    摘要: A system comprising an IMS network (104), an adapter module (106), an identity provider (108) and an application (110) is described. The adapter module (106) is within an IMS trust domain. The application (110) is within the trust domain of the identity provider. A user of the system can access the application (110) via the IMS network (104), regardless of whether the application is within the IMS trust domain, by making use of the adapter module (106) to obtain the user's user credentials for the application from the identity provider.

    摘要: An access specific key is provided for securing of a data transfer between a mobile terminal and a node of an access net. For authentication of the mobile terminal, a authentication server generates a session key, from which a basic key is derived and transferred to an interworking-proxy-server. The interworking-proxy-server derives the access specific key from the transferred basis key and provides the key to the node of the access net.

    摘要: The method for the transmission of media data from a multicast service by a first apparatus to a plurality of second apparatuses is suitable for preventing reception of the media data by an unauthorized second apparatus using a security process. A first apparatus is provided which can be used to provide the media data protected by a security process. A third apparatus is provided which can be used to perform the security process with the first apparatus, performance of the security process between the first apparatus and the third apparatus and, on the basis of this, interchange of at least security data between the first apparatus and the third apparatus in order to provide the media data. A second apparatus is selected which can be used to perform at least one reception process for receiving the media data. A first data transmission link is selected which can be used to couple the first apparatus and the second apparatus at least for the purpose of transmitting the media data. The provided media data is received using the second apparatus via the first data transmission link.

    摘要: Cryptographic material is generated for a protocol for the encrypted transmission of media data between a subscriber device and a provider device. A first symmetric key of the subscriber device and the provider device is inserted in a symmetric key protection mechanism of a network protocol of a control layer to establish a communication session between the subscriber device and the provider device. A first time-variable parameter is transmitted from the provider device to the subscriber device. A second symmetric key for protecting the key management protocol is calculated by both the provider device and the subscriber device using a defined function depending at least on the first symmetric key and the first time-variable parameter.

    摘要: A method, apparatus and computer program product are provided to provide fresh security context during intersystem mobility. A method is provided which includes receiving an indication of handover of a remote device from a source system to a target system. The target system may implement a communications standard different from that of the source system. The method also includes determining a current sequence number value of a security context maintained in the source system. The method additionally includes deriving a fresh mapped security context for the target system based at least in part upon the determined sequence number value. The method further includes providing the derived fresh mapped security context to the target system.

    摘要: The method provides that a session code (K) can be agreed between a first computer unit (U) and a second computer unit (N), without it being possible for any unauthorized third party to gain access to useful information relating to the codes or the identity of the first computer unit (U). This is achieved by embedding the principle of the El-Gamal code interchange in the method, with additional formation of a digital signature via a hash value of the session code (K) which is formed by the first computer unit (U).

    摘要: Cryptographic network separation functionality is provided on a user device. An option to store information about a type of database where a user is homed is provided in an indicator on a storage medium. An interface is provided between the user device and the storage medium for accessing the indicator. In case the information about the type of database cannot be obtained from the storage medium, it is determined not to enforce the cryptographic network separation functionality on the user device.
