    摘要: 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.

    摘要: In a method for verifying a memory block of a nonvolatile memory, at a first point in time, a first authentication code for the memory block is determined while using a secret keyword and is stored in an authentication code memory table, and at a second point in time, for the verification, a second authentication code for the memory block is determined while using the secret keyword and is compared to the first authentication code and the memory block is verified if the first authentication code and the second authentication code agree.
