摘要： There is described herein a device (101) for communicating with a network. The device (101) comprises a communications unit for receiving data, a notification device for providing a notification to a user, and a control unit for controlling the operation of the communications unit and notification unit. The communications unit is configured to receive an information message (110, 112, 115), and to receive security authentication data (110, 112, 115) associated with the information message if such security authentication data is available. The control unit is configured to operate in a first or second configuration. In the first configuration it ignores the security authentication data, (111, 113), and instructs the notification unit to convey the notification to the user. In the second configuration, it verifies the information message (116) on the basis of the security authentication data and instructs the notification unit to convey the notification to the user if the verification is successful. The communications unit is configured to receive a configuration message (114) indicating the configuration in which the control unit should operate, and the control unit is configured to change configuration if the indicated configuration is different to the current configuration.

摘要： A method and arrangement for distributing a security policy to a communication terminal having an association with a home communication network, but being present in a visited communication network. The home communication network (106) generates its own preferred security policy Ph and the visited communication network (102) generates its own preferred security policy Pv. A communication network entity (104) in the visited communication network combines the security policies and selects security algorithms/functions to apply from the combined security policy. By generating a security policy vectors of both networks and combine them before the security algorithms are selected, enables both networks to influence the selection without affecting use of existing signalling messages.

摘要： The present invention relates to methods and devices for detecting persistency of a first network node (12). In a first aspect of the invention, a method is provided comprising the steps of monitoring (S101), during a specified observation period, whether the first network node has established a connection to a second network node (13), and determining (S102) a total number of sessions of connectivity occurring during said specified observation period in which the first network node connects to the second network node. Further, the method comprises the steps of determining (S103), from the total number of sessions, a number of sessions comprising at least one communication flow between the first network node and the second network node, and determining (S104) inter-session persistence of the first network node on the basis of the total number of sessions and the number of sessions comprising at least one communication flow.

摘要： Method and arrangement in a mediating function (204) for supporting detection of fraud in a network, when a network security function (200) is employed for analyzing activities in the network in view of predefined alert criteria, and a fraud detection function (202) is employed for analyzing e.g. charging information of users. When a first alert is received from a first one of the network security function and the fraud detection function, indicating that the predefined alert criteria of said first function have been satisfied, the alert criteria of the second one of said network security function and fraud detection function are modified based on the received first alert. Thereby, the network security and fraud detection functions can be correlated and made more efficient regarding accuracy and/or speed in detecting fraud.

摘要： Methods and arrangements for enabling the use of a first device (300) for controlling transfer of media content from a content provider (306) to a second device (302). The first device has a pre-established security association with the communications network. When the network detects a request made by the first device for delivery of media content to the second device, key information is established which enables determination of one or more media keys for encryption of the media content. The network sends key information to the content provider and to the first device. The content provider then delivers media content encrypted by the media key(s) to the second device. Further, the first device forward the media key(s) over a local communication link to the second device for decryption of media content encrypted by the media key(s) when delivered by the content provider.
