移动网络数据链网关终端访问安全性认证仿真

Simulation of Mobile Network Data Link Gateway Terminal Access Security Authentication

随着移动网络技术的快速发展,移动设备访问网关终端的频次也逐渐提高,而恶意访问则直接威胁着网关终端的数据链安全。为了解决当前访问安全性认证效果差、恶意访问识别率低等问题,提出了一种基于随机森林算法的访问安全性认证算法。算法首先对数据链进行加密,从而保障数据链的安全;其次通过设置访问安全权限限制,对访问用户进行行为约束,并对数据链的标签进行分类,从而确定数据链的安全级别;随后通过第三方交叉认证的方式保障了服务器的安全;最后通过设计基于随机森林交叉认证的算法,对不同安全级别的数据及访问用户采取针对性的安全性认证,从而达到保障数据链安全的效果。实验结果表明,所提算法在准确率上提升了6.55%,在召回率上提升了3.27%,提高了保障数据链安全的能力。

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 identification 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 restrictions,behavior constraints are imposed on accessing users,and the labels of the data chain are classified to determine 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 security 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.
