Abstract

A method is provided for protecting a vehicle network of a vehicle against manipulated data transmission, in which the vehicle network includes multiple network nodes, and at least one first network node in the vehicle network in a normal mode checking a first received message as to whether the first received message is a message assigned to the first network node in the normal mode, but which the first network node did not transmit. The first network node in a diagnostic mode further checks a second received message as to whether the second received message is a message assigned to the first network node in the normal mode or in the diagnostic mode, but which the first network node did not transmit.
