A current version certificate is stored that includes a corresponding current version identifier. A current instance certificate is received from the certificate authority, wherein the current instance certificate includes the current version identifier of the current version certificate and a current instance public key corresponding to the current instance private key. The current instance certificate is sent to a local station, during a registration with the local station. A request for video content is generated and sent to the local station. First encrypted data is received from the local station, wherein the first encrypted data includes a content key that is encrypted via the current instance public key. Second encrypted data is received from the local station, wherein the second encrypted data includes the video content that is encrypted via the content key.
