Embodiment Construction
[0030] The network communication equipment referred to in the present invention is a general term, and the equipment with the network communication data transmission function is all network communication equipment. figure 1 Please refer to the technical solution, and will not go into details.
[0031] It should be noted:
[0032]The first network includes modules or devices that are isolated from the external network in the first network security isolation device, that is to say, the first key group can be stored in these modules or devices. Similarly, the network communication data combination encryption process of the present invention is performed by the first key group. The encryption and decryption of communication data sent by a network communication device or sent to the first network communication device can also be completed by these modules or devices;
[0033] The second network includes modules or devices that are isolated from the external network in the second n...

A network communication data combination encrypted transmission method based on network security isolation technology, the first network security isolation device is respectively connected to the first network and the external network, the second network security isolation device is respectively connected to the second network and the external network, ..., the Nth network security The isolation device is respectively connected to the Nth network and the external network, N is a natural positive integer greater than or equal to 2, the first network includes the first network communication equipment and the first key group, and the second network includes the second network communication equipment and the second network communication equipment. Second, the secret key group. Similarly, the Nth network includes the Nth network communication device and the Nth secret key group. The present invention isolates malicious attacks from external networks and establishes a local safe and trusted network. There are loopholes, and malicious attacks still cannot touch the communication data encryption and decryption process and the key group. The use of AES advanced encryption algorithm or RSA encryption algorithm and more than 128-bit secret key can ensure the encryption of communication data and ensure the credibility of encrypted transmission.
Description
technical field [0001] The invention relates to the field of methods for encrypted transmission of network communication data, in particular to a combined encrypted transmission method of network communication data based on network security isolation technology. Background technique [0002] Network communication data encryption and transmission technology is the cornerstone of trusted network communication data transmission. The key used for network communication data encryption and transmission is the core of security protection in the process of trusted network communication data transmission. Algorithms, such as using AES advanced encryption algorithm or RSA encryption algorithm with more than 128-bit key, can ensure that the network communication data encrypted and transmitted within a valid time will not be cracked. All networks are connected to external networks. If the network communication device itself or the network where it is located is maliciously attacked from...
