<p>Method and apparatus for encrypting a media stream sent from a server (2) via an encryption proxy (3) to a client (4), connected to the encryption proxy (3) over a network (7), where packets of the media stream are either statically encrypted by a pre-processor (1) or dynamically encrypted by the encryption proxy (3). The pre-processor (1) selects which packets of the media stream that are to be statically encrypted and which packets that are to be dynamically encrypted as defined in an encryption scheme (5).</p> |
