Problems solved by technology

One is that the encryption time will be very long, and the other is that the file can only be used after being decrypted after obtaining the file, which will be a waste of time for users and content publishers

Abstract

The invention relates to the Internet data transmission protection technology and provides a large file transmission protection method based on fragment encryption. The large file transmission protection method based on fragment encryption comprises the following steps: performing a fragment encryption operation before transmission to protect a large file; and performing a fragment decryption operation after the transmission to decrypt the large file for use. According to the large file transmission protection method, only the encryption protection is performed in the transmission process, thesame protection effect is achieved after the file is received, and the file can only be used after being normally decrypted; and meanwhile no encryption is required in the transmission process, and the transmission performance is obviously improved.

Description

technical field [0001] The invention relates to the technical field of Internet data transmission protection, in particular to a large file transmission protection method based on fragment encryption. Background technique [0002] Large file transfer protection mainly includes two aspects, one is the protection of the transfer process, and the other is that it cannot be used normally after being downloaded by an unknown person. In view of these two aspects, the current large file transmission protection technologies mainly include channel-based protection, such as HTTPS protocol transmission and file-based protection, which means that the file is completely encrypted or packed before transmission. However, there are obvious defects in the two technologies. [0003] The encryption method based on channel protection only protects the file from being stolen during transmission, but there is no way to guarantee whether the file is used by unauthorized people after the transmiss...
