Abstract: A processing device of a media server selects a media item to be provided to users via a satellite broadcast system, encrypts the media item using an encryption key to generate an encrypted media item, and transmits the encrypted media item to the satellite broadcast system via a first communication protocol. The processing device receives a request from a user device for authorization to decrypt the encrypted media item obtained by the user device via a direct connection with the satellite broadcast system. The request is received by the media server via a second communication protocol that is different from the first communication protocol. The processing device determines whether the user device is authorized to decrypt the encrypted media item, and transmits a key for decrypting the encrypted media item in response to the user device being authorized to decrypt the encrypted media item.

Abstract: Implementations disclose an access control mechanism for peer-to-peer sharing technology. A method includes receiving, by a processing device of a first user device, an encrypted media item and a wrapped encryption key from a second user device via a peer-to-peer connection; transmitting, by the first user device, the wrapped encryption key and a request to a media server to determine whether the first user device is authorized to play the encrypted media item; receiving, from the media server, a response indicating the first user device is authorized to play the encrypted media item, the response comprising an encryption key derived from the wrapped encryption key; and decrypting the encrypted media item using the encryption key to play the media item.
