Challenges and future trends for embedded security in electric vehicular communications

Compared to fuel based vehicles, Electric Vehicles (EVs) have the advantages of fuel-saving, lower maintenance and reduced pollution etc. However, EVs bring new challenges for security as modern vehicles extensively interact with their environments, such as Wi-Fi, LTE and keyless entry system. These communication systems are cataloged into in-vehicle network and car to car/infrastructure (C2X) network. In this paper, we have addressed the importance of embedded security for electric vehicular communication, which provides confidentiality and privacy of the critical controlling information. In addition, we present the security solutions for electric charge station, which becomes another intrusion point because EVs must be charged frequently. Finally, we summarize the challenges and future trends of embedded security for electric vehicular communications.
