Embodiment 1

[0050] like figure 1 As shown, this embodiment proposes an anti-attack intranet data transmission method, the method comprising:

[0051] S1. The local intranet gateway encrypts the intranet data in the local intranet;

[0052] S2. Send the encrypted internal network data to the local external network gateway through a dedicated channel, and the local external network gateway sends the encrypted data to the external network;

[0053] S3. The remote external network gateway obtains encrypted data from the external network, checks the encrypted data and sends it to the remote internal network gateway through a dedicated channel;

[0054] S4. The remote intranet gateway decrypts the encrypted data to obtain the intranet data in the local intranet.

[0055]In this embodiment, the network is divided into an internal network and an external network. The internal network is a private network of a unit or organization, and its important information can only be used in the internal n...

Embodiment 2

[0063] like figure 2 As shown, this embodiment proposes an anti-attack intranet data transmission system, the system includes: a local intranet gateway, a remote intranet gateway, a local extranet gateway and a remote extranet gateway,

[0064] The local intranet gateway is used to perform protocol processing and encryption processing on intranet data in the local intranet, and send the encrypted intranet data to the local extranet gateway through a dedicated channel;

[0065] The local extranet gateway is used to transfer the encrypted intranet data, and send the encrypted intranet data to the extranet;

[0066] The remote external network gateway is used to obtain the encrypted internal network data in the external network, and check the encrypted internal network data in the external network, and then send the checked encrypted internal network data to the remote internal network gateway through a dedicated channel ;

[0067] The remote intranet gateway is used to decryp...

Abstract

The invention relates to the field of information communication, in particular to an anti-attack intranet data transmission method and system, which solves the problems of low security and practicality during the conventional information transmission process. The method comprises the following steps: a local intranet gateway carries out encryption processing of intranet data in a local internal local area network (LAN); the encrypted intranet data is sent to a local extranet gateway through a special channel, and the local extranet gateway sends the encrypted data to an extranet; a remote extranet gateway acquires the encrypted data from the extranet, examines the encrypted data, and sends the examined data to a remote intranet gateway through a special channel; and the remote intranet gateway decrypts the encrypted data to obtain the intranet data in the local internal LAN. The method and system provided by the invention has the advantages that the data is transmitted between the internal LANs in different areas through extranet switching, and transmitted information is encrypted, so that the information security is improved, benefits from the extranet are utilized, and the anti-attack capability is greatly higher than that of the traditional virtual private network (VPN) system.

Description

technical field [0001] The invention relates to the field of information communication. Background technique [0002] With the rapid development of the Internet and information technology, the relationship between the network and people's lives is getting closer and closer, and many activities are also transferred to the Internet (or Internet of Things, MAN and other wide area networks), such as online shopping, online banking, electronic Commerce, e-government, etc. At the same time, due to the openness of the Internet itself, it also faces many security problems. [0003] Among them, some activities will involve particularly important information. Such as e-government, the information in it may affect the national economy and people's livelihood. Another example is the financial system, which involves huge amounts of money. [0004] For such activities, one solution is physical isolation. Information is stored on the internal network, while the internal network and the...
