摘要： A method and apparatus for key management in a communication network. A Key Management Server (KMS) receives from a first device a request for a token associated with a user identity, the user identity being associated with a second device. The KMS then sends the requested token and a user key associated with the user to the first device. The KMS subsequently receives the token from the second device. A second device key is generated using the user key and a modifying parameter associated with the second device. The modifying parameter is available to the first device for generating the second device key. The second device key is then sent from the KMS to the second device. The second device key can be used by the second device to authenticate itself to the first device, or for the first device to secure communications to the second device.

摘要： When setting up communication from a user equipment UE (1), such as for providing IP access for the UE in order to allow it to use some service, information or an indication of at least one network properly relating to a first network, e.g. the current access network (3, 3′), is sent to the UE from a node (13) in a second network such as the home network (5) of the subscriber ask UE. The information or indication can be sent in a first stage of an authentication procedure being part of the setting up of a connection from the UE. In particular, the network property can indicate whether the access network (3, 3′) is trusted or not.

摘要： A method (700) for use in a cellular system (100), comprising the step of transmitting a predefined message (705) comprising a primary warning notification (710) and verification information (715) related to the primary warning notification to user terminals in one or more cells of the system. The predefined message is transmitted simultaneously to a plurality of user terminals (740) in the system (100) on a physical channel (745) in the system which is dedicated to messages to single users. Suitably, the physical channel used is a paging channel (750) in the system (100), and also suitably, the predefined message causes the user terminals to listen (720) for a secondary warning notification in subsequent messages on the same channel.

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 communication method for making computer implemented man-in-the-middle (MITM) costly to succeed. Advantageously, the method does not require secure/trusted network servers. The method utilizes a test (e.g., an obscured pin value) to enable a first human user of a communication device to have a level of confidence that the first user is communicating directly with a second human user, as opposed to communicating with a machine that is pretending to be the second user.

摘要： A Feedback Shift-Register (FSR) (400) enabling improved testing, in particular Built-In Self-Tests (BIST), is provided. Each cell (401) of the FSR may either be an observable cell, associated with a non-trivial feedback function (402) implemented by a combinational logic circuit, or a controllable cell, having an associated state variable which belongs to the dependence set of exactly one of the non-trivial feedback functions. Each controllable cell(420)is provided with a multiplexer (423) for selecting either a predecessor cell of the controllable cell or a test value as input. As a result, the sequential circuit of the FSR may be tested using tests for combinational logic. The disclosed test procedures utilize a minimal set of test vectors and allow detection of all single stuck-at faults in the FSR. The proposed modifications do not increase the propagation delay of the original design, and the resulting dynamic power dissipation during test is considerably less than that of known BIST designs.
摘要翻译：提供了反馈移位寄存器（FSR）（400），可实现改进的测试，特别是内置自检（BIST）。 FSR的每个小区（401）可以是与由组合逻辑电路实现的非平凡的反馈功能（402）相关联的可观察小区，或者是具有相关联的状态变量的可控单元，正是其中一个非平凡的反馈功能。每个可控单元（420）设置有用于选择可控单元的前导单元或测试值作为输入的多路复用器（423）。因此，可以使用组合逻辑的测试来测试FSR的顺序电路。所公开的测试程序使用最小的一组测试向量，并允许检测FSR中的所有单个卡住故障。所提出的修改不会增加原始设计的传播延迟，并且在测试期间产生的动态功耗明显小于已知的BIST设计。

摘要： A method of securing a session between a Network Application Function, NAF, and a User Equipment, UE, connected to a network. The NAF is assigned a NAF identifier, NAF_id, using the Generic Bootstrapping Architecture, GBA, or a similar architecture and a shared secret is established between the UE and the NAF (S7.1). An application request containing a bootstrapping transaction identifier is sent to the NAF from the UE (S7.2) and an authentication request comprising the bootstrapping transaction identifier, the NAF_id, and information derived from the shared secret is sent to a Bootstrapping Server Function, BSF, from the NAF (S7.4).The BSF and the UE determine a NAF key, Ks_NAF, by using a modified parameter in place of or in addition to an original parameter in a key derivation function, the modified parameter being derived from the shared secret and the original parameter of the key derivation function (S7.5). This NAF key is transmitted from the BSF to the NAF (S7.6) and used to secure communications between the NAF and the UE (S7.7). Also provided are apparatus to act as a NAF, UE, and BSF in the method above.

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.
