Embodiment

[0045] Combine now image 3 , the security access process of the present invention is described in detail: when the security terminal user and the two-layer access device have established a physical connection, the security terminal sends an EAPOL authentication start message to the two-layer access device according to the standard EAPOL protocol, and starts the 802.1 For xR authentication, the Layer 2 access device sends an EAP identity authentication request message to the security terminal, requiring the security terminal to submit a user name. The security terminal responds with an extended EAP identity authentication response message to the Layer 2 access device. The response message contains user name information and security access tag information. The Layer 2 access device records the response message with the security mark, and submits the user name to the RADIUS authentication service. The RADIUS authentication server generates a 128-bit challenge, and responds to t...

Abstract

The invention discloses a safe access method based on a extended 802.1x authentication system, wherein the method which is based on EAPOL standard protocol expands EAPOL protocol identity authentication response message of authentication requestor and adds secure access mark to ensure that the authentication point control enters the safe access procedure; and an authentication server and a strategy server adopt authentication point mutual security level information message to realize that the authentication requestor, namely the terminal user accesses the network through a two-level access device safely and reliably. The invention can better satisfy the access control of the two-level access device to the terminal by expanding standard EAPOL protocol; and the truth and credibility of edgedevice of access network can be fully guaranteed while the traditional access authentication mode is not changed.

Description

technical field [0001] The invention relates to the access technology of data communication, in particular to the technology of terminal equipment securely accessing through the two-layer access equipment by using the 802.1x protocol. Background technique [0002] With the deepening of network applications, network security problems are becoming more and more serious. Security problems including denial of service attacks, viruses, hacking, spyware, phishing, etc. are more and more likely to occur, and the harm they bring is also becoming more and more serious. , becoming a major threat to Internet security. Traditional networks defend against security attacks through layered security, such as providing increasingly higher levels of security protection for network perimeters, critical network segments, and application-oriented authorization; these models provide comprehensive network access, can protect resources, and prevent external Threats and illegal application access, ...
