This VANET require a mechanism to authenticate message, identify valid vehicles and remove malevolent vehicles. Any query asked by the vehicles from the server or system should be properly authenticated. In this we are using RC6 encryption and decryption algorithm for providing security of the message and Adhoc on demand distance vector (AODV) routing protocol to exchange the message. The advantage of this is that by using real tine road condition to compute the better route and at the same time, prevents from the traffic congestions Keywords: Navigation, privacy preservation, RC6 encryption, Vehicular Ad Hoc Networks, secure navigation protocol and AODV routing protocol. 1. INTRODUCTION In a certain destination route finding is a common experience for all among the drivers. Roads have always been dangerous, and a lot of efforts have been undertaken to improve their safety. In old days the hard copy of atlas is used by most of the drivers. But it was very time consuming. After that Global positioning system (GPS) has introduced [1]. Global positioning system (GPS) with navigation has introduced in [2]. Most of the driver has installed GPS on their vehicle for the better driving path. In this, based on local map data base route searching procedure is done but real time road conditions are not mentioned there. After that vehicular Adhoc network becomes very popular among all over the world. It is an important element of the Intelligent Transportation Systems (ITSs) [3]. In VANET, there are various elements. On Board Unit (OBU) is installed in the vehicles, Road Side Unit (RSU) is installed along the road and Trusted authority (TA) and some other informatics server are installed at the back end. The OBU and RSU communicate using the Dedicated Short Range Communications (DSRC) protocol [4]. The main function of VANET is to give a safety message that means turning direction, any accidental information etc. to drivers or any nearby vehicles. VANETs broadcasts the safety messages to vehicle to vehicle(V2V) and vehicle to infrastructure(V2I) or road side unit(V2R).In [5] A new VANET-based smart parking scheme for large parking lots has proposed. In this, to find a vacant parking space in a parking lot, various RSUs provide the navigation scheme to drivers. In [6], real-time traffic information from distributed sensor nodes (vehicle) is performed through the WiMAX interface. Various aspects and research work has given in [7],[8],[9],[10]. Recently, Chim et al [11] proposed a VANET-based secure and privacy-preserving navigation protocol (VSPN). In this, there is a anonymous credentials to provide secure navigation services to drivers. Samara et al. [12], have recently been summarized the Security issues and challenges of VANETs. AMOEBA at [13], was proposed to provide location privacy based on the concept of vehicle group navigation. Different security issues in VANETs has addressed in [14],[15]. Security and privacy-enhancing communications schemes were addressed in [16]. Pseudonym update to sustain privacy has addressed in [17]. For protecting drivers ‘privacy Identity-Based Encryption (IBE) was proposed in [18]. An efficient social-tier-assisted packet forwarding protocol STAP for achieving receiver-location privacy preservation in VANETs was proposed [19]. In this paper, we propose a navigation scheme for privacy preserving system in VANETs. In this, we concentrate on the communication between the vehicle and the infrastructure or two nodes must be more secure. At the same time we are also focus on the routing protocol that we are using is selects better route and prevents from the traffic congestion. The rest of the paper is organized as follow. In section 2, system model and security objectives are given. In section 3, the proposed protocol and algorithms are described for navigation scheme for privacy preserving system in VANETs, and conclude the paper in section 4. 2. SYSTEM MODEL 2.1 Architecture In this architecture, there are vehicles, RSUs that are installed along the road and trusted authority.
