Abstract
Various implementations include distributing DRM processing between a DRM key protection system and multiple receiving devices. To that end, a method includes receiving a first encrypted content key associated with a first receiving device, and receiving a second encrypted content key associated with a second receiving device. The method includes processing the first encrypted content key to generate a first decrypted content key, and processing the second encrypted content key to generate a second decrypted content key. The method includes generating a first protected content key based on the first decrypted content key, and generating a second protected content key based on the second decrypted content key. The method includes providing the first protected content key to the first receiving device, and providing the second protected content key to the second receiving device.
