Abstract
A system and a method for secure transmission of protected content to a subscriber, without requiring a smart card or other renewable security element to be in physical proximity of the recipient module of the subscriber, such as a set-top box for example. Therefore, the renewable security element may optionally be protected and controlled by the transmitter of the protected content, such as by the broadcaster for example.
