摘要
本文将证书敏感度和实体声誉相结合,提出基于可信敏感度的信任协商策略来避免敏感信息的披露;引入协商第三方来解决循环依赖策略,提高服务成功率.最后分析了策略的计算和通信开销,在NUPT网格平台的测试结果证实了该策略性能令人满意.
The paper proposes a masted sensitivity improved negotiation strategy, which is orthogonal to credentials' sensitivity and entity' s reputation. Such modifications help prevent inadvertent disclosure of sensitive information. We also introduce negotiation third parties to solve cyclic dependent policies, which effectively promote the response ratio of grid services request. Its practical performance was validated on NUPT-glid platform, and the results are satisfactory.
