Abstract

A method and system to transport encrypted keys among the participants of a real time communications session are provided. The system may include a message detector, a carrier packet detector and a decrypting module. The message detector may be configured to receive, at a target device, a first communication from a source device. The first communication may comprise a first message. The carrier packet detector may be configured to receive, at a target device, a second communication from a source device. The second communication may comprise a first encrypted key to decode the first message. The decrypting module may be configured to decode the message, utilizing the first encrypted key.
