AUTOCRYPT - Electric Vehicles and Charging

The adoption and usage of Electric Vehicles (EVs) is very quickly on the rise.

In a Battery Electric Vehicle (BEV), the motor and the car itself is powered by a battery, which requires regular charging. While this concept may seem simple enough (drive, charge, back on the road), the EV ecosystem is about much more than just charging. EVs are also connected to a larger network, and therefore along with the charge points, are designed to send and receive data.

As such, the electric vehicle charging system involves much more than just the vehicle and the charger: a variety of service providers and payment management systems are working simultaneously in order to keep vehicles on the road.

Because of the number of involved parties in the EV ecosystem, it is absolutely essential to have a security system involved in the entire lifecycle to ensure secure data communication.AutoCrypt V2G provides PKI systems to keep communication secure between the vehicle and the charging point, meaning authentication, authorization, and the entire payment system stay secured.

Various changes in the automotive industry have allowed this to happen.

Although the recent COVID-19 pandemic has affected the traditional car market(e.g., declines over 30% across most European countries), in comparison the EV market has only grown.

Hypotheses point to the fact that work-from-home (WFH) situations have led driversto only travel short distances, making EVs the ideal mode of transport.With more and more new EV models appearing on the market, EVs are becoming an affordable and efficient way of transportation.

Also contributing to the increase in sales is the growing number of charging points throughout the world.

Needless to say, EVs will be a large part of the Smart Mobility movement. They contribute to the wellbeing of the environment – improving the quality of the air, lessening noise pollution and greenhouse emissions, and contribute to a much better energy consumption system with the possibilities of bidirectional charging.

However, new technology always requires a fundamental base of security becausethe innovative nature of the technology invites attacks from those with ill-intent.

Driving an Electric Vehicle (EV) is about much more than just charging the battery.

When charging the vehicle, information is exchanged. This information may include sensitive data like:

Credit card / payment information

Personal Identifiable Information (PII)

Car data

There are still charging stations that use older, open charging protocols that do not use encryption for data communication. Without proper protocols in place, systems can be more vulnerable to attacks.

For example, an attacker can take advantage of a vulnerability to gain root access to the charge point, take payment data, and wreak financial havoc on the part of the charge point operators, mobility operators, as well as the vehicle owner in question.

The attacker could gain access to the EV’s USB port, using merely a simple flash drive to copy logs and data, gaining access to personal information as well as sensitive car data.

AUTOCRYPT provides a Plug&Charge (PnC) environment that V2G participants can trust.

In compliance with ISO-15118 standards for the V2G communication interface,AutoCrypt V2G verifies identities of both the vehicle and the charger.AutoCrypt V2G also supports Open Charge Point Protocol (OCPP) ensuring that the contract between the charging station management systems (CSMS) and the mobility operators (MOs)is verified and safely delivered to the vehicle.
