[0022] figure 1 It is a schematic diagram of the network attack protection system provided in the first embodiment. Such as figure 1 As shown, the system 100 includes a client 10 , a protection server 20 and a web server 30 . The client 10 and the protection server 20 can be connected through the Internet, and the protection server 20 and the network server 30 can be connected through the intranet of the enterprise.
[0023] Specific examples of the client 10 include: personal computers, smart phones, tablet computers, media players and any other electronic devices with Internet capabilities. The client 10 uses various network services provided by the network server 30 through the application programs (such as game client programs, instant messaging client programs, etc.) running in it.
[0024] refer to figure 2 , which is figure 1 The interaction diagram of the network attack protection system running. Such as figure 2 As shown, the client 10 first prepares the data...

[0030] image 3 It is a flow chart of the network attack protection method provided in the second embodiment, which can be used for such as figure 1 In the protection server 20 shown. Such as image 3 As shown, the method includes the following steps:
[0031] Step S210, receiving data submitted by the client.
[0032] Such as figure 2As shown, the client 10 first prepares the data to be sent. Specifically, the above-mentioned application programs will generate data that needs to be sent to the network server 30 during operation, such as recorded audio / video data, or user operation data in the game client program. Then, the client 10 can obtain the first verification value. After obtaining the first verification value, the client 10 can attach it to the data to be sent. Further, the client 10 sends data to the protection server 20 , and sends the data packet to the protection server 20 . Correspondingly, the protection server 20 receives the data submitted by the clie...

[0041] Figure 4 It is a flow chart of the network attack protection method provided in the third embodiment, and the method can be performed by figure 1 The system shown executes. Such as Figure 4 As shown, the method includes the following steps:
[0042] Step S310, the client appends the first verification value to the data to be sent, and sends the data to be sent to the protection server.
[0043] Such as figure 2 As shown, the client 10 first prepares the data to be sent. Specifically, the above-mentioned application programs will generate data that needs to be sent to the network server 30 during operation, such as recorded audio / video data, or user operation data in the game client program. Then, the client 10 can obtain the first verification value. After obtaining the first verification value, the client 10 can attach it to the data to be sent. Further, the client 10 sends data to the protection server 20 , and sends the data packet to the protection server ...
