当前的信任模型缺乏足够的信任评价控制机制,严重影响信任模型在网格等开放计算环境中的应用.基于传统的信任评价模型,提出信任评价控制模型.该模型采用插值技术,通过服务水平估计,有效过滤和调谐用户评价,对用户提出激励处罚机制.仿真结果表明,该模型优于现有的控制模型,能够较好地解决网格实体信任评价可靠性问题,降低恶意评价对信任评价模型的影响.
噹前的信任模型缺乏足夠的信任評價控製機製,嚴重影響信任模型在網格等開放計算環境中的應用.基于傳統的信任評價模型,提齣信任評價控製模型.該模型採用插值技術,通過服務水平估計,有效過濾和調諧用戶評價,對用戶提齣激勵處罰機製.倣真結果錶明,該模型優于現有的控製模型,能夠較好地解決網格實體信任評價可靠性問題,降低噁意評價對信任評價模型的影響.

Current trust models lack sufficient control mechanism for trust evaluation.It seriously influences the application of trust models under open computing environment such as grid.Based on traditional trust evaluation model,a trust model with evaluation control is presented,in which interpolation technique is introduced and corresponding incentive and punishment mechanism are put forward.With the estimation of service quality,the model effectively filters and tunes the user's rating.Simulation shows that the model outperforms the existing control model,and can well solve the reliable trust evaluation problem of grid entity,and can decrease the influence of malicious ratings on trust evaluation models.
