Embodiment Construction

[0024] The technical solutions of the present invention will be further described in detail below in conjunction with specific embodiments.

[0025] see figure 1 , an HLS live index list encryption anti-leeching method, the main steps are as follows:

[0026] First, in step 101 , the client 10 obtains a user token through the client authentication server 20 of the system, and binds the user token with the IP address of the client 10 . When the client 10 obtains the user token through the client authentication server 20, there will be a GEOBLOCK (IP restriction) mechanism, and it cannot log in in an unauthorized country.

[0027] The user token is bound to the client IP and has a time limit, and will become invalid after expiration. Each user's token is different, and a new token will be issued after re-login. The original token will automatically become invalid, and the user needs to log in again.

[0028] The client authentication server 20 provides an interface for obtain...

Abstract

The invention discloses an HLS live broadcast index list encryption anti-stealing-link method. The method mainly comprises the following steps that 1, a client side acquires a user token through a client authentication server of a system, and the user token and the IP address of the client side are bound; 2, the client side acquires an M3U8 playing address; 3, the client side acquires a URL address of a secret key and M3U8 enciphered data; 4, a standard M3U8 playing list text is acquired; 5, a TS file is acquired and played, and the client side downloads the video section TS file from a content distribution server through a TS file downloading address in a decrypted standard M3U8 playing list. According to the HLS live broadcast index list encryption anti-stealing-link system, the content is encrypted when the client side acquires M3U8 files, the video file address cannot be obtained even though the files are directly downloaded, therefore, an anti-stealing-link function is achieved, it is avoided that a large number of CPU resources need to be consumed during TS file decryption, and the aim of smooth playing of low-performance equipment is solved.

Description

technical field [0001] The invention relates to the field of computers, in particular to an HLS live index list encryption anti-leeching system and method. Background technique [0002] The HTTP Live Streaming (HLS) playback framework adopts the content encryption technology of HTTP Live Streaming (HLS) Extension, which sends encrypted video streams to the client through HTTP, and the client obtains the decryption key through the DRM server to decrypt the media file and then plays it. Terminals include mainstream terminals such as STB, mobile terminals, and Website. The DRM link uses Advanced Encryption Standard (AES-128), HTTPS protocol, and other technologies to seamlessly protect content from illegal downloads or piracy. [0003] In the traditional HLS DRM solution, the TS video file itself is encrypted and decrypted, so the hardware requirements are relatively high. Decrypting TS video files on devices with relatively poor hardware performance is relatively slow, and v...
