摘要： A Feedback Shift-Register (FSR) enabling improved testing, e.g., Built-In Self-Tests (BIST), is provided. Each cell of the FSR may either be an observable cell, associated with a non-trivial feedback function 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 is provided with a multiplexer for selecting either a predecessor cell of the controllable cell or a test value as input. Thus, the sequential circuit of the FSR in an embodiment is 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 resulting dynamic power dissipation during test can be considerably less than known BIST designs.

摘要： A method, computer program and a server node (100) in a communications network (50) for reduction of undesired energy consumption of the server node (100), the method comprising: receiving a request message from a client (120), the request message containing message fields comprising at least a message ID field and an integrity indication field containing a first integrity indication, determining a relation key by performing a calculation by usage of a master key commonly known by the server node (100) and an authorization engine (110) and at least data comprised in the message ID field, calculating a second integrity indication based on a subset of the message fields by usage of the relation key, wherein the subset excludes at least one message field that is predictable by a trusted client (120), verifying the subset of the message fields by comparing the first and second integrity indications, and determining the message to be authorized when the comparison indicates equality, and wherein when the message is not authorized, suppressing reception of the message.

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 (202) at a device (201) hosted by a user equipment (200a, 200b). On the basis of the one or more triggers a Rights Issuer (204,RI) 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 (2:5) by the device. Before the recorded content is forwarded (2:6) to the trusted storage, a protected content is generated from the recorded content, according to content of the RSI.

摘要： The present invention relates to an arrangement, system and method for managing rights to streaming media using a management mechanism based on a content object and a rights object. In accordance with the invention the content object comprises means for initiation of the streaming media and the rights object comprises usage rules defining the rights to use said streaming media. The invention also relates to a method of delivering and protecting digital streaming media. The initiation may comprise a session description of the streaming media, a SDP description, a URL to said streaming media or a SMIL file. Preview and super-distribution are provided. The content object is delivered like a downloadable object in a rights management system for download, thereby reusing the mechanisms for rights management of said latter system for rights management in a system for transmission of streaming media.
