Abstract

The invention discloses a method and device for generating an encrypted video file library and a method and device for distributing and decrypting videos. The method for generating the encrypted videofile library comprises the steps: splitting a video file into at least one video fragment file with a fixed duration based on a preset HLS protocol; copying the video fragment file to obtain at leasttwo same target video fragment files; allocating a unique key to the target video fragment file, and encrypting the corresponding target video fragment file by using the key to obtain an encrypted video fragment file library. By adopting the method provided by the invention, the compatibility is improved; a terminal does not need to pre-embed a security code or a secret key, and therefore the universality and the usability are higher; the dynamic random key sequence is used, and therefore the method has relatively high anti-unauthorized playing security, stronger attack resistance and highersecurity level.

Description

technical field [0001] Embodiments of the present invention relate to the field of data encryption protection, in particular to a method and device for generating an encrypted video file library, and a video distribution and decryption method and device, and also to an electronic device and a computer-readable storage medium. Background technique [0002] At present, content protection technologies commonly used when playing videos based on H5 (html5) include: anti-hotlinking, and content encryption based on HLS or DASH. Among them, the content transmitted by the former is plain text, which is only transformed or authenticated on the URL of the streaming media; the content transmitted by the latter is cipher text, and the transmitted content key is then plain text. With the rapid development of Internet technology, in the application scenarios of mobile Internet, there are many non-APP video playback scenarios based on H5. Using the above method can no longer effectively pro...
