摘　　要：通信网络信号传输时,会有一定几率受到恶意攻击,降低网络安全性能。为此,在5G环境下提出一种网络独立通信层信号安全检测方法。采用控制转发分离和控制功能重构技术,重构5G环境体系框架,加强独立通信网络的整体性能;通过多尺度小波包分析法,获得网络分布式隐藏异常流量检测原理,分析网络通信入侵干扰信号,通过EMD分解信号信息确定网络通信入侵干扰信号阈值;引入傅立叶变换的分数幂形式,用高阶累积量切片因子抑制网络数据链路层信号噪声,并利用敏感数据检测法,获得网络攻击信号,有效识别网络的恶意攻击行为,确保网络独立通信层信号安全性。实验结果表明:上述检测方法可以有效改善网络通信过程中的恶意攻击现象,使通信信息传输更加安全。During the network signal transmission,there will be some malicious attacks,reducing the network security.Therefore,a method to detect signal security of network-independent communication layer in 5G environment was put forward.At first,the forwarding and control element separation and the reconfigurable control technology were used to reconstruct the 5G environment system framework,so as to strengthen the overall performance of an independent communication network.And then,the multi-scale wavelet packet analysis method was used to obtain the distributed hidden abnormal traffic detection principle.Moreover,the intrusion interference signal in network communication was analyzed.EMD was used to decompose signal information and thus to determine the threshold of the intrusion interference signal.The fractional power of the Fourier transform was introduced,and then the high-order cumulant slice factor was used to suppress the signal noise in the link layer of network data.Meanwhile,the sensitive data detection method was used to obtain the network attack signal,and thus to effectively identify the malicious attack behavior in the network.Thus,the security of the signal in the independent communication layer was guaranteed.Experimental results show that the proposed method can effectively reduce the malicious attacks in the process of network communication,and thus make the communication information transmission more secure.
