AUTOMATICALLY SECURING CONNECTION TO A NETWORK ACCESS MEDIUM AT VEHICLE STATIONS

ABSTRACT

Presented herein are techniques for automatically obtaining a secure access Wi-Fi®

connection at a vehicle station. A cable and plug design is provided that enables a secure

Wi-Fi connection between vehicle and infrastructure for bulk data transfers. The

connection may be established by connecting a charging/gas cable for a vehicle.

DETAILED DESCRIPTION

Most vehicles today and of the future have several computers (e.g., engine control

units (ECUs)) on board that collect and process huge amounts of data. These modern

components may help enable electric charging and autonomous features of cars to establish

relevant new frameworks and products for the industry. These modern components

produce a large amount of data (e.g., on the order of terabytes) to be collected per day.

There is tremendous value in collecting this data. In the area of growing

opportunities in analytics, vehicle manufacturers and original equipment manufacturers

(OEMs) desire a mechanism to collect data on their vehicles as well as, for example, to

repair and update databases. However, due to the volume of data involved in the transfer,

traditional cellular networks have prohibitive costs. For security and safety reasons,

currently available techniques for collecting this data over open publicly accessible Wi-Fi

networks are also not prudent.

A vehicle extension (V2x) is provided to secure a vehicle to a station (e.g.,

supercharger stations for electric vehicles, standard gas stations, etc.) for Wi-Fi access. The

following description addresses specifically how to secure Wi-Fi network access, thereby

eliminating any requirement on the user to exercise additional steps involving

authenticating and enabling the Wi-Fi connection (e.g., by entering required credentials).

The solution involves an approach that can be readily implemented for electric

vehicles which are plugged to a wall charger or a charging station. An example uses a cable

and plug design that is equipped with near-field communication (NFC) capabilities for

credential exchange and authentication for Wi-Fi setup.

Figure 1 below illustrates an example overview of a system for EVs.

In Figure 2, the cable connected to the electric vehicle includes a low bandwidth

connection to a NFC module in the charger head. The vehicle is also equipped with another

NFC module mounted in or near the charger plug. The cable may also be equipped with an

actuator (e.g., a micro-switch or another sensor) that can detect when the cable is plugged

in or removed. This may trigger the NFC modules to exchange credentials necessary for

establishing a secure Wi-Fi connection. The exchange may include a certifica...
