20140337586 | MEMORY DEVICE - A memory device having a primary memory element, in which the memory device includes an evaluation device to ascertain whether the primary memory element experiences a state change and to activate a secondary memory element so that if (a) the primary memory element experiences a state change, the secondary memory element does not carry out a state change, and if (b) the primary memory element does not experience a state change, the secondary memory element carries out a state change. | 11-13-2014 |
20150016193 | CIRCUIT CONFIGURATION AND OPERATING METHOD FOR SAME - A circuit configuration is described including a first input for inputting a first set of digital input data, an output for outputting digital output data, and a control input for receiving a control signal. At least two register units are provided and the circuit configuration is designed to write, as a function of the control signal, into a first register unit optionally at least a part of the first set of input data or of the second set of digital input data and to write into a second register unit optionally at least a part of the first set of input data or of the second set of input data. | 01-15-2015 |
20150270973 | DEVICE AND METHOD FOR CARRYING OUT A CRYPTOGRAPHIC METHOD - A device for carrying out a cryptographic method includes: a cryptographic unit carrying out at least one step of the cryptographic method; and a functional unit carrying out a deterministic function as a function of input data supplied to the device and at least one secret key. | 09-24-2015 |
20150382185 | METHOD AND DEVICE FOR COUPLING TWO COMMUNICATION PARTNERS - For coupling a first communication partner with a second communication partner, a signal source sends a radio signal to the first communication partner via a first channel. The first communication partner ascertains a first measured value of a measuring variable related to the first channel during the receiving of the radio signal, ascertains a first comparative value as a function of the first measured value, and sends the first comparative value to the second communication partner. The second communication partner ascertains a first relationship measure between the first comparative value and a second comparative value, and couples with the first communication partner if the first relationship measure exceeds a specified threshold value. | 12-31-2015 |
20150382192 | Method and device for authenticating a mobile device - A method for authenticating a mobile device includes: probing by the mobile device a fading channel which connects the mobile device to a first radio base station; determining a secret held in common with the first radio base station as a function of a physical property of the fading channel; storing the in-common secret; receiving a first request for the in-common secret from a second radio base station; and, in response to the first request, sending a proof of knowledge of the in-common secret to the second radio base station. | 12-31-2015 |
