Abstract:
A method for re-provisioning a user equipment (UE, 140) after a first digital security certificate for the UE (140) has expired includes communicating content data to a controller (130) over a first secure communication channel after verification of a validity of a first digital security certificate. Once it is realized the first digital security certificate has expired, the UE (140) sends a certificate provisioning request message over an unsecure channel to the controller (130) as a request to the controller (130) to provision a second digital security certificate. The UE (140) signs the certificate provisioning request message with the private key for the now expired first digital security certificate. A second digital security certificate is signed by the rescue-secret private key at the controller (130) and sent to the UE (140), which verifies its authenticity with the corresponding rescue-secret public key.
