Researchers develop cryptographic protocol which is immune to man-in-the-middle attacks, impersonation attacks, replay attacks and insider assaults while maintaining user anonymity and untraceability.

The National Institute of Technology Andhra Pradesh  researchers working with an international team have developed a protocol to address major security and privacy vulnerabilities in dynamic charging of electric vehicles. The institute worked with researchers from International Institute of Information Technology (IIIT) HyderabadIIIT Naya RaipurKyungpook National University (South Korea), and University of Wollongong (Australia), to develop the protocol.  

The research was led by Alavalapati Goutham Reddy from the Department of Computer Science and Engineering, NIT Andhra Pradesh. The research paper was co-authored by Raveendra Babu, research scholar, NIT Andhra Pradesh, and Ashok Kumar Das of IIIT Hyderabad, Ruhul Amin of IIIT Naya Raipur, Young-Ho Park of Kyungpook National University, South Korea, and Willy Susilo of University of Wollongong (UOW). 

A group of interdisciplinary researchers led by Alavalapati Goutham Reddy and Ashok Kumar Das developed an ‘Authentication with Key Agreement Protocol for EV Dynamic Charging Infrastructure Entities’ and published their findings in the 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. 

Alavalapati Goutham 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.” 

Static charging vs dynamic charging 

Researchers have studied static, quasi-static and dynamic charging systems. Static charging, which allows consumers to park at their homes or offices, needs the car to be immobile. It requires a connecting wire and a plug-in charger, causes range anxiety, and is unsafe in the wet. Quasi charging is used to charge vehicles that stop briefly, including at traffic lights or bus stops.  

However, once dynamic charging is deployed in the selected areas, quasi charging will be simple to execute. These challenges demand more investigation before global electric vehicle adoption. To address the aforementioned challenges, scientists have developed the most practical technique for charging electric vehicles on the go. ICPT is the most efficient method for charging electric vehicles while driving. 

Dynamic charging allows for on-the-go charging. This eliminates the need for large-capacity batteries and lowers battery costs. It 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. Dynamic charging will be a new revolution and a boon to the transportation sector.
