Abstract
A message filtering system for a communications system in a vehicle enabling communication between various systems and subsystems via a vehicle bus. Electronic devices may be coupled to the bus. Electronic control units (ECUs) may be located therebetween. The ECU may regulate or control the flow of messages between the bus and the electronic devices. Message filters may apply a filter policy to incoming and outgoing messages. In addition, the message filtering system may have an alert policy for violations of the filter policy. In one embodiment, the source identity of outgoing messages may be overwritten by a message filter dedicated to outgoing messages; this message filter may be an application specific integrated circuit.
