Research And Application Of Cross-Platform Resource Interaction Method In Internet Of Things Environment

With the rapid development of the Internet of Things,the industries have formed a closed and powerful platform system in their respective ones.The data format,communication protocol,semantic description and architecture of these platforms are different,so the resource interflow among heterogeneous platforms has become a big problem.At present,some methods for resolving resource interconnection of heterogeneous Internet of Things platforms have problems of poor scalability and low efficiency,and the security authentication mechanism between platforms is complicated,and it is easy to leak user privacy data.In view of these problems,this paper studies the resource interaction method and authentication mechanism of IoT heterogeneous platform,and constructs the prototype system to complete the interaction of resources among three heterogeneous platforms,and verifies the feasibility of the method.The main contents of this paper are as follows:(1)In view of the problem that the current heterogeneous Internet of Things platform resource interaction method is not scalable and inefficient,this paper proposes a loosely coupled resource interaction method,and defines a series of interface specifications,with the market components and adapter development kit can complete the resource interaction between heterogeneous platforms,and finally verify the feasibility of the method through the prototype system.(2)Research on the problem of complexity in process,inefficient,and easy to disclose the user's private data existing in end-to-end authentication mechanism,this paper proposes a The authentication mechanism combined with OAuth and Token which can not only reduce the steps of traditional authentication,but also don't need to disclose user's private data in the authentication process,thereby improving security and authentication efficiency.In addition,this paper puts forward corresponding effective improvement measures for common replay attacks and man-in-the-middle attacks,namely,preventing replay attacks by adding time stamps and random Numbers,and preventing man-in-the-middle attacks by adding public-private key encryption.(3)The proposed resource interaction method is verified by building a prototype system,which contains three heterogeneous iot platforms,namely oneM2 M,Restful and webservice.A resource is set in each platform to complete the resource interaction with the adapter.
