摘要:
A communication system 100 includes a group of user devices, a first device separate from the group of user devices, a first satellite, a peer-to-peer network 130 in communication with the user devices and the satellite 106 and a content delivery network 120 in communication with the user devices. The content delivery network encrypts the content in response to a first encryption-decryption information and communicates the content to the plurality of user devices through a satellite. At each of the plurality of the group of user devices the content is encrypted in response to a second encryption-decryption information. A first user device communicates a content request to the group of user devices. At least one of the group of user devices communicates the content to the first user device through the peer-to-peer network. The first user device requests the encryption-decryption information from a content delivery network through a terrestrial network. The content delivery network 120 communicates the encryption-decryption information to the first user device through the terrestrial network. The first user device decrypts the content in response to the encryption-decryption information.
