Abstract
A method for operating a data communication between functional units for a vehicle, in which a predefined number of data packets transmitted by a sending unit to a receiving unit is collected in a data buffer of the sending unit to generate a data block. In each predefined time step, one data packet is transmitted, in which the data packets are collected over a predefined collection period. A signature for authenticating the data block is then determined, the signature being determined over a predefined determination period lasting for multiple time steps. The signature is then sent in multiple parts from the sending unit to the receiving unit over a predefined transmission period, with one part of the signature being sent per time step. The sum of the collection period, the determination period and the transmission period is less than a predefined system fault tolerance time.
