20120303973 | METHOD FOR PROTECTING SENSOR DATA FROM MANIPULATION AND SENSOR TO THAT END - In a method for protecting sensor data from manipulation, in the context of an authentication of the sensor, a number used once is sent from a control unit to the sensor, the sensor generating with the use of the number used once a cryptographic authentication message and sending at least a first part of the cryptographic authentication message to the control unit. In addition, the sensor data are provided with a cryptographic integrity protection, time-variant parameters being added to the sensor data and the sensor data being sent with the cryptographic integrity protection and the added time-variant parameters from the sensor to the control unit. For calculation of the initial parameters, at least a second part of the cryptographic authentication message is utilized. | 11-29-2012 |
20130003966 | Cryptographic hardware module and method for updating a cryptographic key - A cryptographic hardware module has an arithmetic unit, a memory storing at least one first key, a logic and a cryptographic device. The hardware module loads at least one second encrypted key into the hardware module and decrypts the at least one second encrypted key via the cryptographic device using the at least one first key. | 01-03-2013 |
20130128664 | MEMORY MODULE FOR SIMULTANEOUSLY PROVIDING AT LEAST ONE SECURE AND AT LEAST ONE INSECURE MEMORY AREA - A memory module has at least one secure and at least one insecure memory area, separate write/read electronic units for each of the memory areas and at least one shared analog circuit part such as a voltage supply circuit for supplying the write/read electronic units and/or the memory areas. | 05-23-2013 |
20140298458 | DEVICE AND METHOD FOR PROCESSING DATA - An electronic device for processing data includes: an input interface for receiving input data; a processing module for processing data; and an encoding unit configured to encode data words received at the input interface as input data, in order to obtain encoded data words. The encoding unit is configured to encode the data words in such a manner that a specified proportion of all encoded data words have a specified Hamming distance and/or a specified Hamming weight. The processing module is configured to process the encoded data words. | 10-02-2014 |
20140298459 | Device and method for processing data - A device for processing data, the device having an input interface for receiving input data and a processing module for processing data, characterized in that an encoding unit is provided, which is configured to encode data words received at the input interface as input data, in order to obtain encoded data words; measured values characterizing the encoded data words and/or their processing by the device being ascertainable for encoded data words as a function of at least one physical variable of the device; the encoding unit being configured to encode the data words in such a manner, that a specifiable proportion of all measured values, which may be at least approximately 50% of all measured values, exhibit a difference from the setpoint value, which is less than or equal to a specifiable threshold value; and the processing module is configured to process the encoded data words. | 10-02-2014 |
20140301550 | METHOD FOR RECOGNIZING A MANIPULATION OF A SENSOR AND/OR SENSOR DATA OF THE SENSOR - A method for data transmission between a sensor and an electronic control and/or regulating unit (ECU), the transmitted sensor data (x | 10-09-2014 |
20140344916 | METHOD FOR OPERATING A COMMUNICATION MODULE, AND COMMUNICATION MODULE - A method for operating a communication module of a network element of a communication network as well as the communication module itself are described. The communication module is embodied for the transmission of data. The network element has a communication module and an interface for communication with further network elements of the communication network. The communication module is embodied in such a way that the transmission, via the interface, of data for transmission is inhibited or authorized on the basis of a filter instruction. | 11-20-2014 |
