Problems solved by technology

For example, it may be difficult or impossible for a hacker to correctly deduce the output of a DMO that may be provided as part of a CAN bus message, since the parameters used in computing the DMO may not be well known

Embodiment Construction

[0014] The following description relates to systems and methods for determining the presence of hacking or malicious interference in a communication system in a vehicle. in figure 1 Shown in is a vehicle engine system, which may include sensors and actuators communicatively coupled to an ECU, which communicates / communicates with a CAN bus including a Threat Assessment Gateway (TAG). in figure 2 The CAN bus is described in, which includes related CAN nodes such as TAG and various ECUs. Communication on the CAN bus can be via such as Figure 3A The CAN frame described in the CAN frame may include a checksum and DMO according to the present disclosure, such as Figure 3B Those described in. according to Figure 4 The method shown in can use DMO to detect the existence of hacking, or to distinguish hacking and transmission errors. according to Figure 5 The method shown in can also use engine operating parameters and other considerations to help distinguish between errors caused ...

Abstract

The invention relates to systems and methods for security breach detection in vehicle communication systems. 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 / orunexpected 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.

Description

Technical field [0001] This application generally relates to methods and systems for communication security in vehicles, in particular detecting breaches, hacking, or malicious tampering in one or more systems in vehicles that are communicatively connected to a bus or other communication paths Methods and systems. Background technique [0002] Modern vehicle systems increasingly rely on electronic communication. Communication between different engine subsystems, sensors, actuators, electronic control units (ECU), and other systems can improve vehicle control, but such systems are vulnerable to hacking or malicious tampering. This problem is compounded by the fact that many vehicle systems can be communicatively coupled to each other via one or more buses, for example via a controller area network (CAN) bus. In the case where many ECUs or vehicle subsystems are in contact with each other via bus communication as is common in modern vehicles, even small digital security loopholes...
