Problems solved by technology

[0014] It can be seen from the above that in the prior art, after the user terminal passes the authentication, the user terminal needs to initiate a DHCP request, and the DHCP server assigns an IP address to the user terminal. cooperation between
Therefore, in the authentication system based on the above authentication method, various devices including DHCP server need to be deployed, and the cost of networking is relatively high.

Embodiment Construction

[0066] The invention provides a method and equipment for allocating IP addresses in the authentication process of user terminals. The authentication server directly allocates IP addresses for user terminals, thereby eliminating the need to deploy a DHCP server in the network and simplifying the authentication process.

[0067] Hereinafter, the authentication based on the 802.1x protocol is taken as an example, and the present invention will be further described in conjunction with the accompanying drawings.

[0068] Firstly, the structure of the authentication response message used to transfer the IP address information in this embodiment will be described. In this embodiment, the existing authentication response message is further extended.

[0069] In the 802.1x protocol, EAPoL packets are exchanged between a user terminal (supplicant) and an access device (authenticator). Authentication servers usually use RADIUS or TACACS protocols. Taking the RADIUS protocol as an examp...

Abstract

The invention provides a method which is used for distributing an IP address in the process of authorizing a user terminal and a device thereof, wherein, after an authorizing server is authorized at the user terminal, the IP address is distributed to the user terminal. By adopting the method and the device of the invention, a DHCP server is not needed to be deployed in a network, thus reducing the cost of network building.

Description

technical field [0001] The present invention relates to the technical field of IP address allocation, in particular to a method and device for allocating IP addresses during user terminal authentication. Background technique [0002] IEEE 802.1x protocol, as a port-based LAN access control and authentication technology, can restrict unauthorized users from accessing the enterprise LAN. Before the user terminal is authenticated, the port corresponding to the user terminal will remain closed, and the 802.1x protocol only allows the user's authentication packets to pass through the port; after the authentication is passed, the port is opened, and the normal data packets of the user terminal can through this port. The 802.1x technology provides a flexible network access control method that separates authentication and services in the Ethernet environment. [0003] The 802.1x-based authentication technology uses Extensible Authentication Protocol over LAN (EAPoL, Extensible Aut...
