[0033] The encryption component includes a second USB interface module, a second main control module and an encryption chip.

The encryption chip is connected to the second main control module via an SDIO3.0 interface. The encryption chip is used to encrypt and decrypt the received network data. In this embodiment, Figure 5As shown, the first USB interface module and the second USB interface module are both USB type A interfaces.

[0034] The first main control module and the second main control module can both use i.MX6ULL chips based on the ARM Cortex-A7 core to run the Linux operating system and encryption service program on them. The encryption service program uses the Linux virtual network card technology to obtain network data packets. Before sending network data to the communication host, the protocol of the network data is first parsed to extract the payload data, input into the encryption component for encryption, and then restored to a standard network protocol packet for sending out. At the same time, when the encryption component receives the network data, it first parses the protocol of the network data to extract the payload data, inputs into the encryption component for decryption, and then restores to a standard network protocol packet and routes it to the communication host. At the same time, the first main control module uses the Linux virtual driver technology to transform the Linux kernel, and configures the network card driver for the type-c interface module of the gateway host; when the gateway host after the operating system kernel is transformed is inserted into the communication host, the system starts to perform hardware self-test first, and then loads the network card driver. After the network card driver is successfully loaded, the communication host identifies the gateway host as a network card device, and thereafter the communication host uses the external gateway host as an external network card for network communication.

[0035] When performing encryption and decryption services, the encryption chip can filter and encrypt network data according to the configuration file. The filtering parameters include parameters such as IP address, MAC address, port number and protocol type. The filtering parameters can be combined to filter out the data payload that needs to be encrypted and decrypted. If the filtering conditions are met, the data payload is extracted and sent to the encryption component for encryption and decryption before being sent or routed to the communication host. If the filtering conditions are not met, the data payload is directly sent or routed to the communication host without the encryption component. The encryption chip includes an encryption algorithm unit and a key storage unit. The encryption algorithm unit stores a symmetric encryption algorithm, and the key storage unit stores a symmetric key. The second USB interface module receives the payload data input by the gateway host in real time, uses the symmetric key and symmetric encryption algorithm stored in the encryption chip to encrypt and decrypt the data, and then outputs it to the gateway host. The encryption method involved in this embodiment is a prior art and will not be described in detail here.

[0036] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
