The Research and Simulation of 5G Network Anti Attack Agorithm Based On Polling Encryption Authentication Mechanism

为解决5G网络抗攻击领域内存在的网络抖动难以抑制、恶意攻击熔断效率不高等不足,提出了一种基于轮询加密鉴权机制的5G网络抗攻击算法.首先,利用基站和节点间存在的拓扑聚类关系,采用拓扑距离切割来实现对节点加入过程的主动应答,按能量水平实现快速排序,以增加恶意攻击节点的运行成本,优化网络传输质量;随后,基于拓扑距离、能耗等多参数,设计了一种基于多参数筛除机制的区域稳定方法,能够通过基准鉴权时钟优先清除不同步的恶意节点,以提升网络对恶意节点的熔断效果;最后,按照最小生成树来形成传输区域,有效降低流量激增对网络带来的恶意攻击,优化区域间传输,以提高网络抖动抑制能力.仿真实验表明,所提算法具有更强的网络抖动抑制能力及更优的恶意攻击熔断效果.

In order to solve the problems of difficult suppression of network jitter and low efficiency of malicious attacks in the field of 5G network anti attack,a 5G network anti attack algorithm based on polling encryption authentication mechanism is proposed.Firstly,the algorithm makes use of the topological clustering relationship between the base station and the nodes,adopts the topological distance cutting method to realize the active response to the node joining process,and realizes rapid sorting according to the energy level,so as to increase the operation cost of malicious attack nodes and optimize the network transmission quality.Then,based on multi parameters such as topological distance and energy consumption,a regional stability method based on multi parameter screening mechanism is designed,which can preferentially remove asynchronous malicious nodes through the reference authentication clock,so as to improve the fusing effect of the network on malicious nodes.Finally,the transmission area is formed according to the minimum spanning tree to further reduce the malicious attack on the network caused by the surge of traffic,and optimize the inter area transmission to improve the ability of network jitter suppression.Simulation results show that the proposed algorithm has stronger network jitter suppression ability and better malicious attack effect.
