    摘要: A system for detecting and preventing, in real time, malicious broadcasting messages from an electronic control module attempting to attack a vehicle network is disclosed. The system includes electronic control modules in communication via a serial data link of the vehicle network. At least one electronic control module is configured to receive at least a portion of a serial message on the vehicle network transmitted by another electronic control module, identify the serial message as malicious based on the received portion of the serial message, and in response to identifying the serial message as malicious, inject a dominant bit into the serial message for the vehicle network to cause an error frame in the serial message. Other example systems and methods for detecting and preventing, in real time, malicious broadcasting messages are also disclosed.
