The specific implementation is described through the following embodiments.

Referring to Figure 1, it is a schematic flow diagram of a video processing method disclosed in the embodiment of the present application. The video processing method is applied to the server. The video processing method mainly includes the following steps:

S101: Obtain a video to be encrypted, and obtain an encryption key corresponding to the video to be encrypted.

Wherein, the server uploads the acquired video to be encrypted to the content management platform. The content management platform provides a storage function for storing the video to be encrypted.

The video to be encrypted is obtained from the content management platform through the server, and the encryption key corresponding to the video to be encrypted is obtained through the preset key generation service.

Wherein, the preset key generation service may be a key management system (Key Management Service, KMS) service, or other key generation services. The specific preset key generation service is not specifically limited in this application.

S102: Perform an encryption operation on the video to be encrypted by preset encryption algorithm and encryption key to obtain the encrypted video.

In S102, the preset encryption algorithm may be a 128-bit Advanced Encryption Standard (Advanced Encryption Standard, AES) algorithm, that is, an AES128 encryption algorithm, or other types of encryption algorithms. The determination of the preset encryption algorithm is set by technicians according to the actual situation, which is specifically limited in this application. The preset encryption algorithm of this application is preferably AES128 encryption algorithm.

Wherein, the encryption operation is an operation of encrypting the video segments obtained by converting the video to be encrypted; the video segments are obtained through transcoding operations and file segmentation operations; the video segments are used to represent multiple video streams.

The transcoding operation is used to convert the video to be encrypted into a preset index file in a unified format.

The file fragmentation operation is used to perform file fragmentation on the preset index file to obtain video fragments representing multiple video streams.

Specifically, the encryption operation is performed on the video to be encrypted through the preset encryption algorithm and encryption key, and the process of obtaining the encrypted video is shown in A1-A3.

A1: Convert the video to be encrypted into a preset index file; the preset index file is used to obtain its corresponding video network address to realize online playback.

Improve the difficulty of decrypting the encrypted video through the standard encryption algorithm, so as to prevent the video stream from being illegally intercepted and played, and improve the security of the encrypted video playback.

Then, the video decryption key is encrypted based on the public key.

In the embodiment of this application, since the public key is a dynamically generated public key, the video decryption key is encrypted each time through the public key, so that the encrypted video decryption key is different, and the security of encrypting the video decryption key is improved. .

Referring to Figure 2, it is another video processing method disclosed in the embodiment of the present application. The video processing method is applied to the client, and the video processing method mainly includes the following steps:

S201: Obtain the encrypted video and key interface sent by the server, wherein the encrypted video is obtained by the server using a preset encryption algorithm and encryption key to encrypt the video to be encrypted.

Among them, the key interface is obtained through the following B1-B2 methods.

B1: Obtain the preset index file corresponding to the encrypted video.

Wherein, the client sends the video unique identifier (videoId) and the user unique identifier (pin) to the video server, and the video server returns the m3u8 file address to the client, so that the client obtains the m3u8 file corresponding to the encrypted video through the m3u8 file address.

B2: Analyze the preset index file through the preset parsing method to obtain the key interface.

Wherein, the preset parsing method may be a regular matching parsing method, or other parsing methods. The determination of the preset analysis mode is set by a technician according to the actual situation, which is not specifically limited in this application. The default parsing method of this application is preferably a regular matching parsing method.

The encrypted file of the video segment is the above-mentioned .ts file.

The key interface for video decryption is the interface for converting the key in the URI field above into the server.

S202: Perform a decryption operation on the encrypted video to obtain a decrypted video stream for playing.

Wherein, the decryption operation is an operation of decrypting the video segment by calling the key interface and the pre-acquired video decryption key.

The key interface is used to realize that the video decryption key for each decryption operation is different.

The process of decryption operation is shown as C1-C3.

C1: Obtain the video decryption key corresponding to the encrypted video through the key interface, and the video decryption key is encrypted with the public key dynamically generated by the client.

The key interface returns the secret text of the video encryption key. Since the public key passed from the client to the server is dynamically generated each time, the secret text returned by the server to the client is different each time.

C2: Use the private key corresponding to the public key to decrypt the encrypted video decryption key to obtain the decrypted video decryption key.

Among them, the private key is used to decrypt the dynamically encrypted video decryption key through the client, and the decrypted video decryption key is obtained, so that the client can use the decrypted video decryption key to encrypt the encrypted files of the video fragments. Decrypt to get the decrypted video stream and play it.

The client uses the local private key to decrypt the secret text of the video encryption key to obtain the video decryption key.

C3: Decrypt the encrypted video through the decrypted video decryption key.

Wherein, the client uses the AES128 encryption algorithm and the video decryption key to dynamically decrypt the encrypted file of the video segment (that is, the .ts file) to obtain the video stream and play it.

For example, the server uses the public key to encrypt the video decryption key 123, which becomes the secret text ABCD after encryption, and returns the secret text ABCD to the client; the client uses the key to decrypt the secret text ABCD to obtain the video decryption key 123; Key 123 and AES128 encryption algorithm dynamically decrypt the file (that is, the .ts file) after dynamically decrypting the encrypted video segment, obtain the video stream and play it.
