Abstract
A client device includes a media player and a client proxy. The client proxy is to receive a first version of a playlist from a media server, the first version of the playlist including a first identifier of a cipher key to be used to decrypt at least one segment listed in the playlist. The first identifier identifies a location at the media server. The client proxy is to conduct a key exchange with the media server using the first location identifier to obtain the cipher key and store the cipher key at a local storage location at the client device. The client proxy also is to provide a second version of the playlist to the media player, the second version of the playlist including a second identifier of the cipher key, and the second identifier identifying the local storage location at the client device.
