Abstract

The invention provides a file transfer processing method and system and terminals. The method includes the steps that the file transmitting terminal encrypts an original transfer file to obtain an encrypted file; the file transmitting terminal encrypts a secret key for decrypting the encrypted file to obtain an entitlement file; the file transmitting terminal transmits the encrypted file and the entitlement file to the file receiving terminal; the file receiving terminal decrypts the entitlement file to obtain the secret key for decrypting the encrypted file; the file receiving terminal obtains the original transfer file by decrypting the encrypted file according to the obtained secret key. Due to the file transfer processing method, the problem that in the related technology, a large safety problem exists when private files of an Internet user are applied is solved, and the effects of high encryption performance, convenient use and low safety cost are achieved.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a file transmission processing method, system and terminal. Background technique [0002] With the development of society, the Internet and mobile Internet have become an inseparable part of people's lives. While the Internet brings convenience and speed, the leakage of users' personal privacy has also become the focus of attention. In related technologies, instant chat software or even communication tools do not encrypt the content of the file itself during file transmission, that is to say, anyone else can open and view the file and obtain the content as long as they get the file. This is very poor security. If some confidential files need to be transmitted through instant chat software, or the computer is invaded by others, then some valuable personal privacy or confidential files may be easily leaked. [0003] Therefore, the use of private files of Internet users in relate...
