The Research on Identity Authentication Scheme of Internet of Things Equipment in 5G Network Environment

As the representative of the third industrial revolution, the Internet of Things technology has become a huge driving force behind the changes in human production and lifestyle after the Internet. With its unique features and advantages, IoT technology has extensive and in-depth applications in smart cities, intelligent transportation, and industrial production. With the rapid development of 5G networks, the characteristics of 5G networks with fast speed, low latency, and large access volume will provide a broader platform for the development of Internet of Things technology. At the same time, the arrival of the 5G era will bring great challenges to the security of the Internet of Things. As the entrance and business cornerstone of the IoT network, identity authentication will play an important role in responding to IoT security threats. At present, the efficient and reliable IoT identity authentication method has been the subject of constant exploration and research in the academic world, especially the Internet of Things identity authentication method in the 5G network environment. This paper first analyzes the development and existing problems of 5G technology and Internet of Things technology. On this basis, it summarizes the theoretical basis, technical approach, and advantages and disadvantages of current identity authentication. Finally, this paper discusses the application of blockchain technology to 5G. A new trend in the development of the Internet of Things identity authentication in the network environment.
