Introduction
With the advancement of various wireless mobile network technologies, the field of Internet of Things (loT) has developed rapidly. loT is connected by multiple smart physical devices through the Internet. The loT is used in many different fields, such as smart homes, smart cities, smart health, Internet of Vehicles, and information management systems (IMS). In IMS, loT devices serve as an information collection and exchange unit. The loT device plays an important role in connecting users and systems so that they can interact. Furthermore, the IMS requires a large amount of information transmission and management. However, these loT devices send and receive highly sensitive data regarding the privacy of users or other information regarding the movement of users from one location to another location Ill. Therefore,
the primary problem is to solve the efficiency and security of identity authentication in the system. In the field of information and communication technology) the IMS needs a systematic model that contains multiple information processing units to realize. The current development of Internet and wireless network technology has brought us various convenient network services, but at the same time, it has also brought many new security threats. For example, the intrusion of the Internet system leads to information security leakages and other related incidents, which have caused various enterprises in different fields to attach great importance to the security of IMS. In an IMS, users, loT devices, computers, and servers make up the various parts of the system. These components are used to complete in formation processing operations such as access, collection, storage. and transmission of information.
