System and method for on-demand dynamic authentication and connection of users in local area network

Abstract

The present invention relates to the field of computer networks, in particular to a system and method for dynamic authentication and connection of users in a local area network on demand, which consists of three planes, which are respectively a data plane, a control plane and a management plane, and the connection between the data plane and the control plane Through Openflow protocol communication, the control plane and management plane run in the operating system and interact through inter-process communication. Among them: the data plane includes an Openflow switch, which is responsible for data interaction with the control plane, according to the flow issued by the forwarding policy module The table performs data forwarding; the control plane includes a user name resolution module and a forwarding policy module; the management plane includes a user management module, a group management module and a connection management module. The invention solves the risk problem that the user host in the ordinary local area network is online for a long time and the network topology is basically unchanged, and an attacker can use this condition to attack and steal information.

Description

technical field [0001] The invention relates to the field of computer networks, in particular to a system and method for dynamic authentication and connection of users in a local area network on demand. Background technique [0002] With the increasing demand and use of digital products, digital office has become an indispensable condition. The large-scale local area networks established by companies, schools and some public places are also increasing, and there is an increasing need to build a safe and stable local area network. However, there are a lot of hidden dangers in the current network environment. The user hosts in the LAN are connected to the switch, and the user hosts are online for a long time, so that the attacker can easily obtain the network topology structure, and can perform long-term control and monitoring on the user hosts; a large number of communication messages are transmitted through broadcasting, and the communication network is networked. Shaped st...
