Privacy-preserving authentication and billing for dynamic charging of electric vehicles

Dynamic charging of electric vehicles (EVs) is a promising technology for future electrified transportation. By installing wireless charging pads under the roadbed, dynamic charging allows EVs to charge their batteries while moving through magnetic induction between the wireless charging pad and the receiving coil attached to the EV's battery. A pre-requisite for dynamic charging in practice is the support of cyber infrastructure and protocols. Although many research efforts aim to increase the charging efficiency and remove the physical barriers of dynamic charging, protocols in the cyber space that support dynamic charging is still lacking, especially protocols for digital authentication and billing. Due to EV's high mobility, location privacy is also an important research issue. In this thesis we present three protocols: FADEC, Portunes, and Janus, that together provide privacy-preserving authentication and billing framework for dynamic charging of EVs. The protocols are tailored towards the dynamic charging scenario to reduce real-time computation and communication overhead, and uses modern cryptography building blocks to preserve the EV's location privacy. Simulation results and implementations indicate that the presented protocols are efficient and feasible for future dynamic charging applications.
