Problems solved by technology

However, 802.1X technology is a "authenticated and forget" technology, that is, it only conducts identity authentication when establishing a connection. Security poses hidden dangers
[0004] The existing 802.1X standard defines a "client-server" (Client-Server) mode to restrict unauthenticated users from accessing the network, but there is a technical problem of lack of network security protection measures after the user's initial authentication. Therefore it is necessary to provide a network access device that solves the above technical problems

Embodiment 1

[0027] This embodiment provides a network access device. The network access device includes a client device and a server device. The process authentication is performed between the client device and the server device by adding random values. If the process authentication passes, the The service message is passed, and at the same time, re-authentication is performed between the client device and the server device, and if the re-authentication fails, the client re-authenticates.

[0028] Specifically, the server-side device adds an entry of MAC, port number, user name and password of the client; the password in the entry of the password is stored using the RC4 encryption method; the client device adds the MAC of the server, port No., user name and password, and the password is saved using the RC4 encryption method. After the authentication is completed, the client can access the server.

[0029] Specifically, the re-authentication includes defining a threshold value, the server...

Abstract

The invention relates to a network access device, and solves the technical problem of lack of network security protection measures after initial authentication of a user. The device comprises client equipment and server equipment; process authentication is performed by adding a random value between the client equipment and the server equipment, and when the process authentication is passed, a service message is allowed to be passed; and meanwhile, re-authentication is also carried out between the client equipment and the server equipment, and if the re-authentication fails, a client re-carriesout the process authentication. By adopting the technical scheme, the problem is better solved; and the device can be applied to a communication technology.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a network access device. Background technique [0002] In IEEE 802 LAN, as long as the user can connect to the network device, it can be used directly without authentication and authorization. In this way, an unauthorized user can enter the network through devices connected to the LAN without any hindrance. This poses a potential hidden danger to network security. Network security is a must for all network equipment manufacturers. [0003] The Port-Based Network Access Control proposed by IEEE, that is, the 802.1X solution, is widely used as a LAN access method. 802.1X utilizes the physical access characteristics of IEEE 802 LAN to provide an authentication and authorization scheme for accessing the LAN. However, 802.1X technology is a "authenticated and forget" technology, that is, it only conducts identity authentication when establishing a connection. Safety brings...
