Embodiment 1

[0045] An embodiment of the present invention provides an information authentication method, such as figure 1 Said, said method comprises:

[0046] Step 101, obtaining domain name information;

[0047] Wherein, the domain name information is used to indicate the domain name of the network service; in the interaction process based on TLS, the domain name information is usually carried in the SNI field in the TLS initial protocol message, so as to realize the communication between the user UE, the gateway, and the server. Transfer of domain name information. Of course, the domain name field can also be carried in a user-defined field for delivery.

[0048] Specifically, the gateway device transmits the SNI field between the UE and the server through transparent transmission at the initial stage of TLS link establishment, and further parses the SNI field during the process of transmitting the SNI field to obtain domain name information.

[0049] Step 102, searching for the roo...

Embodiment 2

[0057] An embodiment of the present invention provides an information authentication method, such as figure 2 Said, said method comprises:

[0058] Step 1011, analyzing the domain name identification field to obtain domain name information;

[0059] Wherein, the domain name information is used to indicate the domain name of the network service; in the interaction process based on TLS, the domain name information is usually carried in the SNI field in the TLS initial protocol message, so as to realize the communication between the user UE, the gateway, and the server. Transfer of domain name information. Of course, the domain name field can also be carried in a user-defined field for delivery.

[0060] Specifically, the gateway device transmits the SNI field between the UE and the server through transparent transmission at the initial stage of TLS link establishment, and further parses the SNI field during the process of transmitting the SNI field to obtain domain name informa...

Embodiment 3

[0074] An embodiment of the present invention provides an information authentication method, such as image 3 Said, said method comprises:

[0075] Step 101, obtaining domain name information;

[0076] Wherein, the domain name information is used to indicate the domain name of the network service; in the interaction process based on TLS, the domain name information is usually carried in the SNI field in the TLS initial protocol message, so as to realize the communication between the user UE, the gateway, and the server. Transfer of domain name information. Of course, the domain name field can also be carried in a user-defined field for delivery.

[0077] Specifically, the gateway device transmits the SNI field between the UE and the server through transparent transmission at the initial stage of TLS link establishment, and further parses the SNI field during the process of transmitting the SNI field to obtain domain name information.

[0078] Step 102, searching for the roo...

Abstract

The embodiment of the invention discloses an information authentication method and a gateway device. The method comprises the following steps: obtaining domain name information by the gateway device; searching a root certificate to which a certificate corresponding to the domain name information belongs; and performing authentication processing on a server according to the root certificate to obtain an authentication processing result.

Description

technical field [0001] The invention relates to information processing technology, in particular to an information authentication method and gateway equipment. Background technique [0002] In order to implement content billing for hypertext transfer protocol (Hyper Text Transfer Protocol over Secure Socket Layer, HTTPS) messages, currently the industry generally adopts encryption-based layer, such as Transport Layer Security (Transport Layer Security, TLS) process The plaintext field carried in the initial negotiation message is the Server Name Indication (SNI), and the plaintext field SNI is used to identify the domain name information of the service, so that content charging can use the SNI field as a service type identification and Content billing field. [0003] However, if the client and the server cooperate to fake, that is, set the SNI field as a flow-free field, serious traffic theft will be caused. Therefore, how to verify the authenticity of the SNI field is an ...
