Patent number: 11386201Abstract: A bus control device is enabled for placement between an input port to which a suspect device would be connected and the bus. In this manner, all message received from the suspect device, such an infotainment system, must pass through the bus control device. A separate intrusion detection device is coupled to the bus. The bus control device is arranged to output a notification message to the intrusion detection device, the notification message comprising information about the received message. The intrusion detection device is arranged to determine the validity of the received message responsive to the received notification message.Type: GrantFiled: August 6, 2017Date of Patent: July 12, 2022Assignee: C2A-SEC, Ltd.Inventor: Shlomo Oberman
