-39. (canceled)
An attack detection method for a bus system of a motor vehicle, wherein communication rules are defined for the transmission of messages, the attack detection method comprising:
- receiving messages sent via the bus system;
- and
- analyzing whether the received messages are received according to the communication rules,
- wherein the communication rules predefine a changeover of a message cycle depending on a predefined event and the analysis determines whether the received messages are received according to the predefined changeover of the message cycle.
An attack detection device for a bus system for a motor vehicle, comprising:
- a microprocessor, wherein the attack detection device is configured to receive messages via the bus system and the microprocessor is configured to carry out an attack detection method for the bus system of the motor vehicle, wherein communication rules are defined for the transmission of messages, the attack detection method comprising receiving messages sent via the bus system, and analyzing whether the received messages are received according to the communication rules, wherein the communication rules predefine a changeover of a message cycle depending on a predefined event and the analysis determines whether the received messages are received according to the predefined changeover of the message cycle.
A bus system for a motor vehicle, comprising:
- at least one bus line and a plurality of bus participants configured to exchange messages with one another via the bus line, wherein at least one bus participant is configured to carry out an attack detection method for the bus system of the motor vehicle, wherein communication rules are defined for the transmission of messages, the attack detection method comprising receiving messages sent via the bus system, and analyzing whether the received messages are received according to the communication rules, wherein the communication rules predefine a changeover of a message cycle depending on a predefined event and the analysis determines whether the received messages are received according to the predefined changeover of the message cycle.
