An embodiment of a system for securing media content includes a digital media device comprising a memory associated with a secure element. The memory contains a private key and storage for at least one group key. The private key is used to decrypt transmissions from a remote access control system that are encrypted by a corresponding public key. The digital media device further comprises logic configured to respond to a first message received from the remote access control system encrypted by the public key and including a first group key, the logic responding to the first message by decrypting the first group key and storing the first group key in the memory of the secure element. The digital media device further comprises logic configured to decrypt a content key with the first group key. The content key is used to encrypt media content stored on a medium accessible by the digital media device.

Securing media content using interchangeable encryption key

A system including a controller and a pool of computing resources to run virtual machines are configured to automatically provision each virtual machine with unique cryptographic constructs. The controller receives a request to instantiate a virtual machine based on an image/template. The controller determines an authentication credential for a registration authority that the virtual machine will use. The controller determines the computing resources to run the virtual machine, and instructs the computing resources to boot the virtual machine. The controller passes the authentication credential to the virtual machine. After receiving the authentication credential, the virtual machine authenticates the registration authority and sends a request for the cryptographic constructs. The virtual machine securely receives the cryptographic constructs from the registration authority, enabling the virtual machine to securely communicate with other computing entities.
