Research On XML Document Model Based On LDAP Internet Of Things Access Control

Among the many security issues existing in the Internet of Things under the current environment,the most prominent problem is resource access control in an open business environment.In order to achieve intercommunicate between different devices and platforms,service sharing and access control mechanisms need to be more flexible.In order to realize the access and access control of data resources on the Internet of Things(IoT),this paper analyzes the drug information as the starting point,and establishes a model of drug information and an extensible markup language(XML)document node based on Lightweight Directory Access Protocol(LDAP)The security of information was studied.On this basis,the design of XML document structure and the access control of information to directory server are realized.The main contents include:(1)Firstly,we collect,sort out and summarize the related information of drugs,and describe the functional requirements of the drug information model.Based on the comparison of the existing methods of XML structure design,a conceptual model of XML drug information based on XER and AOM modeling was established.(2)With the data organization and mapping function of Power Designer graphical modeling tool,the establishment and mapping of conceptual data model to physical data model and XML model are realized.The modeling process and model diagram of AOM modeling and XER modeling are compared respectively.The XML documents conforming to the rules are obtained from the XML model.The XML document structure design is improved based on the access control requirements of the LDAP server.(3)The LDAP directory service platform based on the OpenLDAP open source directory software is set up and the mapping code between the XML node and the OpenLDAP directory entry is designed to display the XML document node information on the OpenLDAP directory server tree node.(4)According to the user access to the drug information,the control of accessing XML node information from different users is implemented on OpenLDAP,which verifies the feasibility of OpenLDAP-based Internet of Things information access control.
