Abstract
Systems and methods for detection of security breaches in intravehicular communication systems are disclosed. In some embodiments, this may include intravehicular communication using messages sent with a checksum and a dynamic mathematical operator field. Errors in the checksum may be interpreted as ordinary transmission errors, whereas errors in the dynamic mathematical operator field may be interpreted as potential threats. Repeated errors in the dynamic mathematical operator, and/or unexpected messages in the intravehicular communications, may be interpreted as confirmed hacking. Upon confirmation of hacking, a warning may be issued to an operator and a vehicle safe mode may be entered, including restricting vehicle functionality.
