Research On Network Security Problems And Countermeasures Of Communication Technology

With the development of the times and the progress of society,the Internet begins to popularize in an all-round way,and the security of network information will become extremely critical.Now is the network era,network insecurity,national security will certainly be affected.Therefore,the importance of network security is naturally self-evident.In reality,the mobile Internet,an invisible thing,is not calm.Bank card account information stolen,personal phone computer hijacked by the virus,become bitcoin digger;every day a variety of network information fraud......Nowadays,various online security problems make people frequently recruit.At the meeting on network security and information held by Xi Jinping in 2016,the importance of network security and information in the 13 th Five-Year Plan was reiterated again,and the speech made the overall arrangement and requirements for the related work.Based on the analysis of the network structure,construction scheme,fault analysis and treatment of Houma egovernment network,the advantages of mobile communication technology are found.At the same time,the paper points out and analyzes the weak infrastructure construction,imperfect technology,the existence of artificial interference factors and the lack of scientific supporting measures,especially the network security problems,and then,combining the characteristics and development of 5G technology,based on the application of mobile communication technology,How to solve the problem of network information dissemination and related application security in 5G is put forward.The main work of this paper is:1?The concept,structure and key technology of 4 G ? 5G communication technology network are expounded,and the characteristics of 4 G?5G communication technology network are analyzed,and the influence of 4 G ? 5G communication technology on network security is analyzed and studied.Taking theoretical analysis,literature analysis,case analysis,qualitative analysis and other analytical means,combined with the construction scheme of Linfen Houma e-government network and the problems arising from the use of cases,solutions and so on,the network security problems of mobile communication technology are analyzed and studied and obtains the research conclusions of this paper.Finally,how to further improve and optimize its network security level,put forward the corresponding countermeasures,which requires in-depth understanding of mobile communication technology in the development and application of network security technology and other specific implementation measures.The authentication of mobile network,the coordination between network and 4 G?5G network,and some methods are adopted to encrypt the communication data effectively,so that the security of 4 G?5G data can be improved better.
