Embodiment Construction

[0054] The core idea of ​​the present invention is to divide the VLAN under the controlled port of the authentication device into two kinds of virtual VLANs: controlled VLAN and uncontrolled VLAN. Among them, for the controlled VLAN, it is forbidden to send any message in the unauthorized state without authentication, and the data message can be transmitted in the authorized state; for the uncontrolled VLAN, the data message is always allowed to pass.

[0055] Such as Figure 4 As shown, an authentication method of the present invention includes the following steps:

[0056] Step s401, configuring the authentication device and its controlled ports.

[0057] Specifically, the authentication device is configured to have an authentication function, and its port is configured as a controlled port with the authentication function.

[0058] Step s402, configuring a VLAN under the controlled port.

[0059] Configure the VLAN under the controlled port. The controlled port is furthe...

Abstract

This invention discloses an authentication method including the following steps: when a controlled port of an authentication device receives a message sent by an exchange device, it gets the kind of the message and VLAN of the terminal transmitting the message, then the device processes the message based on the kind, the VLAN and preset attribute of VLAN. This invention also discloses an authentication system.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to an authentication method and system. Background technique [0002] The way for users to access the LAN has evolved from the initial unprotected network access to simple Mac address binding, and now adopts PPPoE (Point to Point Protocol over Ethernet, Ethernet point-to-point protocol), Web, VPN (Virtual Private Network, virtual private network), wireless network WEP (Wireless Encryption Protocol, wireless encryption protocol), 802.1X authentication and other diversified access access systems, its security, efficiency and convenience have also been developed and improved rapidly . Due to various defects in the access control of PPPoE in the pure Ethernet environment, IEEE (Institute of Electrical and Electronics Engineers, Institute of Electrical and Electronics Engineers) officially promulgated the IEEE 802.1X standard in 2001, which is a port-based network interfa...
