摘要

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 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.
