Abstract:
A video resource file acquisition method includes: acquiring, by a terminal, a resource decryption key of a target video from a key management server; transmitting, by the terminal, a resource download request for the target video to a resource server of the target video; after receiving the resource download request for the target video, acquiring, by the resource server, a resource encryption key of the target video from the key management server; encrypting, by the resource server, a resource file of the target video by using the resource encryption key and feeding back, by the resource server, the encrypted resource file to the terminal; and after receiving the encrypted resource file, decrypting, by the terminal, the encrypted resource file using the resource decryption key.
