Abstract: A method for registering a device in a wireless network comprising a central controller. The method includes the step of asking a user whether he wants to install a new network or install a device on the network. In the case of installing a new network, the user enters a PIN code, an authentication key of the new network is generated and the device becomes the central controller. In the case of installing the device on an existing network, the user enters a PIN code, and upon authorization, receives an authentication key of the network for use in authenticating procedures with the central controller.

Abstract: The invention relates to a method whereby it can be checked whether data received by a receiver has been sent by a transmitter authorized by a trusted third party, the transmitter and the receiver being connected to a digital network. An identifier is associated with the data sent by the transmitter and, on receipt of the data by the receiver, the receiver generates a random number and diffuses the same on the network. The transmitter that receives said random number calculates a response by applying a first function to the random number and to the identifier, and sends said response to the receiver which verifies the response received by applying a second function to the response received, the random number and the identifier. The first function is delivered first to the transmitter by the trusted third part, and the second function is a function for checking the result of the first function which is delivered first to the receiver by the thrusted third party.

Abstract: A method for discovering emulated clients. A verifier sends a cryptographic challenge C to a client and preferably starts a timer. The client uses a deterministic key search algorithm to find the correct key and returns the result as a number of tries needed. The verifier then stops the timer if this was started and verifies that the result is correct and preferably that the response was timely. Also provided is a verifier.

Abstract: The number of devices installed in an Authorized Domain is controlled by a master device functionality. This master devices stores ceiling values for the total number Totaljimit of devices to be installed in the AD; the total number Localjimit of devices to be installed in a local proximity with the master device and the total number Remotejimit of devices to be installed remotely from said master device. The master device also stores current values of the number Local_count of devices installed in the AD in local proximity with the master device; and the number Remote_count of devices installed in the AD remotely from said master device. When a new device is to be installed in the AD, the ceiling values are checked with respect to the current values and it is checked whether the device is in local proximity with the master device to authorize or not its installation in the AD, either locally or remotely.

Abstract: A method for service delivery to a client, in which the client selects a service, and establishes a connection with a system server to which it sends an identity associated with the client and an identifier of the service. The system server verifies that the client is authorized to access to the service and that the client is non-emulated. If this is verified, the service is provided to the client. In a preferred embodiment, the service is scrambled content and the system server provides a descrambling key to the client, and instructs a content server to provide the scrambled content to the client. Also claimed are a device, a system, and a system server.

Abstract: A secure pre-recorded medium and a method for descrambling encrypted content thereon. When a player wants to access the content, a secure processor on the medium verifies that the player has not been revoked, preferably by comparing an identity of the player with identities in a revocation list, after which a mutual authentication is performed. The secure processor then verifies that the player has the rights to access the content and provides the player with the key necessary to descramble the content, whereafter the player descrambles the content.
