物联网环境下的跨域信任评价研究

A Cross-Domain Trust Evaluating Under the Environment of Internet of Things

安全是物联网发展的基础,信任建模和管理是提高安全的手段之一,信任是以域为单位进行管理和评价的,但是在实际网络中,经常发生域内找不到合适资源时,进行跨异构域调度.本文针对上述问题,提出一个跨域信任评价的二级分层模型,以解决不同域间的信任评价与转换,实现节点跨域调度.

Security is the basis for the development of the internet of things while trust modeling and management are one of the means of security promotion. Trust is the managed and evaluated by the unit of the domain. But in actual network, cross domain scheduling often happens when suitable resources can be found in the field. For the above problems, this paper puts forward the structure of cross-domain trust evaluation system by taking static and dynamic attributes as intra-domain and cross-domain trust evaluation index; it introduces the two-level hierarchical evaluation model to solve the problems of intradomain evaluation through comprehensive evaluation ; it realizes the transformation between cross-domain random nodes through the transformation and comparison in application of normal distribution parameters, completing the cross-domain trust evaluation.
