User based control method in IEEE802.1x authentication

Abstract

The invention provides a user based controlling method in IEEE 802.1x identification which comprises, when a port enables the 802.1x identification function, subjecting the port to related initialization, the user passes the identification on the port and arranging a logic port on the port based on the user, in IEEE 802.1x identification, the logic port only opens to users which passes identification, whose business messages can go through the physical port normally.

Description

Technical field [0001] The invention belongs to the field of computer network communication, and in particular relates to a method for respectively opening logic ports based on users in IEEE 802.1x authentication. Background technique [0002] IEEE 802.1x is called Port based network access control protocol, which provides a means of authenticating and authorizing devices or users connected to a LAN based on the advantages of IEEE 802 LAN. [0003] The 802.1x protocol is derived from IEEE 802.11 wireless Ethernet, and its original design is to provide point-to-point physical or logical port access authentication for wireless LANs. Therefore, after it is introduced into broadband Ethernet, it inevitably has certain limitations. The most prominent problem is that the operation object of 802.1x authentication technology is the port. As a port-based network access control technology, the 802.1x protocol only focuses on the switch of the LAN port. When the authentication is passe...

Problems solved by technology

Compared with Ethernet with shared channels, this feature has great security risks. After the port is opened, other users can freely access without authentication, resulting in the problem of uncontrollable illegal access.
