AI Technical Summary

Benefits of technology

The technical effect of this patented technology lies between two processes - one for making it secure against unauthorized access by an authorised user or other entity while another involves encrypting data packets sent over networks like Ethernet without requiring any changes made during network administration. This makes it easier than previous methods because no new servers are needed instead of reconfiguring them when adding devices into their own system.

Problems solved by technology

This patented technical problem addressed by the current method for accessing wireless local area networks (WLAN), which requires an Access Control Protocol/802.1x session between two AC Devices that require complex configurations or other similar procedures when connecting to different types of WIFI hotspots like Hotspot 2.0).

Embodiment Construction

[0040]In the prior art, the 802.1X authentication process and the 802.1X encryption process need to be performed on the AC device; when 802.1X authentication is configured on the AC device, an unknown source MAC (Media Access Control, Media Access Control) address will be issued to discard and The 802.1X protocol message is sent to the CPU (Central Processing Unit, central processing unit) rules, so when the client fails to pass the authentication, only the 802.1X protocol message will be sent to the CPU for processing, and other messages will be discarded; when the client After the authentication is successful, the AC device will issue the MAC forwarding table entry. When it receives a message later, it will check whether the MAC forwarding table entry exists. If it exists, it will forward the message normally.

[0041] However, in the above process, 802.1X authentication needs to be performed on the AC device, and the authentication server needs to be configured with relevant...

Abstract

The invention discloses an 802.1X authentication method and equipment. The method comprises the following steps that: AC (access controller) equipment receives an EAPOL (extensible authentication protocol over lan) message which is forwarded by AP (access point) equipment from a client; if the EAPOL message is not an EAPOL-KEY message, the AC equipment transmits the EAPOL message to a BAS (broadband access server) if the target address of the EAPOL message is a multicast address; and if the EAPOL message is the EAPOL-KEY message, the AC equipment generates a key message by utilizing the EAPOL-KEY message, and transits the key message to the AP equipment. In the 802.1X authentication method and equipment, the configuration of an authentication server can be simplified.
