The Study On Attribute-based Internet Of Things Of Public Environment Access Control Strategy

With the rapid development of information technology and the Internet,the information age has entered a new phase,and the Internet of Things is expanding on the Internet.The application prospects of the Internet of Things have received great attention from various countries and academia.Because of the dynamic,real-time,and multi-attribute characteristics of network data,higher requirements are placed on the security of data transmission,storage,and access.The authentication security issues and fine-grained access control in the sharing of information resources in the public environment Internet of Things have become an important research topic.However,there are no well-established standards and solutions at home and abroad.This article mainly focuses on access security in the process of data sharing in the Internet of Things,and gives an attribute-based access control scheme.In this scheme,this paper presents a user attribute authenticatio n method.The public environment of the Internet of Things is an open IoT network environment with multiple users.The data resources of multiple users are stored in the same environment.In this environment,the access controllability of user upload data information is particularly important.This paper presents an attribute-based access control scheme for the security of data information in the Internet of Things in the public environment.In this scheme,a user attribute authentication method is proposed to ensure that the user performs attributes-based access control.It is reliable.Attribute-based access control strategy is studied,attribute-based access control model,access control rules and policy formulation are introduced.The formal definition and framework of the model are introduced.Through the attribute-based access control scheme,authorized users can access authorized resources in their rights,rejecting illegal users and achieving flexible and fine-grained access control.Applying the authentication and authorization-based access control scheme to the drug information internet of things,and testing the attribute-based access control,the result shows that the scheme can ensure the confidentiality and integrity of the drug information data.Experiments have proved the effectiveness of the scheme.
