Research On Inter-domain Trust Model Based On Gateway Of Internet Of Things

With development of the wireless communication technology, perceptionidentification technology, more and more researchers began to focus oncommunication and exchange of information between goods and products of theobjective world, the concept of the internet of things also have been presented.Internet of Things integrating of the existed Internet, mobile communication network,wireless sensor network and other network, from the customer’s needs, are widelyused in the exchange of information between persons and things, things and things, toprovide information services and applications covering all aspects of life, setting off athird wave of the world’s information industry development.Currently, the Internet of Things technology is in rapid development stage, andgradually formed a large-scale, heterogeneous, dynamic, distributed networkingenvironments. How to across the single trust domain restriction, achieve informationexchange and resource sharing among multiple trust domains is very important for theentities in the Internet of Things environment. However, the research on cross-domaintrust issue in the IOT networking environment is still in its infancy, has made someresearch, but there are still some problems to be solved.This paper focuses on the cross-domain trust issues between entities in the IOTnetworking environment, references pervasive network, P2P network trust model,puts the gateway technology into IOT trust model research work, proposes a new IOTinter-domain trust model which implements trust value conversion among domains bygateway. This paper describes the basic structure and operating principle of GB-UTMmodel, and designs cross-domain nodes history scheduling record table structure. Inthis model, the history scheduling record was stored on gateway by the strongcomputing and storage capacity. With the trust factor, history factor and context, thenode trust value has been computing, and gives a detailed calculation formula for thecross-domain node trust. Finally, proposes the main algorithm of node cross-domaintrust, and gives a detailed workflow of the GB-UTM trust management model.The experiments show that the model is efficient on SSP when IOT full load andstabilization, reduced the passive affect of veracity inter-domain trust value.
