An electronic payment system developed at A*STAR will protect the privacy of customers recharging their electric vehicles.
Electric vehicles are becoming more popular due to their environmental credentials and relatively low running costs. However, most existing electric vehicles need to be recharged every 100 to 150 kilometers, with each recharge potentially exposing information related to a customer’s payment and location. Now, researchers at A*STAR have described a new system that would allow quick and easy money transfers at electric vehicle charging stations, without jeopardizing customer privacy.

“Cybersecurity is an important factor for payment systems, but it is often ignored by users or administrators until the system is being attacked,” says researcher Joseph Liu from the A*STAR Institute for Infocomm Research in Singapore. “No one should have their daily habits or behavior traced without their consent.”
The recharging of electric vehicles presents unique challenges for privacy, not least because some cars with solar panels are able to sell electricity back to the grid, meaning payments flow in both directions. Without tight security, payment companies or hackers could monitor where and when cars are charged, gaining insight into people’s lifestyles that could be exploited for targeted spam marketing.
“Some popular electronic payment systems like credit cards do not provide any privacy, while other systems like prepaid cash cards may not be suitable for large payments, or are not insured against card loss,” says Liu. “Cash is anonymous, but requires expensive machines to keep cash stores secure from thieves.”
The new system developed by Liu and co-workers is based on an in-car unit that resembles a smartphone or tablet and, along with a range of security benefits, allows two-way anonymous payments for recharging. Users can instantly shut down their accounts and retrieve unused credit. Also, if their car is stolen they can revoke the location privacy to help police trace the car. In the event of a dispute between a user and a supplier, either party can submit the claims to an independent judging authority for investigation.
The researchers tested their system by simulating three different types of attack: a hacker trying to track the transactions of an honest user, a user trying to underpay for services, and a supplier trying to slander an honest user. The system proved robust against all three attacks.
The team has now implemented a prototype of their secure charging system. They will install the tamper-proof in-car units on a fleet of 100 new electric vehicles that will arrive in Singapore later this year, thanks to collaboration with the Chinese carmaker BYD Auto.

The IPH presents a solution at HANNOVER MESSE 2015 to make ship traffic more reliable while decreasing the maintenance costs at the same time. In cooperation with project partners, the research institute from Hannover, Germany, has developed a sensor system which continuously monitors the condition of the marine gearbox, thus preventing breakdowns. Special feature: the monitoring system works wirelessly and energy-autonomously. The required electrical power is generated where it is needed – directly at the sensor.
As well as cars need to be certified regularly (in Germany by the TÜV – Technical Inspection Association), ships need to be inspected – if the powertrain stops...
When an earthquake hits, the faster first responders can get to an impacted area, the more likely infrastructure--and lives--can be saved.
The Atlantic overturning is one of Earth’s most important heat transport systems, pumping warm water northwards and cold water southwards. Also known as the Gulf Stream system, it is responsible for the mild climate in northwestern Europe.
Scientists now found evidence for a slowdown of the overturning – multiple lines of observation suggest that in recent decades, the current system has been...
Because they are regularly subjected to heavy vehicle traffic, emissions, moisture and salt, above- and underground parking garages, as well as bridges, frequently experience large areas of corrosion. Most inspection systems to date have only been capable of inspecting smaller surface areas.
From April 13 to April 17 at the Hannover Messe (hall 2, exhibit booth C16), engineers from the Fraunhofer Institute for Nondestructive Testing IZFP will be...
