  • Method and apparatus for transmitting a message sequence over a data bus and method and apparatus for detecting an attack on a message sequence thus transmitted
    Patent number: 11394726
    Abstract: The present invention relates to a method for transmitting a message sequence via a data bus. The method comprises the transmission of an informational message containing an informational signal during an active phase, the transmission of a security message for initiating a rest phase and the transmission of rest messages containing a rest signal at the interval of a rest cycle time during the rest phase, wherein the informational signal and the rest signal differ from each other and wherein the security message and the rest messages differ from each other. Furthermore, the invention relates to a device for transmitting a message sequence via a data bus as well as a method and a device for detecting an attack on a message sequence transmitted via a data bus.
