Abstract
A method for data transmission between a sensor and an electronic control and/or regulating unit (ECU), the transmitted sensor data (x, . . . , x) and the sensor being secured against a manipulation. The system provides a particularly simple, but very secure method for manipulation protection, the sensor data (x, . . . , x) 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.
