ABSTRACT:
A method for securely streaming real-time content from a caching server to an authorized client. The method includes the steps of encrypting an RTSP (real-time streaming protocol) message having a header and a payload, the RTSP message being encrypted in its entirety; and providing a first clear header for the encrypted RTSP message. Further, the method includes the steps of encrypting an RTCP (real-time control protocol) message having a header and a payload, the RTCP message being encrypted in its entirety; and providing a second clear header for the encrypted RTCP message. Thereafter, the encrypted RTSP message and the first clear header are transmitted, and the encrypted RTCP message and the second clear header are transmitted in order to securely stream the real-time content from the caching server to the authorized client.
