Abstract
A method for protecting a signal for transmitting a sequence of measurement values to a signal processing unit. The method includes a step of reading in at least one sequence of measurement values from a sensor and a step of processing the measurement values using a cyclical processing specification in order to determine a varied measurement value for each of at least two measurement values. Finally, the method comprises a step of sending the varied measurement values to the signal processing unit as measurement values from the sensor.
Claims10
A method for protecting a signal for transmitting a sequence of measurement values to a signal processing unit, the method comprising the following steps:
- reading in at least one sequence of measurement values from a sensor;
- processing the measurement values using a cyclical processing specification to determine a varied measurement value for each measurement value of at least two of the measurement values;
- and
- sending the varied measurement values to the signal processing unit as measurement values from the sensor;
- wherein in the processing step, the processing specification is configured to alternately link measurement values to a first predefined link value and a second predefined link value that differs from the first predefined link value to determine the varied measurement values.
A device configured to protect a signal for transmitting a sequence of measurement values to a signal processing unit, the device configured to:
- read in at least one sequence of measurement values from a sensor;
- process the measurement values using a cyclical processing specification to determine a varied measurement value for each measurement value of at least two of the measurement values;
- and
- send the varied measurement values to the signal processing unit as measurement values from the sensor;
- wherein in the processing, the processing specification is configured to alternately link measurement values to a first predefined link value and a second predefined link value that differs from the first predefined link value to determine the varied measurement values.
A non-transitory machine-readable storage medium on which is stored a computer program for protecting a signal for transmitting a sequence of measurement values to a signal processing unit, the computer program, when executed by a computer, causing the computer to perform the following steps:
- reading in at least one sequence of measurement values from a sensor;
- processing the measurement values using a cyclical processing specification to determine a varied measurement value for each measurement value of at least two of the measurement values;
- and
- sending the varied measurement values to the signal processing unit as measurement values from the sensor;
- wherein in the processing step, the processing specification is configured to alternately link measurement values to a first predefined link value and a second predefined link value that differs from the first predefined link value to determine the varied measurement values.
