Recently an online electric vehicle (OLEV) concept has been introduced, wherevehicles are propelled through the wirelessly transmitted electrical power fromthe infrastructure installed under the road while moving. The absence ofsecure-and-fair billing is one main hurdle to widely adopt this promisingtechnology. This paper introduces a secure and privacy-aware fair billingframework for OLEV on the move through the charging plates installed under theroad. We first propose two extreme lightweight mutual authenticationmechanisms, a direct authentication and a hash chain-based authenticationbetween vehicles and the charging plates that can be used for differentvehicular speeds on the road. Second we propose a secure and privacy-awarewireless power transfer on move for the vehicles with bidirectionalauditability guarantee by leveraging game-theoretic approach. Each chargingplate transfers a fixed amount of energy to the vehicle and bills the vehiclein a privacy-aware way accordingly. Our protocol guarantees secure,privacy-aware, and fair billing mechanism for the OLEVs while receivingelectric power from the road. Moreover our proposed framework can play a vitalrole in eliminating the security and privacy challenges in the deployment ofpower transfer technology to the OLEVs.
