摘要： A method and arrangement in a first mobile terminal (600) for determining allocation of radio resources for DMO communication amongst a group of mobile terminals. M the first mobile terminal, a first determining module 600a determines a communication (Sout, Sin) with a second mobile terminal (602) of the group. A second determining module (600b) determines a resource element (RE) for communication by applying a predefined cryptographic function Pbased on a terminal identification (K)). Tne cryptographic function has been configured in the mobile terminals of the group to provide terminal-specific resource elements for different mobile terminals within respective radio frames. A communication module (600c) then communicates with the second mobile terminal (602), either by transmission or reception of the data, on the determined resource element (RE).

摘要： The invention refers to monitoring usage of digital content provided from a content provider (30) over a network (40) to a client system (10). In the client system (10), a logging agent (150) generates and stores information concerning usage of the digital content individually for each usage to be monitored. The generated information is entered in a usage log (170; 175), either stored in the client system (10) or at a trusted party. The logged usage information is also authenticated allowing identification of the client using the associated digital content. The entries (172) of the log (170; 175) may include a representation (172-1) of the content, information about usage quality (172-2) and/or usage time (172-N). The logging agent (150) is preferably implemented in a portable tamper-resistant module (400), e.g. a network subscriber identity module. The module (400) may be pre-manufactured with the logging agent (150), or the agent (150) can be downloaded thereto.

摘要： In a procedure for delivering streaming media, a Client (1) first requests the media from an Order Server (3). The Order Server authenticates the Client and sends a ticket to the Client. Then, the Client sends the ticket to a Streaming Server (5). The Streaming Server checks theticket 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 receivesthe 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 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： Method and apparatus for supporting the forwarding of received data packets in a router (402,702) of a packet- switched network. A forwarding table (706a) is configured in the router based on aggregating router keys and associated aggregation related instructions received from a key manager (400,700). Each aggregating router key represents a set of destinations. When a data packet (P) is received comprising an ingress tag derived from a sender key or router key, the ingress tag is matched with entries in the forwarding table. An outgoing port is selected for the packet according to a found matching table entry that further comprises an associated aggregation related instruction. An egress tag is then created according to the aggregation related instruction, and the packet with the created egress tag attached is sent from the selected outgoing port to a next hop router.

摘要： A method and apparatus for establishing a cryptographic relationship between a first node and a second node in a communications network. The first node receives at least part of a cryptographic attribute of the second node, uses the received at least part of the cryptographic attribute to generate an identifier for the first node. The cryptographic attribute may a public key belonging to the second node, and the identifier may be a Cryptographically Generated IP address. The cryptographic relationship allows the second node to establish with a third node that it is entitled to act on behalf of the first node.

摘要： There is disclosed a method, and a communication system, and a communication node for implementing the claimed method, for attempting to enhance legitimacy assessment and thwart a man-in-the middle or similar false-location attack by evaluating the topology of a communication-session requesting node relative to the proposed communication path through a network between the requesting node and the requested node. Upon receiving the request,a PRD (Prefix Reachability Detection) protocol is initiated, either after or during a secure key exchange, if any, which if performed preferably includes an ART (address reachability text). The PRD is executed by sending a message to the communication node challenging the location-authenticity of the requesting device. The communication node, which may be for example an access router through which the requesting node accesses the network, determines if the requesting node is positioned behind the communication node topologically, and reports the result to the requested node. The requested node may then make a decision on whether to permit the communication. If so, the PRD may be repeated one or more times while the communication session is in progress.

摘要： An authentication method comprises providing a set of N plural number of master keys both to a user terminal (13) and to home network entity (11) and, when performing an authentication key agreement (AKA) transaction for an application, selecting one of the N number of master keys to serve as a master key for use both at the user terminal and the home network entity for deriving further keys for the application. For example, when performing an authentication key agreement (AKA) transaction for a first application, the method involves randomly selecting one of the N number of master keys to serve as a first master key for use both at the user terminal and the home network entity for deriving further keys for the first application; but when 10 performing an authentication key agreement (AKA) transaction for another application, the method involves randomly selecting another one of the N number of master keys to serve as master key for use both at the user terminal and the home network entity for deriving further keys for the another application.

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.
