IoT security access gateway authentication design

There are many security risks in the data exchange of the Internet of Things. Therefore, this paper effectively integrates various technologies to design IoT security access gateway authentication to ensure the secure operation of IoT. The IoT gateway authentication hardware is divided into data collection, processing, access and power supply management modules to improve the security of IoT authentication and the efficiency of data processing. In the software design, the terminal device access identity authentication is realized through the communication protocol, and the identity authentication technology is analyzed to strengthen the security awareness of the network nodes. Test experiments show that in the face of different network problems, it can play a role in ensuring network security access and achieve more convenient, smarter, and more autonomous management.
