Embodiment 1

[0055] see figure 1 , the data transmission method provided by the embodiment of the present invention includes:

[0056] Step S110: Send the first ID code and original data to the data receiving end. After receiving the first ID code and original data, the data receiving end verifies the first ID code. When the verification is successful, it indicates that the sending end If the user is a legitimate user, the data receiving end sends back the second identification code and the receipt; when the verification fails, it indicates that the sending end is an illegal user, and the data receiving end discards the original data and / or issues an alarm.

[0057] Step S120: After receiving the second identity code and the return receipt, verify the second identity code; when the verification result is successful, confirm that the data receiving end has successfully received the original data; Correct, resend the first ID code and original data.

[0058] It should be noted that, the em...

Embodiment 2

[0102] see Figure 7 , the embodiment of the present invention also provides a data transmission system, including:

[0103] A data sending module 100, configured to send the first identity code and original data to the data receiving end;

[0104] The first verification module 200 is used for verifying the first identity code after the data receiving end receives the first identity code and the original data, and if the verification is successful, the data receiving end returns the second identity code and the return receipt When sending, the second identity code and receipt are received, and the second identity code is verified; when the verification result is successful, it is confirmed that the data receiving end has successfully received the original data; when the verification result is failure, it means that the receiving end is incorrect , and resend the sender ID code and original data. Wherein, if the data receiving end fails to verify the first identity code, it i...

Abstract

The invention discloses a data transmission method and a data transmission system. The data transmission method comprises the steps that a first identity identification code and original data are sent to a data receiving terminal, the data receiving terminal receives the first identity identification code and the original data and carries out verification on the first identity identification code, and the data receiving terminal returns a second identity identification code and a receipt when the verification is successful; the second identity identification code and the receipt are received, and verification is carried out on the second identity identification code; the data receiving terminal is confirmed to receive the original data successfully when the verification is successful; and encryption is carried out on network connection in a transmission layer. The data transmission method disclosed by the invention ensures the security of data transmission on the one hand, and avoids encryption for transmitted data on the other hand, thereby improving the data transmission efficiency.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a data transmission method and system. Background technique [0002] At present, for data exchange, the following traditional methods are usually adopted: [0003] Generally, for the data exchange of large batches of data files, FTP (File Transfer Protocol, File Transfer Protocol) is usually used for uploading, that is, the user sends commands to the server program through the client program, and the server program executes the commands issued by the user and transfers the results of the execution to the server program. Returning to the client, this is the most basic form of data transmission, and the security of data upload and download cannot be guaranteed. In order to ensure the security of data upload and download, users can also use SFTP (SecureFileTransferProtocol, Secure File Transfer Protocol) to transfer data. However, since SFTP needs to encrypt the tran...
