Network access authentication method and device

Abstract

The invention provides a network access authentication method and device. The method includes the steps that an authentication server receives an authentication request sent by a network device, the authentication request carries an internet protocol IP address and a media access control MAC address of a terminal device to be authenticated; according to the IP address of the terminal device to beauthenticated, as well as the mapping relationship between each prestored IP address segment and each role task, the role tasks of the terminal device to be authenticated are determined, and in the corresponding MAC address of each stored IP address, when the corresponding MAC address of the IP address of the terminal device to be authenticated is not found, the MAC address and the IP address of the terminal device to be authenticated are stored to represent the pass of an authentication of the device to be authenticated; the mapping relationship between the MAC address of the device to be authenticated and the role tasks of the terminal device to be authenticated is sent to the network device. By adoption of the network access authentication method and device, the online efficiency of theterminal device is improved when there are a large number of terminal devices.

Description

technical field [0001] The present application relates to the technical field of network authentication, in particular, to a network access authentication method and device. Background technique [0002] In the enterprise network, a large number of terminal devices such as Internet Protocol (IP) monitoring, access control, and printers are usually deployed. For the sake of enterprise security, these terminal devices are usually required to access the network only after being authenticated by the enterprise authentication server. Perform their respective roles and tasks. For example, some terminal devices are responsible for monitoring the examination room, some terminal devices are responsible for monitoring the campus playground, and some terminal devices are responsible for dormitory access control, etc. [0003] Generally, in order to implement the above authentication mechanism, the Media Access Control (MAC) addresses of each terminal device that needs to access the net...

Problems solved by technology

[0004] The above authentication process needs to collect the MAC address of each terminal device in advance. When an enterprise needs to use a large number of terminal devices to perform a large number of different role tasks, this process will consume a lot of human resources and will affect the online efficiency of terminal devices.
