentraliz...

Problems solved by technology

However, in a non-central network computing environment oriented to an open environment, across organizations and management domains, nodes are dynamically dispersed and often large in scale, interacting nodes may be familiar or unfamiliar, and how to evaluate each other before transactions between unfamiliar nodes It is difficult to ensure the trustworthiness of the other party
