Problems solved by technology

[0004] At present, in addition to the HTTPS request messages initiated by browsers, many applications also initiate a large number of HTTPS request messages. For these HTTPS request messages initiated by non-browsers, the authentication device will also intercept and redirect them. , the HTTPS request message initiated by a non-browser is actually an invalid HTTPS request message, which can be identified as HTTPS noise. Even if the authentication device pushes the authentication page, the application cannot display it, and these invalid HTTPS request messages will consume the authentication device. A large number of resources, and even affect the processing of normal HTTPS request packets

Embodiment Construction

[0043] In order to filter out the HTTPS noise in the HTTPS request message and reduce the noise in the HTTPS redirection, the inventor conducted a very in-depth research and found that:

[0044] For HTTPS redirection, only HTTPS request packets that respond to redirection that are manually clicked by the user or automatically triggered by the system foreground are not HTTPS noise, but normal HTTPS requests, and other HTTPS request packets can be defined as HTTPS noise .

[0045] According to user behavior, the following table 1 lists the generation of HTTPS request packets and the determination of whether HTTPS request packets are HTTPS noises.

[0047] Table 1

[0048] According to the hierarchical structure of the network, the characteristics of different levels can be considered to analyze and process the HTTPS noise, as shown in Table 2 below.

Abstract

The invention discloses a noise reduction method and device for HTTPS redirection. The method includes: receiving a first TCP request message sent by a first terminal; obtaining the source IP address and destination IP address carried by the first TCP request message; address, source port, and destination port; determine whether a set number of packets carrying the source IP address, the destination IP address, and the destination IP address have been received within the set duration before the receiving moment of the first TCP request message. The second TCP request message of the port; if it is determined that the second TCP request message of the set number has been received within the set duration, then determine the source port carried by the first TCP request message and the Whether the source port carried by the second TCP request message changes according to the set rule; if it is determined that the source port carried by the first TCP request message and the source port carried by the second TCP request message change according to the set rule, Then discard the first TCP request packet. This solution can filter HTTPS noise.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a noise reduction method and device for HTTPS redirection. Background technique [0002] Hyper Text Transfer Protocol over Secure Socket Layer (HTTPS) is a hypertext transfer protocol (Hyper Text Transfer Protocol over Secure Socket Layer, HTTP) channel aimed at security, simply speaking, it is a secure version of HTTP . That is, the Secure Sockets Layer protocol (Secure Sockets Layer, SSL) is added under HTTP, and SSL is the security basis of HTTPS. [0003] The HTTPS redirection technology is that the authentication device intercepts the HTTPS request message initiated by the terminal, and then fakes the destination site to perform Transmission Control Protocol (TCP) handshake and SSL handshake with the terminal, and then redirects and pushes the authentication page to the terminal after the connection is established. . [0004] At present, in addition to the HTTPS re...
