Abstract

The invention relates to a data file transmission method. An initial key is firstly built between a transmitting end and a receiving end, and then, the data file is blocked for transmission. Each block uses a different key for encryption, data file transmission is thus high in safety, and the data file transmission efficiency is not influenced.

Description

【Technical field】 [0001] The invention belongs to the field of computers and networks, and relates to data transmission on the network, in particular to a data file transmission method. 【Background technique】 [0002] In recent years, with the popularization of computers and networks, a large number of information exchanges between individual users and enterprises have been transferred to the Internet, and the data exchange between the two parties is completed through the Internet. A typical requirement is to transmit a certain data file, such as word document, PDF document, etc., between two parties on the Internet. [0003] In the prior art, there are many ways to transfer data files on the network. The direct file transfer methods include FTP file transfer protocol, SCP safe copy, etc., and the indirect data file transfer methods can be, for example, email transfer, network disk transfer, etc. Save and so on. However, the existing file transfer methods are either too co...
