摘要： A method and apparatus to establish trust between two nodes in a communications network. A first node receives from a network node authentication data unique to the first node, which can be used to derive a compact representation of verification data for the first node. The first node also receives a certified compact representation of verification data of all nodes in the network. The first node derives trust information from the authentication data for the node, and sends to a second node a message that includes the trust information and part of the authentication data. The second node has its own copy of the certified compact representation of verification data of all nodes in the network, and verifies the authenticity of the message from the first node using the compact representation of verification data of all nodes in the network and the received trust information and authentication data.

摘要： The present invention relates to fraud prevention and authentication of a device to a user. The method of authenticating a personal device according to the invention comprises a set up sequence, wherein at least a first preferred output format is selected by the user, and a device configuration verification sequence. In the device configuration verification sequence a checksum is calculated and converted to a user friendly output format based on the user selected preferred output format. In addition the checksum may be calculated based on variable, and user selectable, keying material. The personal device, after being authenticated according to the above, may be used to authenticate a second device.

摘要： Devices for providing flexible control of rendering of protected media comprising first and second content objects are provided. An instruction database combines with traditional use of digital rights objects for determining, at rights parsing and instruction handler, conditions for rendering of first content object. Conditions may force the user to render second content objects or to input requested data and may adapt to environmental conditions exemplary relating to user profile, location, or time of day. A set of second content objects may be pre-determined and specified in provided instructions. User selection, from a list of second content objects, of a specified number of second content objects, provides for generation of a key enabling successful rendering of first content object.

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： A method for achieving a secure recording and storing of a recorded activity is based on an extended Digital Rights Management (DRM) system. A recording and storing procedure is initiated, in response to recognising one or more triggers at a device hosted by a user equipment. On the basis of the one or more triggers a Rights Issuer is located, and a Recording and Storing Instruction (RSI) is retrieved from the RI, using an existing DRM standard. Based on the RSI, a trusted storage for storing the recorded activity is located, and one or more recording procedures, involving one or more recording equipments, are activated and managed by the device. Before the recorded content is forwarded to the trusted storage, a protected content is generated from the recorded content, according to content of the RSI.
