Embodiment Construction

[0035] The specific implementation of the present invention will be further described in detail below in conjunction with the drawings and embodiments.

[0036] Such as Image 6Shown is the network environment diagram of the embodiment of the present invention. In this embodiment, the LDAP server is connected to the AAA system, so that LDAP users can obtain the latest access control and differentiated services of the AAA system when they log in. Moreover, this embodiment also embodies the integration of network access authentication and network service authentication.

[0037] Such as Figure 5 As shown, it is a flow chart of AAA system authentication of 802.1x+RADIUS in the embodiment of the present invention. The implementation process of this embodiment includes the following steps:

[0038] (1) The NAS device sends an EAP-Request / Identify to the 802.1x client to request the user identity, which can also be said to be the user name.

[0039] (2) The 802.1x client respo...

Abstract

The invention discloses a method for information interaction and authentication between a RADIUS server and an 802.1x client, and a RADIUS system. The RADIUS system defines a series of request instructions and response specifications. When the RADIUS server needs to obtain additional information from the client, it uses the The Notification type message carries the request command and sends it to the 802.1x client, and the 802.1x client responds according to the corresponding response specification to complete the information exchange between the two. The present invention provides a safe authentication, authorization, and accounting (AAA) scheme for the broadband network, which solves the problem of combining the AAA system and the LDAP directory service, and enables users to be flexible in the case of unified authentication. Access control, which enhances the applicability of using RADIUS as an AAA system.

Description

technical field [0001] The invention relates to authentication, authorization and accounting (AAA) technology in the communication field, in particular to a method for information interaction and authentication between a RADIUS server and an 802.1x client and a RADIUS system thereof. Background technique [0002] IEEE 802.1x is called a port-based access control protocol, which provides a means of authentication and authorization for devices or users connected to a LAN based on the advantages of IEEE 802LAN; the full name of RADIUS is Remote Access Dail-In User Service (remote user dial-up authentication service) is one of the most commonly used authentication and accounting protocols at present. It is simple, safe, easy to manage, and has good scalability, so it is widely used. 802.1x combined with RADIUS can provide a secure Authentication, Authorization, and Accounting (AAA) scheme for broadband networks. [0003] The AAA architecture of 802.1x+RADIUS includes three impo...
