Problems solved by technology

[0003] In traditional network data transmission, if it is necessary to strengthen the transmission security at the terminal, the user often needs to grant ROOT authority to process the terminal transmission process. After obtaining the ROOT authority, the highest authority of the system is obtained, and any file in the system can be accessed. Including system file execution operations, there are security risks

Embodiment Construction

[0025] figure 1 A graph of the application environment running for a data transfer method. Such as figure 1 As shown, the application environment includes a terminal 110, a transfer server 120, and a first server 130, wherein the terminal 110, the transfer server 120, and the first server 130 communicate through a network.

[0026] The terminal 110 may be a smart phone, a tablet computer, a notebook computer, a desktop computer, etc., but is not limited thereto. The terminal 110 converts the network protocol IP data packet sent from the virtual network interface into a transport layer protocol data packet through the VPN service and encrypts it, then sends it from the transport layer network to the transit server 120, and the transit server 120 decrypts it and sends it to the first server 130. The VPN service intercepts IP data packets and converts them into transport layer protocol data packets. The data packets can be encrypted and sent from the transport layer network to ...

Abstract

The invention relates to a terminal data transmission method and device. The terminal data transmission method comprises the steps of: intercepting a network protocol data packet sent to a virtual network interface on a network layer by a VPN (Virtual Private Network) service, and acquiring a file descriptor corresponding to the VPN service; according to the file descriptor, reading the network protocol data packet, and converting the network protocol data packet into a transmission layer protocol data packet; and encrypting the transmission layer protocol data packet to obtain an encrypted data packet, and sending the encrypted data packet to a transit server from a transmission layer network, so that the transit server forwards the encrypted data packet to a corresponding target server after decrypting the encrypted data packet. Safety of terminal data transmission also can be improved without acquiring a system permission.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a method and device for terminal data transmission. Background technique [0002] With the development of computer technology, it is more and more common to obtain information, study and work through the Internet. During the user's networking process, if the user is connected to an insecure network, criminals can use methods such as ARP (Address Resolution Protocol, Address Resolution Protocol) attacks to obtain information such as the user's account number and password. [0003] In traditional network data transmission, if it is necessary to strengthen the transmission security at the terminal, the user often needs to grant ROOT authority to process the terminal transmission process. After obtaining the ROOT authority, the highest authority of the system is obtained, and any file in the system can be accessed. Including system file execution operations, there are pote...
