Classification: CPC G  H | IPC G  H

Claim 9:
10. A method of a computing device for control of a motor vehicle, the method comprising:
receiving, by at least one processor of the computing device and from at least one external unit, (a) first messages for processing for the motor vehicle control and (b) subsequent to the receipt of the first messages, second messages for processing for the motor vehicle control;
while the at least one processor performs the processing of the first messages after the cryptographic module has provided a result an authentication procedure executed for the first messages that had been provided to the cryptographic module, storing, by the computing device, individual respective ones of the received second messages at least temporarily into a memory, message by message, as the individual respective ones of the second messages are received by the at least one processor without providing any of the individual respective ones of the received second messages to the cryptographic module; and
after the storing of all of the received second messages and responsive to (a) expiration of a predefined time period during which the receipt of the second messages occurred or (b) a number of the received second messages reaching a predefined threshold number, providing, by the at least one processor, all of the stored second messages to the cryptographic module, which is configured to execute the authentication procedure respectively for each of the second messages individually, the respective authentication procedure including (a) a respective check of whether the respective individual one of the second messages provided to the cryptographic module is authentic or (b) a respective assignment of a respective cryptographic signature to the respective individual one of the second messages.
