Abstract
A method and apparatus for sending a first secured media stream having a payload via an intermediate node. The intermediate node receives from a sender the first secured media stream. An end-to-end context identifier and a hop-by-hop context identifier are determined for the first secured media stream, where the hop-by-hop context identifier relates to the intermediate node and the end-to-end identifier relates to the sender. A second secured media stream is generated, which includes at least the payload of the first secured media stream and the context identifiers to identify the first secured media stream. The second secured media stream is sent to a receiving node, and the context identifiers are also sent to the receiving node. The context identifiers are usable by the receiving node to recover the first secured media stream.
