Abstract
The present disclosure relates to suppressing malicious transmissions by overriding frames on a Controller Area Network (CAN) bus. In an embodiment, a method operates by determining when a frame arrives at a CAN bus. A determination of whether to override the frame is made based on an arbitration ID of the frame received from the CAN bus. In response to determining to override the frame, a predetermined sequence of bits is transmitted on the CAN bus during transmission of a data length code (DLC) field in the frame. A message to complete the frame is generated based on the predetermined sequence of bits. Then, the message is transmitted on the CAN bus.
