Abstract

The invention provides an MAC address authentication method and apparatus. The method comprises the following steps: when a message is received, obtaining a source MAC address carried by in the message; querying whether the source MAC address is present in a preset illegal MAC address table entry; if not, determining the source MAC address as an unauthenticated MAC address; if the source MAC address is the unauthenticated MAC address, matching the source MAC address in a pre-stored white list, and determining that the source MAC address is authenticated, when a pre-stored legal MAC address is matched in the white list. By adopting the invention, the processing pressure on a core switch can be reduced, and the overall processing efficiency is improved. According to the invention, effective user authentication can be provided for providing a network environment with better quality and higher efficiency for the transmission of video traffic, and network attacks can be blocked to improve the network security.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular, to a method and device for authentication of MAC (Media Access Control, media access control) addresses. Background technique [0002] With the continuous development of network technology, the number of devices connected to the network and their application types has become larger and larger, and the network environment has become more and more complex. It even contains a large number of attack packets and illegal packets that steal network resources. [0003] In a video surveillance system, since the remote broadband access server BRAS (Broadband Remote Access Server) cannot provide effective user authentication, it is difficult to prevent illegal users from stealing network resources and cannot block network attacks. SUMMARY OF THE INVENTION [0004] Aiming at the defects of the prior art, the present invention provides a MAC address authentication method...
