Summary:Techniques for secure fast channel change in live content streaming are described. In some embodiments, during content preparation, a packager and/or an encoder encrypts media content items at both the service level (e.g., by encrypting a first portion of the plurality of segments with a service level access key unique to a service) and the channel level (e.g., by encrypting a second portion of the plurality of segments with a channel level access key unique to a channel associated with the service). On the receiving end, a client device (e.g., a media player) requests a service level access key prior to content acquisition. As such, a client can join any channel on a segment protected with the service level key without waiting for a license for that channel first, and the channel license can be acquired in parallel with the content acquisition during channel switching.
