Patent Application
20170200323
Modern vehicles are typically controlled and monitored by multiple Electronic Control Units (ECUs) that coordinate their operations by communicating over one or more internal network buses. In addition, modern vehicles are becoming ever more connected through external network interfaces, such as those supporting Radio-frequency Identification (RFID), Bluetooth, Dedicated Short Range Communications (DSRC), Wi-Fi, and cellular communications protocols. This connectivity, on the one hand, facilitates a variety of services including telematics, navigation and safety that provide significant benefits for automakers, aftermarket vendors, fleet managers and passengers. But on the other hand, these capabilities introduce new security and privacy concerns. For example, researchers have highlighted the vulnerability of modern vehicles to cyber-attacks, such as by evading vehicle network defenses and infecting ECUs with malware to control a wide range of essential vehicle functions. Various intravehicular mechanisms for improving security have been proposed by the industry and academia. However, such intravehicular mechanisms are typically limited by inadequate computational and memory resources, access to data within the vehicle and in the vehicle's immediate vicinity only, and often sporadic, unreliable and expensive connectivity with external service providers.
In one aspect of the invention a method is provided for cooperative vehicle monitoring, the method including, at an intravehicular monitor configured with each of a plurality of vehicles, gathering any in-vehicle data associated with the vehicle, detecting any intravehicular anomaly associated with the vehicle by analyzing the in-vehicle data, and reporting intravehicular information including any of the detected intravehicular anomaly and the in-vehicle data, and, at an extravehicular monitor, detecting any anomaly by analyzing the reported intravehicular information in combination with extravehicular data that are external to the plurality of vehicles, and reporting any of the intravehicular information, the extravehicular data, and any anomaly detected at the extravehicular monitor
In other aspects of the invention systems and computer program products embodying the invention are provided.
Aspects of the invention will be understood and appreciated more fully from the following detailed description taken in conjunction with the appended drawings in which:
Embodiments of the invention may include a system, a method, and/or a computer program product. The computer program product may include a computer readable storage medium (or media) having computer readable program instructions thereon for causing a processor to carry out aspects of the invention.
The computer readable storage medium can be a tangible device that can retain and store instructions for use by an instruction execution device. The computer readable storage medium may be, for example, but is not limited to, an electronic storage device, a magnetic storage device, an optical storage device, an electromagnetic storage device, a semiconductor storage device, or any suitable combination of the foregoing. A non-exhaustive list of more specific examples of the computer readable storage medium includes the following: a portable computer diskette, a hard disk, a random access memory (RAM), a read-only memory (ROM), an erasable programmable read-only memory (EPROM or Flash memory), a static random access memory (SRAM), a portable compact disc read-only memory (CD-ROM), a digital versatile disk (DVD), a memory stick, a floppy disk, a mechanically encoded device such as punch-cards or raised structures in a groove having instructions recorded thereon, and any suitable combination of the foregoing. A computer readable storage medium, as used herein, is not to be construed as being transitory signals per se, such as radio waves or other freely propagating electromagnetic waves, electromagnetic waves propagating through a waveguide or other transmission media (e.g., light pulses passing through a fiber-optic cable), or electrical signals transmitted through a wire.
Computer readable program instructions described herein can be downloaded to respective computing/processing devices from a computer readable storage medium or to an external computer or external storage device via a network, for example, the Internet, a local area network, a wide area network and/or a wireless network. The network may comprise copper transmission cables, optical transmission fibers, wireless transmission, routers, firewalls, switches, gateway computers and/or edge servers. A network adapter card or network interface in each computing/processing device receives computer readable program instructions from the network and forwards the computer readable program instructions for storage in a computer readable storage medium within the respective computing/processing device.
Computer readable program instructions for carrying out operations of the invention may be assembler instructions, instruction-set-architecture (ISA) instructions, machine instructions, machine dependent instructions, microcode, firmware instructions, state-setting data, or either source code or object code written in any combination of one or more programming languages, including an object oriented programming language such as Java, Smalltalk, C++ or the like, and conventional procedural programming languages, such as the “C” programming language or similar programming languages. The computer readable program instructions may execute entirely on the user's computer, partly on the user's computer, as a stand-alone software package, partly on the user's computer and partly on a remote computer or entirely on the remote computer or server. In the latter scenario, the remote computer may be connected to the user's computer through any type of network, including a local area network (LAN) or a wide area network (WAN), or the connection may be made to an external computer (for example, through the Internet using an Internet Service Provider). In some embodiments, electronic circuitry including, for example, programmable logic circuitry, field-programmable gate arrays (FPGA), or programmable logic arrays (PLA) may execute the computer readable program instructions by utilizing state information of the computer readable program instructions to personalize the electronic circuitry, in order to perform aspects of the invention.
Aspects of the invention are described herein with reference to flowchart illustrations and/or block diagrams of methods, apparatus (systems), and computer program products according to embodiments of the invention. It will be understood that each block of the flowchart illustrations and/or block diagrams, and combinations of blocks in the flowchart illustrations and/or block diagrams, can be implemented by computer readable program instructions.
These computer readable program instructions may be provided to a processor of a general purpose computer, special purpose computer, or other programmable data processing apparatus to produce a machine, such that the instructions, which execute via the processor of the computer or other programmable data processing apparatus, create means for implementing the functions/acts specified in the flowchart and/or block diagram block or blocks. These computer readable program instructions may also be stored in a computer readable storage medium that can direct a computer, a programmable data processing apparatus, and/or other devices to function in a particular manner, such that the computer readable storage medium having instructions stored therein comprises an article of manufacture including instructions which implement aspects of the function/act specified in the flowchart and/or block diagram block or blocks.
The computer readable program instructions may also be loaded onto a computer, other programmable data processing apparatus, or other device to cause a series of operational steps to be performed on the computer, other programmable apparatus or other device to produce a computer implemented process, such that the instructions which execute on the computer, other programmable apparatus, or other device implement the functions/acts specified in the flowchart and/or block diagram block or blocks.
The flowchart and block diagrams in the Figures illustrate the architecture, functionality, and operation of possible implementations of systems, methods, and computer program products according to various embodiments of the invention. In this regard, each block in the flowchart or block diagrams may represent a module, segment, or portion of instructions, which comprises one or more executable instructions for implementing the specified logical function(s). In some alternative implementations, the functions noted in the block may occur out of the order noted in the figures. For example, two blocks shown in succession may, in fact, be executed substantially concurrently, or the blocks may sometimes be executed in the reverse order, depending upon the functionality involved. It will also be noted that each block of the block diagrams and/or flowchart illustration, and combinations of blocks in the block diagrams and/or flowchart illustration, can be implemented by special purpose hardware-based systems that perform the specified functions or acts or carry out combinations of special purpose hardware and computer instructions.
Reference is now made to
IVM 104 preferably includes a communications monitor (CM) 106 configured to gather in-vehicle data, such as by monitoring communications between components of vehicle 102A, such as between Electronic Control Units (ECUs) of vehicle 102A, communications directed to vehicle 102A from points of origin external to vehicle 102A, and communications from vehicle 102A to recipients external to vehicle 102A.
IVM 104 also preferably includes a local anomaly detector (LAD) 108 configured to detect anomalies associated with vehicle 102A by analyzing the gathered in-vehicle data. In one embodiment LAD 108 applies predefined rules 110 to communications monitored by CM 106 to identify communications that are not in compliance with their associated communication protocols (e.g., CAN, MOST, or LIN), and/or that deviate from expected behavior associated with such communications, such as from an expected message frequency of a given type of communications. In another embodiment LAD 108 acquires data from components of vehicle 102A and applies predefined rules 110, such as kinematic and thermodynamic rules, to identify when such data deviate from expected values, particularly in view of cross-correlations among the data, such as by identifying a gas pedal position that deviates from an expected position given the vehicle's current engine RPM, gear position, and velocity. Such anomalies may, for example, be caused by breakdown of vehicle components, by adverse road and weather conditions, by physical sabotage, or by cyber-attack, such as where malware is introduced to ECUs via external communications or by other means.
IVM 104 also preferably includes a report manager (RM) 112 configured to report information including any of the monitored communications, vehicle data, and detected anomalies described herein, as well as any metadata related thereto, in accordance with conventional reporting techniques. In one embodiment RM 112 reports detected anomalies to persons within vehicle 102A. In another embodiment RM 112 is configured to extract, and optionally compress and/or encrypt, a subset of any of the above information in accordance with predefined reporting protocols, and report the extracted information wirelessly to EVM 100. Redundant data, and data that are known to be in the recipient's possession or otherwise accessible to the recipient, are preferably omitted from reports by RM 112.
EVM 100 preferably includes a global anomaly detector (GAD) 114 configured to detect anomalies associated with any of the vehicles among vehicles 102. Such anomalies may include any of the anomalies described hereinabove with reference to LAD 108, as well as other types of anomalies, such as anomalies regarding elements that are external to vehicles 102, such as current or anticipated road and traffic conditions or automotive service providers affecting or potentially affecting any of vehicles 102. GAD 114 preferably identifies such anomalies by applying known machine learning techniques to the data received from vehicles 102 as described hereinabove, in combination with data that are external to vehicles 102, such as road map information, real-time traffic and weather information, past, current, and planned road repair information, driving rules, traffic and driving models, automotive service provider ratings and history, and automotive component failure statistics. For example Sinai, et al. (M. B. Sinai, N. Partush, S. Yadid, and E. Yahav, “Exploiting Social Navigation,” ArXiv Prepr. ArXiv14100151, 2014) describe a method for attacking the WAZE driver assistance application by spoofing traffic jams to influence traffic routing decisions. GAD 114 defends against such an attack by identifying as anomalies injections of false road and traffic data which do not accord with actual real-time traffic and road data.
EVM 100 also preferably includes an event analyzer 116 configured to identify the source or cause of any of the anomalies described hereinabove by applying predefined investigative techniques and rules. In one embodiment, event analyzer 116 identifies anomaly patterns and analyzes the patterns in order to identify commonalities. For example, event analyzer 116 may be configured to identify a particular service shop as the source of an anomaly where multiple vehicles from among vehicles 102 that were recently serviced by the same service shop all began shortly thereafter to exhibit an anomaly with respect to the same third party ECU. Event analyzer 116 is optionally configured to employ predefined forensic techniques to investigate suspected malicious security incidents by retracing the actions of vehicles 102, as well as of elements external to vehicles 102 where such information is available to event analyzer 116, such as by employing IBM Security QRadar Incident Forensics™, commercially available from IBM Corporation, Armonk, N.Y. Event analyzer 116 is optionally configured to employ predefined security vulnerability discovery techniques to proactively discover vehicle security vulnerabilities, such as a vulnerable ECU or network interface, based on any of the anomalies, data, and other findings described hereinabove, as well as suggest and prioritize remediation and mitigation activities related thereto, such as by employing IBM Security QRadar Vulnerability Manager™, commercially available from IBM Corporation, Armonk, N.Y.
EVM 100 also preferably includes a report manager (RM) 118 configured to report information including any of the any of the anomalies, data, and analysis described hereinabove, such as to a security operations center (SoC) analyst or to any of vehicles 102, in accordance with conventional reporting techniques.
