Abstract

Systems and methods securely provide media content from a media server to a media client via a network. The media content is segmented to create multiple media segments that are each identified in a playlist, and at least one of the media segments is encrypted using a cryptographic key. The cryptographic key is also identified in the playlist, and the playlist is provided from the media server to the media client via the network. The various media segments and cryptographic keys may then be requested from and provided by the media server using hypertext transport protocol (HTTP) or similar constructs to allow the media client to receive and decrypt the various segments of the media content.
