Simulation of Mobile Network Data Link Gateway Terminal Access Security Authentication
With the rapid development of mobile network technology,the frequency of mobile devices accessing gateway terminals is gradually increasing,and malicious access directly threatens the data chain security of gateway terminals.In order to solve the problems of poor access security authentication effect and low malicious access identi-fication rate,this paper proposes an access security authentication algorithm based on the Random Forest algorithm.This algorithm first encrypts the data chain to ensure its security.Secondly,by setting access security permission re-strictions,behavior constraints are imposed on accessing users,and the labels of the data chain are classified to deter-mine the security level of the data chain.Subsequently,the security of the server is ensured through third-party cross authentication.Finally,through the design of an algorithm based on Random forest cross authentication,targeted secu-rity authentication is adopted for data and access users of different security levels,so as to ensure the safety of the data chain.The experimental results show that the algorithm proposed in this article has improved accuracy by 6.55％ and recall by 3.27％,improving the ability to ensure data chain security.
