摘要：
A server receives a video content identifier and a video player identifier from a video player through a network. The video content identifier identifies video content. The video player identifier identifies a video player. Further, the video player identifier is provided to a hash generator to generate a hash of the video player. In addition, the plaintext of the video content is encrypted with the encryption key to generate ciphertext. The encryption key is encrypted with the hash to generate an encrypted encryption key.
