NIT Andhra Pradesh, international team develop protocol to address security in charging electric vehicles

NEW DELHI: The National Institute of Technology (NIT) Andhra Pradesh researchers have collaborated with an international team to develop a protocol to address major security and privacy vulnerabilities in dynamic charging of electric vehicles.

NIT worked with researchers from IIIT Hyderabad, IIIT Naya Raipur, Kyungpook National University (South Korea), and University of Wollongong (Australia), to develop this protocol. The research was led by Alavalapati Goutham Reddy, Assistant Professor, Department of Computer Science and Engineering, NIT Andhra Pradesh, a statement from NIT Andhra Pradesh said.

A group of interdisciplinary researchers led by Alavalapati Goutham Reddy and Professor Ashok Kumar Das developed an authentication with key agreement protocol for EV Dynamic Charging Infrastructure Entities and published their findings in the reputed peer-reviewed journal IEEE Transaction on Vehicular Technology.

These findings demonstrate that messages exchanged between electric vehicles and dynamic charging infrastructure are secure, preventing attackers from tracking the vehicle and gaining any benefits, the NIT statement read.

Explaining the key aspects of this research, Reddy, said: “A lot of effort needs to be done to make charging while driving a reality. This is because there are so many communication principles and so many different types of messaging and charging infrastructure established in public places that are prone to security and privacy concerns.”

Raveendra Babu, research scholar, Department of Computer Science, NIT Andhra Pradesh, said: “Authentication is the most critical step in safeguarding any data from attackers, we chose to develop secure and effective authentication protocols for multiple dynamic charging network models used by electric vehicles.”

Dynamic charging allows for on-the-go charging. This eliminates the need for large-capacity batteries and lowers battery costs. Dynamic charging allows Electric Vehicles to charge while driving by burying Charging Pads (CPs) beneath the road. This saves time for drivers who no longer need to stop at charging facilities, the statement added.
