分布式信任模型在嵌入式Internet中的应用研究

为了充分利用嵌入式设备的联合处理能力,嵌入式设备之间必须进行一系列的合作.信任是人们进行社会交往的基础,人们之间的信任关系在不断地更新和传递.依据这种原理,提出了一种基于社会信任关系的协同工作分布式网络模型.嵌入式Internet系统中的设备在协作过程中,互相之间逐步形成了一种相互信任的关系,这种关系以信任表的形式存在本地端点中,并通过不断地自学习来修改信任表.给出了信任模型的建立过程以及信任参数的更新和传递算法,应用实例表明了模型的有效性.

Study of Distributed Trust Models in Embedded Internet Environments

In order to use enough united processing capacity on embedded Internet environments.A series of cooperation must be carried among embedded devices.Trust is base of social intercourse among human.The trust relation among human is updated and transferred continuously.A cooperation work and distributed network model based on society trust relationship are proposed and are used in embedded Internet system.In the embedded Internet system,when these devices cooperate,a trust relation each other is formed.The kind trust relation is restored at local peers by a trust table and modified by self-studying continuously.In this paper the structure of the trust model is given out as well as the updating and propagating algorithm of the trust value.The model has been tested and run on controlling UPS system we developed by embedded internet cooperation work,the result showed that the proposed model is not only effective,but also versatile and applicable in practical.
