摘要: Message authentication, to ensure the receiving message is true and coming from claimed source, a key issue in vehicular ad hoc network (VANET) because may be life-critical, traffic information, or emergence transmitted by strange sources. Due nature of realtime high mobility VANET message, traditional PKI security schemes are not suitable for VANET. Aiding roadside unit (RSU) make authentication easily, but it still embedded some problems: how authenticate different RSU range, process vehicle’s hand-off among communication range. This paper proposes comprehensive scheme which enables intra inter within RSUs. The proposed makes balance overhead computation communication, against attacking. results efficiency analysis comparison with related works show superior method
