Abstract
A method for securing a serial bus shared by a control module and one or more subordinate electronic devices, the serial bus having a protocol specifying that messages on the serial bus have a source address and a destination address. The method comprises examining, by one or more processors of the control module, each message appearing on the serial bus that was not originated by the control module; identifying, by one or more processors of the control module, a suspect message that satisfies one or more suspect message criteria. The method includes updating, by one or more processors of the control module, an event metric, and testing to determine whether a threshold has been exceeded; and in the event the threshold has not been exceeded, initiating, by one or more processors of the control module, a co-transmission sufficient to disrupt consumption of the suspect message by a subordinate device.
