Researchers Submit Patent Application, "Vehicular Intra Network Apparatus and Client-Host Method of Operation", for Approval (USPTO 20160378707)

Politics & Government Week |

By a News Reporter-Staff News Editor at Politics & Government Week -- From Washington, D.C., VerticalNews journalists report that a patent application by the inventors SIKAND, Shivinder Singh (Santa Cruz, CA); Drako, Dean (Austin, TX), filed on , was made available online on .

No assignee for this patent application has been made.

News editors obtained the following quote from the background information supplied by the inventors: "Technical Field

"Vehicle control and network security.

"Description of the Related Art

"In a conventional Controller Area Network (CAN) each node on the bus must listen to every transmission to establish priority and thus is vulnerable to attack and denial of service. What is needed is a more robust and secure network apparatus to couple legacy and next generation vehicle subsystems.

"This includes Security for doorlocks, Addressing inherent hackability of CANbus, enabling quicker time to market, less proprietary data, more open Domain Controllers, Higher bandwidth for sensors e.g. RADAR, safely mixing propulsion and non-propulsion packet traffic, all resulting in Provable Functional Safety/Automotive Safety Integrity Level."

As a supplement to the background information on this patent application, VerticalNews correspondents also obtained the inventors' summary information for this patent application: "A networking apparatus couples a plurality of vehicle nodes to improve bandwidth, security, and subsystem independence.

"The networking apparatus couples a plurality of thin client units to a single virtualized master control unit container host.

"Each thin client unit transforms CAN protocol messages to encrypted packets for a real time Ethernet interconnect.

"Vehicle subsystem modules connect via a personalized thin client unit which filters, corrects, and authenticates messages at the periphery of the networking apparatus.

"Between thin client units, the host encrypts and decrypts a message, directs the message to the proper recipient, authenticates each message, and centrally provides the functionality of a plurality of electronic control units.

"The virtualized master control unit container host may be updated over the air and perform installation and validation checks of a new version of one or more electronic control unit images while the vehicle is in operation using a previous version.

"Intrusion messages from malicious thin client units may be detected and suppressed.

"A vehicle subsystem can be independently improved without interfering with the operation of other subsystems.

"Noisy or defective data emitted by a sensor is filtered, corrected, or discarded by a thin client unit personalized to the appropriate functionality of the node.

"A real time Ethernet backbone couples a plurality of local client hubs to a single vehicle control unit. Each client hub only has an encryption/decryption engine, and a PHY modem coupled to a layer 2 Ethernet interface. The vehicle control unit creates a trust zone for each app and manages traffic across the backbone. Non-trivial computing is performed by a central containerized platform. This includes diagnostics for failures as well as malicious intrusion detection.

"A single vehicle control unit transforms operator control indicia into a plurality of individual commands, and securely transmits said commands to actuators and control devices.

"An operating system provides an encrypted application programming interface to operate functions such as torque vectoring, cooling, braking, and battery management.

"The OS provides an isolating trust zone to each layer or application for authentication and validation.

"Upgrades are available to install new features or improvements after a vehicle is in the field.

"Independent developers may test and furnish new capabilities without exposing or corrupting the IP of other vehicle modalities.


"To further clarify the above and other advantages and features of the present invention, a more particular description of the invention will be rendered by reference to specific embodiments thereof which are illustrated in the appended drawings. It is appreciated that these drawings depict only typical embodiments of the invention and are therefore not to be considered limiting of its scope. The invention will be described and explained with additional specificity and detail through the use of the accompanying drawings in which:

"FIG. 1 and FIG. 2 are system block diagrams of network apparatuses of the subject matter;

"FIG. 3-4 is a data flow diagram of components in a secure network; and

"FIG. 5-6 is a block diagram of software components shown as a rotated stack."
