Problems solved by technology

[0005] Regardless of whether the IEEE 802.11i or WAPI standard is adopted, the process of authenticating certificate files involves a series of complex operations such as the generation, issuance, and import of certificate files. These operations require users to complete operations through configuration devices such as computers. Complicated, it may also lead to potential safety hazards of the system

Embodiment 1

[0023] The method for secure transfer of certificate files of the present invention is based on a system containing a wireless terminal module, a wireless access module and an authentication server. The wireless terminal module accesses the network through the wireless access module, and is suitable for wireless terminal module access during communication. The secure transmission of certificate files during the process of entering the network includes steps such as figure 1 , S101. Determine whether the wireless access module and the authentication server are located in the same device. If yes, execute step S102, the authentication server generates an access certificate file of the wireless access module and sends it to the wireless access module, and then executes step S105. The wireless access module may be a wireless access point AP. The wireless terminal module may be a wireless terminal device such as a mobile phone.

[0024] If the authentication server and the wireless acc...

Embodiment 2

[0030] In the first implementation, the general wireless terminal module or wireless access module establishes a connection with the authentication server through a network or the like, and this method has insecure factors. This embodiment is an improved embodiment.

[0031] The method for securely transferring a certificate file of the present invention includes steps such as figure 2 , S201. Determine whether the wireless access module and the authentication server are located in the same device. If yes, perform step S202, the authentication server generates an access certificate file of the wireless access module and sends it to the wireless access module, and then performs step S205. The wireless access module may be a wireless access point AP.

[0032] If the authentication server and the wireless access module are not in the same device, perform step S203. The wireless access module transmits the data request information of the wireless access module to the authentication s...

Embodiment 3

[0037] This embodiment discloses a system for securely transferring certificate files, such as image 3 , Which includes:

[0038] The authentication server is used to determine whether the wireless access module is located in the same device as it, and if so, generate an access certificate file of the wireless access module and send it to the wireless access module; receive the wireless terminal module sent Data request information, generate a terminal certificate file of the wireless terminal module according to the data request information, and transmit it to the wireless terminal module;

[0039] The wireless access module is used to receive the access certificate file sent by the authentication server;

[0040] The wireless terminal module is used to send data request information to the authentication server and receive the terminal certificate file sent by the authentication server.

[0041] When the authentication server and the wireless access module are not in the same devi...

Abstract

The invention discloses a method for safely transferring a certificate file and a system. The method is based on a system comprising a wireless terminal module, a wireless access module and an identification server. The wireless terminal module accesses network through the wireless access module. The method comprises the following steps: identifying whether the server and the wireless access module are in the same device, if true, the identification server generates an access certificate file of the wireless access module and transfers the access certificate file to the wireless access module; the identification server generates a terminal certificate file of the wireless terminal module according to the data request information transferred by the wireless terminal module and transfers the terminal certificate file to the wireless terminal module. According to the method for safely transferring the certificate file of the invention, the identification server can automatically generate the terminal certificate file or the access certificate file based on the data request information transferred by the wireless terminal module or the wireless access module without the operation of the collocation equipment such as a computer, then the implementation is very simply and convenient.

Description

Technical field [0001] The present invention relates to the field of communication, and in particular to a method and system for securely transferring certificate files in the communication process. Background technique [0002] WLAN (Wireless Local Access Network, wireless local area network) provides a high-speed wireless data access service. WLAN is currently one of the most popular technologies in the IT industry. The current security standards for WLAN mainly include IEEE 802.11i proposed by IEEE (Institute of Electrical and Electronics Engineers) and WAPI (WLAN Authentication and Privacy Infrastructure) with independent intellectual property rights in my country. ). [0003] 802.11i authentication can use 802.1X or shared key mode. IEEE802.1x 2001 defines a framework based on Extensible Authentication Protocol (EAP) overLANs, namely EAPoL. The requester and the authentication server are authenticated through the EAP protocol, the certificate file data is encapsulated in the...
