File transfer method based on file mapping encryption

Abstract

The invention discloses a file transfer method based on file mapping encryption. The file transfer method comprises the steps of: (1) compressing a file to be transferred; (2) subjecting the compressed file to binary encryption; (3) calculating and recording an MD5 value of the encrypted file; (4) uploading the encrypted file to a specified file server; (5) parsing a JSON string returned after successful upload, and intercepting a URL for file download; (6) creating a file message and a JSON string on the basis of a secret key encrypted in the step (2), the MD5 value obtained in the step (3) and the URL obtained in the step (5); (7) and sending the file message and the JSON string thereof by means of HTTPS. The file transfer method has the advantages of adopting a powerful compression algorithm, satisfying high compression of large files, providing an efficient transferring speed, ensuring security in the file transfer process by encrypting the file, and effectively guaranteeing transfer security of users.

Description

technical field [0001] The technology applied for in the present invention belongs to the field of data transmission methods in computer networks, and in particular relates to a file transmission method based on file mapping encryption proposed to ensure efficiency and security in the process of data file transmission. Background technique [0002] With the continuous development of network technology, more and more users begin to obtain the information they need through mobile network or Internet connection. The transmission of information on the network is carried out through data files, and different data files are sent and received according to instructions between users. With the continuous increase and expansion of the amount of transmitted data, the amount of file data transmitted on the network has increased geometrically. With the continuous improvement of communication technology in network bandwidth, the increase speed of bandwidth is far from the increase of data...

Problems solved by technology

[0004] In order to overcome the defects of resource waste and low security in the existing file network transmission, this technical solution uses file compression technology to compress the files to be transmitted with a high compression ratio through a compression algorithm according to the file structure, so that the compressed files can be compressed as much as possible It may be small, thereby greatly improving the speed of file transfer. At the same time, through the file encryption algorithm, the compressed file is binary encrypted and uploaded to the designated file server
