This paper describes a secure Pay TV protocol based on a public-key distributed encryption scheme that enables the Pay TV broadcaster to robustly add or remove any subscriber without changing private decryption keys of other subscribers. In other words, the updating process is transparent to the subscribers. This feature exhibits a distinct advantage over a symmetric key based system where all subscribers share a single key and therefore it is impossible to dynamically remove a subscriber from the system.
