Abstract: Ein eingebettetes Sicherheitsmodul (102) enthält einen Sicherheitsprozessor (122), einen flüchtigen und nichtflüchtigen Speicher und eine Schnittstelle (116). Der Sicherheitsprozessor (122) enthält Transistoren, die in einer oder mehreren Halbleiterschichten eines Halbleiter-Die ausgebildet sind, und implementiert eine oder mehrere sicherheitsrelevante Funktionen an Daten und/oder Code, auf die der Sicherheitsprozessor (122) zugreift. Der flüchtige Speicher wird auf dem gleichen Halbleiter-Die wie der Sicherheitsprozessor (122) hergestellt und speichert die Daten und/oder den Code, auf die der Sicherheitsprozessor (122) zugreift. Der nichtflüchtige Speicher enthält nichtflüchtige Speicherzellen, die über jeder Halbleiterschicht des Halbleiter-Die angeordnet sind, und speichert die Daten und/oder den Code sicher, auf die der Sicherheitsprozessor (122) zugreift, und Sicherheitsinformationen bezüglich der Daten und/oder des Codes, auf die der Sicherheitsprozessor (122) zugreift. Die Schnittstelle (116) wird auf dem gleichen Halbleiter-Die wie der Sicherheitsprozessor (122) hergestellt und liefert eine Kommunikationsschnittstelle (116) für den Sicherheitsprozessor (122).

Abstract: Apparatus for contactless data transmission according to a predetermined transmission protocol providing control information and payload for a data transmission, with a near field communicator and an interface connected to the near field communicator, the interface being operative to exchange, using a first protocol, data with the near field communicator for the contactless transmission. In this context, the first protocol provides a transmission of control information and payload, the payload of the first protocol including the control information and the payload of the predetermined protocol. The apparatus further includes a module coupled to the interface and being operative to exchange, using the payload of the first protocol, the control information and the payload of the predetermined transmission protocol for the data exchanged contactlessly by the near field communicator.

Abstract: The arrangement has a chip card controller (2) with connections connected with International Organization for Standardization (ISO) interfaces (9, 15), where the connections have a connection (IOo). Another controller (3) has a controller connection that is coupled with a switch device (4) such that the connection of the card controller is connected with the controller connection. The connection is decoupled from the controller connection and is connected with one of the interfaces when the switch device is operated in one condition. An independent claim is also included for a method for operating a circuit arrangement.

Abstract: Before executing a partial operational run (TB), a subsystem (T) is displaced from an allowed state into a non-allowed state. This state does not impair execution of the partial operational run (TB), so long as the state of the subsystem is not evaluated. The partial operational run (TB) is executed. The subsystem state is reverted from the non-allowed state in accordance with the partial operational run (TB), back into the allowed state. The subsystem state is then evaluated. An independent claim is included for the corresponding data processing unit.

Abstract: The generator has a sequence providing unit (100) to provide 2n sequences of numbers, where n >= 2. A combination unit has an intermediate processing stage (102A) to combine the sequences to produce an intermediate processing sequence. A final processing stage (102B) combines the intermediate processing sequence with sub-groups (106A, 106B) of k sequences of numbers to obtain an output sequence, where k >= 1 and less than n. Independent claims are also included for the following: (a) a method for providing pseudo-random numbers (b) an encryption or decryption device having a pseudo-random number generator (c) an encryption or decryption method (d) a computer program containing a program code intended to implement a method for providing pseudo-random number or an encryption or decryption method.
