    摘要: Methods and arrangements for supporting a forwarding process in routers when routing data packets through a packet-switched network, by employing hierarchical parameters in which the hops of a predetermined transmission path between a sender and a receiver are encoded. A name server generates and distributes router-associated keys to routers in the network which keys are used for computing the hierarchical parameters.

    摘要: According to an aspect of the present invention there is provided a method of operating a communication device, the communication device being part of a group comprising two or more communication devices that share a subscription to a communication network. The method comprises receiving a group authentication challenge from the network, at least part of the group authentication challenge having been generated using group authentication information that is associated with the shared subscription. The device then generates a device specific response to the group authentication challenge using the group authentication information and device specific authentication information and sends the device specific response to the network. The device is for example a member of a machine-type communication device group.

    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 an arrangement for providing keys for protecting communication between a terminal (300) and service points in a communication network. A basic key (Ik) is first established with a service control node (304) when the terminal has entered the network. An initial modified key (Ik1) is then created in both the service control node and the terminal, by applying a predetermined first function (f) to at least the basic key and an initial value of a key version parameter (v). The initial modified key is sent to a first service point (302), such that it can be used to protect communication between the terminal and the first service point. When the terminal switches to a second service point (306), the first service point and the terminal both create a second modified key (Ik2) by applying a predetermined second function (g) to the initial modified key, and the first service point sends the second modified key to the second service point.

    摘要: In a procedure for delivering streaming media, a Client first requests the media from an Order Server. The Order Server authenticates the Client and sends a ticket to the Client. Then, the Client sends the ticket to a Streaming Server. The Streaming Server checks the ticket for validity and if found valid encrypts the streaming data using a standardized real-time protocol such as the SRTP and transmits the encrypted data to the Client. The Client receives the data and decrypts them. Copyrighted material adapted to streaming can be securely delivered to the Client. The robust protocol used is very well suited for in particular wireless clients and similar devices having a low capacity such as cellular telephones and PDAs.

    摘要: A path switch message in a mobile radio access network is protected as the message is sent over a user plane interface that may be insecure (e.g. lacks integrity and/or confidentiality protection). According to the invention a UE provides an AP with a fresh integrity key over an already existing and secure RAN channel enabling AP to use the integrity key to integrity protect information sent to a UPN. Specifically, UE derives locally at least a user plane key K1. The key derivation is done at authentication e.g. when performing an AKA procedure. On the network side CPN derives the same key K1 for delivery to UPN. At handover, the UE generates a fresh integrity key K3 by applying a Key Derivation Function (KDF) with at least the UP key K1 and a nonce, e.g. a sequence number.
