1. An apparatus of a client device operable to perform uniform resource indicator (URI) authentication for dynamic adaptive streaming over hypertext transfer protocol (HTTP) (DASH), the apparatus comprising:
memory; and
one or more hardware processors configured to:
decode a media presentation description (MPD) file received from a server in a content delivery network (CDN), wherein the MPD file includes:
a URI, a URI signature associated with the URI, and a URI key indicator associated with the URI, wherein the URI key indicator is used to generate the URI signature;
store the MPD file in the memory; and
authenticate by the client device the URI included in the MPD file using the URI signature and the URI key indicator included in the MPD file for requesting from the server a DASH segment.
