摘要： A method of establishing keys for at least partially securing media plane data exchanged between first and second end users via respective first and second media plane network nodes. The method comprises sending session set-up signalling from said first end point towards said second end point, said session set-up signalling including a session key generated by said first end point. The set-up signalling is intercepted at a first signalling plane network node and a determination made as to whether or not a signalling plane key has already been established for securing the signalling plane between said first end point and said first signalling plane network node. If a signalling plane key has already been established, then a media plane key is derived from that signalling plane key, and the media plane key sent to said first media plane network node for securing the media plane between said first end user and said first media plane network node. If a signalling plane key has not already been established, then an alternative media plane key is derived from said session key and sent to said first media plane network node for securing the media plane between said first end user and said first media plane network node.

摘要： A method and arrangement is disclosed for managing session keys for secure communication between a first and at least a second user device in a communications network. The method is characterized being independent of what type of credential each user device implements for security operations. A first user receives from a first key management server keying information and a voucher and generates a first session key. The voucher is forwarded to at least a responding user device that, with support from a second key management server communicating with the first key management server, resolves the voucher and determines a second session keys. First and second session keys are, thereafter, used for secure communication. In one embodiment the communication traverses an intermediary whereby first and second session keys protect communication with respective leg to intermediary.

摘要： 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.
