摘要： A basic idea according to the invention is to enhance or update the basic cryptographic security algorithms by an algorithm-specific modification of the security key information generated in the normal key agreement procedure of the mobile communication system. For communication with the mobile terminal, the network side normally selects an enhanced version of one of the basic cryptographic security algorithms supported by the mobile, and transmits information representative of the selected algorithm to the mobile terminal. The basic security key resulting from the key agreement procedure (AKA, 10) between the mobile terminal and the network is then modified (22) in dependence on the selected algorithm to generate an algorithm-specific security key. The basic security algorithm (24) is then applied with this algorithm-specific security key as key input to enhance security for protected communication in the mobile communications network.

摘要： A solution making it possible for one telecommunication network operator (10′) to act as intermediate distributor or administrator of a content provider (60) for a multitude of operators (20) is presented. The content provider (60) has a single relation to the central operator (10′), in turn having relations to other operators (20). It is thus possible for the content provider (60) to reach all users (30) of all operators (10′, 20) through a single relation to that operator (10′). The content provider (60) provides service content, e.g. media content. A list of targeted users (30) or subscribers is compiled. The central operator (10′) collects necessary subscriber attributes (80), such as position, device information and access properties, from the other operators (20). The content is modified according to the collected attributes (80), and the content is distributed to the subscribers (30) in the best possible way.

摘要： A method for establishing a security association between a client and a service node for the purpose of pushing information from the service node to the client, where the client and a key server share a base secret. The method comprises sending a request for generation and provision of a service key from the service node to a key server, the request identifying the client and the service node, generating a service key at the key server using the identities of the client and the service node, the base secret, and additional information, and sending the service key to the service node together with said additional information, forwarding said additional information from the service node to the client, and at the client, generating said service key using the received additional information and the base key. A similar approach may be used to provide p2p key management.

摘要： An encrypted/authenticated mobile application part (MAP) protocol message is sent between a first network element (42A) of a first telecommunications network (40A) and a second network element (42B) of a second telecommunications network (40B). The first network element uses a master security association to derive a connection-specific security association, and includes in the encrypted/authenticated MAP message a parameter obtained from the connection-specific security association. Upon receipt at the second network element, the master security association is used to derive a connection-specific security association for use by the second network element. The second network element uses the connection-specific security association to decrypt/decode the MAP message.

摘要： A method is described herein for protecting multicast/broadcast traffic (e.g., mobile TV, multimedia) which is transmitted from a broadcast service provider via a mobile operator to one or more mobile devices. To protect the multicast/broadcast traffic, the method utilizes a broadcast key distribution and encryption architecture that is based in part on the existing GSM/UMTS authentication standards.

摘要： The disclosure relates to a gyroscope in which an electric signal corresponding to an angle (-.alpha., +.alpha.) between the rotor of the gyroscope and the frame of the rotor is generated. The rotor is provided with one or more permanent magnets. An element of magnetic material is disposed in the frame of the rotor so that the latter may move in relation to the element during its rotation. The element may be passed by the magnetic fields of the permanent magnets during rotation of the rotor so that magnetic flux changes occur in the element. The element is arranged such that the flux changes are dependent upon the above-mentioned angle and the flux changes are sensed by an electric induction winding which generates the electric signal.
