Abstract: Pairing is achieved between a host communications device and a peripheral communications device, in order to establish an ad hoc wireless or wired network. A device identification, relating uniquely to the peripheral device, is displayed on the host device. In order to accept the pairing, the user confirms that the device identification displayed on the host device matches that printed on the peripheral device, and then completes the pairing procedure by pressing a key on the peripheral device, or, if Near Field Communication (NFC) techniques are implemented in the devices, by placing the peripheral device in contact with, or sufficiently close to, the host device. Thus, secure pairing is achieved, without requiring a complex user interface on the peripheral device.

Abstract: An electronic component is provided having a plurality of functionalities. The electronic component comprises a control logic, and a non-volatile storage element. The control logic is coupled to the non-volatile storage element and is adapted for storing values in the non-volatile storage element based on an external input signal to the electronic component, each value being indicative for one or more functionalities of the plurality of functionalities. The control logic is adapted for controlling the availability of the plurality of functionalities based on one or more values stored in the non-volatile storage element and for outputting a confirmation signal being indicative for the availability of the plurality of functionalities.

Abstract: The present invention relates to a method for watermarking a processing module. The processing module is designed to process an electronic signal and form a processed signal involving steps of applying a first functional operator to cause a significant alteration to the processed signal. The first operator is embedded in the processing module. Additionally, a second functional operator is provided to co-operate with the first operator-so the alteration is essentially cancelled. The second operator-is adapted to act as an extractable identifier serving as a watermark for the processing module. An advantage with the method is the fact that since the first and the second operators are implemented as functional processing blocks, conventional debugging tools cannot be used to attack the processing module.
