Application Research Of Blockchain In WLAN Mesh Security Authentication

In recent years,the rapid development of the information age has made network security more and more important.And nowadays,with the development of wireless routing technology,WLAN has become a new network structure with high capacity,which can provide access services for a large number of terminals,and has high reliability and flexibility.Intelligent terminals use WLAN to connect to WLAN Mesh network to realize network connection.Many public places provide free public WLAN,and it needs relevant services to protect users who access WLAN network and protect the security of access users.In this paper,block chain technology and secure access of WLAN Mesh network are combined together,and then a new secure access method of WLAN Mesh based on IEEE802.11 s protocol is proposed.Using the technical characteristics of block chain technology,such as decentralization,distributed storage and distributed management,and combined them with encryption technology,the access user identity is securely authenticated and encrypted to achieve secure access to user terminals.After terminal access,the distributed management between terminals is completed to ensure the security of legitimate terminals and resist the access of illegal terminals.Based on this,this paper carries out the application research of block chain in WLAN Mesh security certification.The main research contents and achievements are as follows:1)Several commonly used access authentication schemes of WLAN Mesh are introduced and compared in this paper;the application of block chain technology in combination with authentication part and encryption part of access scheme is analyzed;and by using the important features of block chain technology that can't be tampered with,a scheme of WLAN Mesh secure access based on block chain technology is proposed,which greatly improves its security performance.The scheme is described and analyzed concretely.2)The overall design of WLAN Mesh secure access based on block chain technology is completed in this paper,including authentication module,encryption module and distributed autonomous management module.The secure access of meshnetwork is realized on Linux platform and the result state is obtained.Each authentication record will be treated as a transaction,all authentication records in mesh network will be treated as public accounts,and all user nodes will maintain together to achieve effective monitoring of malicious user attacks.Finally,the function and performance of authentication protocol are studied and analyzed in simulation experiment and system experiment,and the corresponding results are obtained.
