The excitation of processing paths in a microelectronic circuit is organized by providing one or more pieces of input information to a decision-making software, and executing the decision-making software to decide, whether one or more of said processing paths of the microelectronic circuit are to be excited with test signals. Deciding that said processing paths are to be excited with said test signals results in proceeding to excite said one or more of said processing paths with said test signals and monitoring whether timing events occur on such one or more excited processing paths. A timing event is a change in a digital value at an input of a respective register circuit on an excited processing path, which change took place later than an allowable time limit defined by a triggering signal to said respective register circuit.

Method, arrangement, and computer program product for organizing the excitation of processing paths for testing a microelectric circuit

A method of modifying a digital rights object including a first portion including a first key and a second portion including first control information for controlling the rights to content encrypted with a second key, the method including the steps of: a) calculating a first function from the first control information of the digital rights object; b) operating on the first key using the first function calculated in step a), to obtain the second key; c) modifying the first control information of the second portion to second control information; d) calculating a second function from the second control information of the digital rights object; and e) operating on the second key obtained in step b) using the second function calculated in step d), to obtain a third key for replacing the first key.

Enabling modification of control information, which controls the rights to content, where access to a key for decrypting the content requires a particular value that becomes modified when the control information is modified

A method and apparatus for activating protected content on a portable memory device when the portable memory device is incorporated into a mobile terminal during the manufacture of the mobile terminal. During manufacturing, the portable memory device is coupled to the mobile terminal, and the mobile terminal is powered on. An activation program resident on the mobile terminal is executed upon power on of the mobile terminal. The activation program imports a secure rights database of rights files from the portable memory device, activates an active rights database resident on the mobile terminal based on the imported secure rights database, and disables the secure rights database on the portable memory device to prevent subsequent unauthorized use of the portable memory device.

Secure content activation during manufacture of mobile communication devices

A method and apparatus are provided for personalizing content on a mobile phone, device or terminal, as any other type of user equipment, instead of the personalization being performed by a network infrastructure device such as a voucher server. The mobile phone, device or terminal has a voucher-driven on-device content personalization module for personalizing the content based on information contained in a rights expression voucher that accompanies the content. The mobile phone, device or terminal personalizes the content without server-side support from the wireless network infrastructure. The rights expression voucher contains information that controls the content personalization in the device. When the device or terminal receives content with this kind of rights expression voucher, it starts personalization operation according to personalization information. This personalization operation can personalize content to the same 'individuals' as the server-based personalization. In addition, the device-based personalization operation can use personalization information not known by the voucher server (for example, device specific hardware operations). The personalization can be made by the local encryption of the content encryption key.

Voucher driven on-device content personalization

A system, apparatus, and method for facilitating OTA activation of protected content pre-programmed on a memory device that is operable on mobile terminals. A removable memory device is provided for coupling to the mobile terminal, where the removable memory device is pre-programmed with secure content and a secure rights database of rights files. OTA activation is performed to activate the secure content stored on the removable memory device in response to an attempt to access the secure content. The removable memory device is altered to prohibit further access to the secure rights database after the database is imported to the mobile terminal. Access to the secure content is enabled as dictated by corresponding rights files when the OTA activation has successfully completed.
