Abstract: A sensor module for detecting at least one physical variable. The sensor module is configured to relay measured values, which characterize the at least one physical variable, to an external unit. The sensor module is configured to form a message authentication code and relay it to the external unit. The message authentication code allows the authenticity and integrity of at least one measured value to be checked.

Abstract: A method for data transmission between a sensor and an electronic control and/or regulating unit (ECU), the transmitted sensor data (x1, . . . , xt) and the sensor being secured against a manipulation. The system provides a particularly simple, but very secure method for manipulation protection, the sensor data (x1, . . . , xt) being transmitted via a first logical data transmission channel at a first data transmission rate, and security data (MAC; CMAC) for securing the transmitted sensor data and/or the sensor being transmitted via a second logical data transmission channel at a second data transmission rate from the sensor to the ECU. At least once at the beginning of a data transmission session, a session key is transmitted from the ECU to the sensor via a third logical data transmission channel and received by the latter, the session key being used at least for the ongoing session to generate the security data.

Abstract: A method for transmitting a sequence of data blocks to be transmitted includes: one first piece of authentication data and one second piece of authentication data different from the first are formed relative to a selected data block; the selected data block, the first piece of authentication data and the second piece of authentication data are transmitted to a receiver; and the receiver checks (i) a validity of the received data block with the aid of the received first piece of authentication data and (ii) a validity of the received first piece of authentication data with the aid of the received second piece of authentication data.
