With the development of information technology, security issues such as 5G + Industrial Internet and Internet of Things have attracted more and more attention. This article first introduces that the Third Generation Partnership Project (3GPP) has defined a series of 5G network security technology systems, such as primary authentication, secondary authentication, GBA, AKMA etc. Secondly, this paper analyzes the security problems such as initial key leakage existing in popular security technologies in the current 5G + Industrial Internet, Internet of Things and other scenarios. Finally, in view of the security problems existing in 5G+Industrial Internet, an online password distribution method based on AKMA is designed. The method realizes the generation and online distribution of the application key, and at the same time realizes the functions of regular update and safe storage of the application key, and solves the above-mentioned security problems.
