Researchers to create cryptographic protocols that address security and privacy

The protocol is resistant to man-in-the-middle attacks, camouflage attacks, replay attacks, and internal attacks and does not detect and detect user identities and has higher computing and communication costs.

Researchers at the National Institute of Technology Andhra Pradesh, working with an international team, have developed a protocol to address key security and privacy vulnerabilities in the dynamic charging of electric vehicles.

The Institute has worked with researchers from IIIT Hyderabad, IIIT New Raipur, Kyungpook National University (South Korea) and University of Olongapo (Australia) to develop this protocol.

A team of interdisciplinary researchers led by Dr. Alavalapati Gotham Reddy and Prof. Ashok Kumar Das have developed an authentication with the key agreement protocol for the EV Dynamic Charging Infrastructure entity and published their findings in the renowned vehicle technology peer-review journal IEEE. These results show that messages exchanged between electric vehicles and dynamic charging infrastructure are secure, preventing attackers from tracking vehicles and gaining any advantage.

Since electric vehicles are electrically powered, researchers have studied static, quasi-static and dynamic charging systems. Static charging, which allows consumers to park their home or office, requires the car to be stationary. This requires a connecting cable and a plug-in charger range of concern and unsafe in wet conditions. Quasi charging is used to charge briefly stopped vehicles, including traffic lights or bus stops.

However, once dynamic charging is deployed in the selected area, quasi-charging will be easier to implement. These challenges demand further investigation before the adoption of electric cars worldwide. To address these challenges, scientists have developed the most practical strategies for charging electric vehicles on the go. ICPT is the most effective method for charging electric vehicles while driving.

Dynamic charging allows on-the-go charging. This eliminates the need for large-capacity batteries and reduces battery consumption. Dynamic charging allows electric vehicles to be charged while driving by burying charging pads (CPs) at the bottom of the road. This saves time for drivers who no longer have to stop at charging facilities. Dynamic charging will be a new revolution and a boon for the transport sector.

Dynamic charging is still a work in progress because it requires precise coordination between electric vehicles, highway infrastructure and charging stations. As a result of the extensive communications principal’s involvement, innovative technology has been employed, messages have been sent to communications heads, and the charging infrastructure implemented in places such as homes, offices and public stations, suggests a number of security considerations, such as message tampering. , Spoofing, or disturbing delayed charging service among others.

The designed protocol is based on elliptical curve cryptography, hash functions and chains, combinations and exclusive or operations, which facilitates its implementation. The protocol protects against man-in-the-middle attacks, camouflage attacks, replay attacks, and internal attacks when the user’s identity is kept secret and cannot be found. Also, the proposed protocol is more efficient than its counterpart in terms of computing and communication costs.
