    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: Before actually communicating information/data between two endpoints (C, S) connected to a network a secure and confidential distribution of a special key (K h) is performed to nodes (R j) along a path in the network. This is allowed by performing a path handshaking procedure in which first a hint token is forwarded along the path in a first direction and then a disclosure token is forwarded in the opposite direction. In forwarding the disclosure token it is verified in the nodes against the already received hint token. This assures that only nodes on the particular path will receive the special key or possibly some other information related thereto.

    摘要: Method and apparatus for controlling the routing of data packets in an IP network (200). A DNS system (202) stores a packet admission policy configured for a first end-host (B) that dictates conditions for allowing other end-hosts to get across data packets to the first end-host or not. A routing voucher is defined which is required for routing data packets to the first end-host. The routing voucher is distributed to routers (R) in the IP network. When an address query is received at the DNS system (202) from a second end-host, the voucher is supplied to the second end-host if the configured policy allows the second end-host to convey data packets. Otherwise, the voucher is not supplied. If allowed, the second end-host will add the routing voucher to any data packets directed to the first end-host. When a valid routing voucher is present in a packet at a router (204) in the network, the packet will be forwarded to the next router in the IP network. The router will otherwise discard the packet.

    摘要: A system and method for preventing unauthorized duplication of an identity module, IM, and authenticating valid IMs. Different information is stored in the IM and an authentication center, AuC, and if the information in the AuC is leaked, it is insufficient to clone the IM. The IM generates a first key, K1, and a second key, K2, while assuring that K1 cannot be derived from K2, and optionally that K2 cannot be derived from K1. The IM exports K2 and an identifier to the AuC while keeping K1 secret within the IM. During authentication, the IM provides to a third party such as a VLR, information containing the identifier. The VLR forwards the information to the AuC, which retrieves K2 based on the identifier and generates a first value, R, and a second value, X, based on at least K2. The AuC then returns R and X to the VLR, which forwards R to the IM. The IM then generates a response, RES, based on at least K1 and R, and sends the RES to the VLR. The VLR then verifies the RES based on X.

    摘要: When a mobile terminal (10), having a basic identity module (12) operative according to a first security standard, initiates a service access, the home network (30) determines whether the mobile terminal has an executable program (14) configured to interact with the basic identity module for emulating an identity module according to the second security standard. If it is concluded that the mobile terminal has such an executable program, a security algorithm is executed at the home network (30) to provide security data according to the second security standard. At least part of these security data are then transferred, transparently to a visited network (20), to the mobile terminal (10). On the mobile terminal side, the executable program (14) is executed for emulating an identity module according to the second security standard using at least part of the transferred security data as input. Preferably, the first security standard corresponds to a 2G standard, basically the GSM standard and the second security standard at least in part corresponds to a 3G standard such as the UMTS standard, and/or the IP Multimedia Sub-system (IMS) standard.

    摘要: The invention relates to digital rights management, and proposes the implementation of a DRM agent (125) into a tamper-resistant identity module (120) adapted for engagement with a client system (100), such as a mobile phone or a computer system. The DRM agent (125) is generally implemented with functionality for enabling usage, such as rendering or execution of protected digital content provided to the client system from a content provider In general, the DRM agent (125) includes functionality for cryptographic processing of DRM metadata associated with the digital content to be rendered. In a particularly advantageous realization, the DRM agent is implemented as an application in the application environment of the identity module. The DRM application can be preprogrammed into the application environment, or securely downloaded from a trusted party associated with the identity module. The invention also relates to a distributed DRM module, with communication between distributed DRM agents (125, 135) based on usage-device specific key information.
