new delhihyderabad researchers from the national institute of technology andhra pradesh have developed a protocol to address major security and privacy vulnerabilities in dynamic charging of electric vehiclespopularising electric vehicles evs are part of indias focus on renewable energy policy in its action plan to combat climate changethe institute worked with researchers from iiit hyderabad iiit naya raipur kyungpook national university south korea and university of wollongong australia to develop this protocol a release said herethe international energy agency iea predicts that by 2030 the worldwide fleet of electric vehicles will reach 145 million as more people choose electric vehicles the demand for charging infrastructure would also growthis research was led by alavalapati goutham reddy assistant professor department of computer science and engineering nit the research paper was coauthored by raveendra babu research scholar nit andhra pradesh along with professor ashok kumar das of iiit hyderabad ruhul amin of iiit naya raipur professor youngho park of kyungpook national university and professor willy susilo of university of wollongongthis group of interdisciplinary researchers developed an authentication with key agreement protocol for ev dynamic charging infrastructure entities they published their findings in the reputed peerreviewed journal ieee transaction on vehicular technologythese 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 release claimedon 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 concernsas evs are electricpowered researchers have studied static quasistatic 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 plugin charger causes range anxiety and is unsafe in the wet quasicharging is used to charge vehicles that stop briefly including at traffic lights or bus stopsbabu 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 vehiclesdynamic charging allows for onthego charging and would be a new revolution and a boon to the transportation sector however it is still a work in progress because it requires precise coordination between electric vehicles highway infrastructure and charging stationsas a result of the wide range of communication principals involved novel technologies employed messages sent among communicating principals and charging infrastructure implemented in places like homes offices and public stations hint at several security issues to be considered such as message tampering spoofing or delaying among others to disconcert the charging servicethe designed protocol is immune to maninthemiddle attacks impersonation attacks replay attacks and insider assaults while maintaining user anonymity and untrace ability also the proposed protocol is more efficient than its counterparts in terms of
