报告摘要：
Electric vehicles are considered to be more environmental-friendly and their development are highly encouraged in many countries. One issue with electric vehicle is the slow re-charging of the battery (compared with re-fueling for traditional automobiles) and the need to re-charge frequently. We consider the charging pattern of electric vehicles and identify that a mechanism for charging station reservation for electric vehicle owners is desirable. We propose a privacy-preserving reservation system which provides a balance between privacy and user accountability. For instance, our system allows the vehicle owner to reserve a number of charging stations along the intended route at different time-slots yet at the same time no party, not even the system controller, can tell if all these reservations belong to the same owner. On the other hand, our system is secure against misuse in that a user can hold a limited number of reservation simultaneously. We demonstrate the practicality of our system with a prototype implementation on a smart phone. Finally, we also provide a security proof to show that our system is secure under well-known computational assumptions.
