A real-time parking service with proxy re-encryption in vehicular cloud computing

Find parking space is a big problem in almost every metro city in the world. It always leads to driver frustration, traffic congestion and air pollution. As a result, drivers highly desire real-time parking service. In this paper, we proposed a new real-time parking service in vehicular cloud computing. When drivers send parking service request to vehicular cloud, vehicular cloud will compute the suitable parking lot for drivers. Our proposed scheme not only provides real-time parking lot information for drivers, but also integrates proxy re-encryption into the scheme in protecting service provider's benefit. We also show that our scheme achieves many security requirements such as mutual authentication, user anonymity, data confidentiality, traceability and revocability.
