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...
