摘要
A Master device (e.g., a SIM card) is configured with information regarding one or more Slave devices (e.g., SIM cards) that are associated with the Master device. The Master device is installed in a user device that receives content files and access and usage rights from a content provider. The Master device identifies one or more Slave devices that are associated with the Master device and transmits content files and the rights data to the Slave devices. A user device in which a Slave device is installed receives the content files and rights data sent by the Master device. The Slave device extracts a key from the rights data and provides the key to a decryption component of the user device, which uses the key to decrypt the content file.
