Abstract. Intelligent vehicle technologies have been developed rapidly in recent year. Smart vehicles can exchange the essential information, such as the road and weather conditions, to guarantee the road safety. However, vehicles communicate with each other or the Road Side Unit (RSU) via wireless channel, which poses many challenges to fulfill the security requirements. In the data routing process, attackers can analyze, modify or drop the data packets to reveal the vehicles’ privacy or disturb the normal communication. In this paper, we devise a Security Aware Fuzzy embedded ACO routing algorithm (SAFACO) in VANETs, which combines digital signatures with fuzzy logic embedded ACO based routing protocol. After introducing the main structure of SAFACO, we also provide a detailed discussion of its security mechanism. The proposed secure communica‐ tion scheme is able to provide the authentication, ensure the data consistency, preserve the privacy of vehicles, also to detect and isolate malicious vehicles.

Introduction
1.1 VANETs Vehicular Ad hoc Networks (VANETs) are special MANETs, which usually consist of fast moving vehicles and some well-equipped Road Side Units (RSUs). Due to the high mobility of vehicles, the topology of a VANET is changing frequently. Therefore, the transmission time of data packets in this kind of networks is strongly limited. However, vehicles normally move along the roads. Based on observed mobility patterns, their position could be reasonably predicted. There are three different types of communications in VANETs: The Vehicle-toVehicle communication (V2 V), the Vehicle-to-Infrastructure communication (V2I) and the communication between the roadside devices. In order to communicate with the RSUs, On-Board Units (OBUs) are installed in the vehicles. It is a core element of next generation intelligent transportation systems (ITS), which aiming to manage vehicle traffic and assist drivers with safety information etc. VANETs can be distinguished from other types of ad hoc networks by the following features [1, 2]: © Springer Nature Singapore Pte Ltd. 2017 K.

1. Dynamic and rapidly-changing network topology: Due to the high speed of vehicles and limited transmission range of vehicles and RSUs, the topology of the vehicular networks is highly dynamic changing. According to the 801.11p specification, 1000 m is the maximum wireless transmis‐ sion range of each vehicle [1]. Suppose that if there are two vehicles moving in opposite directions, the connectivity of the network may change rapidly 2. Predictability of vehicular pathway: Nowadays, most vehicles ar
