摘要： For verifying authorization associated with a first electronic device by a second electronic device, using symmetric key encryption, the second electronic device receives from the first electronic device encrypted data and metadata with a key space identifier and positional information. The key space identifier defines a cryptographic key hierarchy and the positional information defines in the cryptographic key hierarchy the cryptographic key used to generate the encrypted data. The second electronic device derives the cryptographic key by way of a one-way function from cryptographic keys stored in the second electronic device, using the key space identifier and the positional information received from the first electronic device. The second electronic device decrypts the encrypted data, using the derived cryptographic key, for verifying the authorization associated with the first electronic device.

摘要： An electronic circuit comprising a circuit module, a capacitor connected to the circuit module and a shutdown line providing a shutdown signal to the circuit module for suspending the circuit module. The electronic circuit further comprises a switching module for switching the capacitor such as to reduce discharging of the capacitor, depending on the shutdown signal. Particularly, the switching module disconnects the capacitor from ground. Disconnection takes effect when the circuit module is suspended or in power down mode because of the shutdown signal being provided.

摘要： The invention relates to a method for wrriting data into identification media of various types (IM-X, IM-Y) via assigned write/read stations WR. According to said method, a virtual, identification media-independent reference file system RFS is defined. All access keys RKi are replaced by a file system key FSK and all access rights ACi of subsections Bi are suspended and a file system FS, corresponding to the reference file system RFS, is initialized or written into the identification media: (FS(IM-X), FS(IM-Y)). In doing so, a file system starting point (FS-S(IM-X), FS-S(IM-Y)) is defined in the identification media (IM(FS) and in the assigned read/write stations WR(RFS) so that applications (App(RFS) corresponding to the virtual reference file system RFS can be written into the identification media and executed. The inventive method allows for the writing into or execution of generally defined applications (App(RFS) into initialized identification media of various types (IM-X(FS), IM-Y(FS)) without adapting them.

摘要： A method of communicating between a terminal device and a back-end system assigned to the terminal device, the terminal device receives via a direct wireless communication link an authorization code from the mobile communication device. Responsive to receiving the authorization code, the terminal device transmits via the direct wireless communication link to the mobile communication device a terminal report message which includes a message content part and a message addressing part. The mobile communication device transmits the terminal report message in a forwarding message via a telecommunications network to a remote message processing system determined by the addressing part. The remote message processing system determines from the addressing part the back-end system assigned to the electronic terminal device and transfers the content part of the terminal report message to the back-end system.

摘要： For detecting within a communication range of an antenna a contactless data storage device which is configured for inductive coupling with an electromagnetic field emitted by the antenna, a return signal is detected (S1) at the antenna during emission of an electromagnetic field pulse. During amplitude build-up of carrier oscillation at the beginning of the electromagnetic field pulse, an evaluation signal is generated (S2) based on the return signal, and the data storage device is detected (S3) based on the evaluation signal. By detecting the presence of the data storage device based on an evaluation signal generated during amplitude build-up, the detection of the data storage device can be initiated before carrier oscillation of the electromagnetic field pulse is stable. Consequently, the width of the electromagnetic field pulse can be shortened and, therefore, energy consumption for detecting the presence of the data storage device can be reduced.

摘要： An authorization system (10) includes a reader (1) for a reader-card interaction (92) with a card (2), and a logic module configured to assign the reader (1) and the card (2) to each other and to make operable the reader-card interaction (92) based on authorization data comprising reader data and card data. The logic module is further configured to read via a non-contact interface (12.1) device data from an authorization storage device (5) and to assign the reader (1) to the card (2) based on the device data for making operable the reader-card interaction (92). The authorization storage device (5) is arranged spaced apart from the non-contact interface (12.1) at an essentially fixed distance (9), for example during the reader-device interaction (95). Using the device data makes it possible to enable efficiently the reader-card interaction (92) in case the reader data does not match the card data, for example.
