Abstract
A method for securely receiving a multimedia content by a client device operated by one or more operator(s) involving a dedicated provisioning server of a security provider managing symmetric secrets used by the client devices and operators license servers. The provisioning server provides to the client device one or more generations of operator specific unique device secrets, which are then exploited by the various operators' license servers to deliver licenses such that authorized client devices can consume protected multimedia contents.
