description A method is provided for managing key rotation (use of series of keys) and secure key distribution in over-the-top content delivery. The method provided supports supplying a first content encryption key to a content packaging engine for encryption of a first portion of a video stream. Once the first content encryption key has expired, a second content encryption key is provided to the content packaging engine for encryption of a second portion of a video stream. The method further provides for notification of client devices of imminent key changes, as well as support for secure retrieval of new keys by client devices. A system is also specified for implementing a client and server infrastructure in accordance with the provisions of the method.
