Calculation method for entity node reliability under grid environment

Abstract

Sharing and collaboration under a grid environment break through the restrictions of a management domain; and the grid technology is adopted to connect various cross-domain resources which are broadly distributed. The invention demonstrates and explains the superposition credibility of strategy spaces, and connects the strategy spaces together through strategy conversion based on characters to become a collaborative union definition, so as to provide foundations for resource sharing and also provide flexible collaboration solving capacity. According to the definition, an uncertain reasoning method is used to respectively give out credibility characteristic vector calculations comprising three characteristic values, and then a credibility assessment and calculation method for strategy conversion based on characters is disclosed. The calculation method for entity node reliability under network environment solves the problems that any information of other nodes and sensitive subtotaling results cannot be obtained by any node when a plurality of nodes collaborate to calculate under a mutually-trustless distributed environment, and establishes the reliability and predictability of mutual trust relationship under the grid environment.

Description

technical field [0001] The invention relates to the field of context-aware computing, in particular to a method for realizing credibility computing of roles spanning different organizations. Background technique [0002] In the traditional closed environment and the distributed environment of small-scale sharing and collaboration, due to the relative familiarity of user groups, the relatively limited and controllable number of entities, mutual trust issues are limited to within the organization, and the trust system is often established based on roles. is also more covert. However, context-aware computing is a cross-domain complex system, and resource sharing and access has expanded from a closed, centralized management, and relatively static intra-domain environment to an open, decentralized, autonomous, and dynamic collaborative inter-domain computing environment. [0003] In context-aware computing environment, trust itself has many uncertainties. Due to the lack of a p...

Problems solved by technology

[0004] In view of the defects in the above-mentioned prior art, the purpose of the present invention is to propose a calculation method for the credibility of entity nodes in a grid environment, which solves the problem of realizing a plurality of nodes cooperatively calculating in a distributed environment that does not trust each other. No node can obtain other nodes' trust information and sensitive intermediate calculation results
