“…In the recent years, various authors have proposed privacy preserving authentication schemes for secure message communication. The two most common privacy preserving authentication schemes are the pseudonyms based privacy preserving scheme [4][5][6][7][8][9][10][11][12]22, 24], the group signature based privacy preserving scheme [13][14][15][16][17]. Each scheme provides solution to the secure privacy preserving message communication problems in VANET but all of them have some drawbacks.…”

Vehicular ad hoc networks (VANETs) provide spontaneous traffic related and emergency rescue messages to its users of the route thereby enable them with the trouble-free driving. VANETs send emergency messages in times of exigencies that save people"s lives from disasters. Doing such times it has been a great challenge to ascertain the authentication and privacy of the messages that are broadcasted. Generally when the messages are broadcasted without accommodating privacy the confidential information"s like the vehicle"s id and location are exposed which adversely affect the users. In this paper to ensure privacy to the users we have recommended TA to provide a verification signature to all the vehicles which is mandatory for a vehicle for all its communication purpose. Normally in the existing schemes, the messages are provided with single level or bi level privacy features but, in the proposed scheme the emergency messages are provided with the multilevel privacy features. In the proposed scheme the TA provides a long term Verification signature which is mandatory to all the vehicles that are registered under VANET and this signature is also necessary in receiving the secondary token and common token from RSU at each interval of time. The authentication of the message is verified with the help of common token and encrypted common token as a RSU Verification signature. Since the emergency messages require secure, timely and factual communication our proposed protocol EMPPA scheme recommend the distribution of multiple verification signatures and tokens at various interval of time, so that the privacy, security and the authentication of messages are ensured to the VANET users.

“…PACP does not rely on storing multiple pseudonym certificates issued from a centralized authority or on providing identity certificates to the RSU for generating on-the-fly pseudonym certificates. Instead, a node generates its pseudonyms with assistance from the RSU in its neighborhood in a way that the RSU gains no information about the node's real identity may increase computational cost [5]. Genetic algorithm is used to find the optimal path from source and destination node [12].…”

A Vehicular Ad-hoc Network (VANET) consists of the vehicle to vehicle and vehicle to roadside communication. Growing the density of the vehicles on the road causes flooding while transferring packets from a source to one or multiple destinations over a VANET. However, increasing vehicles on road may causes a problem such as redundancy, congestion, collision and increasing delay though receiving emergency warnings. As long as reliable and proficient multi-hop broadcast in vehicular ad hoc networks is challenging one. In the proposed system commence a new protocol which uses the character of elegant route establishment and selection method for transfer information to the destination (dst) with minimum redundancy, delay and highest bits per second delivery. In some environment vehicles are deployed in a dense manner, and it can move at a high speed. Adjacent Access Points (APs) on the road find out route information from their past report gatherings which use a fuzzy logic to select routing conclusion. This approach consists of isolating the whole network area into clusters. Based on which an optimized route is chosen using the input parameters as vehicle density, distance from the adjacent AP, vehicle mobility, receiving signal strength and delay should be jointly measured in the relay node selection. Though, these computation conflicts with each other depend on vehicle mobility. Hence, we employ fuzzy logic to handle this imprecise information to select forwarding vehicles by mutually taking into account of vehicle distance (d), mobility (v) and Receiving Signal Strength (RSS). The selected vehicle can provide an assure data forwarding with a high competence. The performance of the proposed scheme is evaluated on the metrics such as end-to-end delay, packet delivery ratio by varying vehicle speed, and density of vehicles.

In a recent paper, Shim (2012) presented a very interesting authentication scheme for vehicular sensor networks. Shim claimed that the scheme is secure against the highest adopted level of attack, namely the chosen-message attack (CID-CMA). Nevertheless, we find that the proof in Shim's paper does not actually prove that the scheme is secure in this level. Instead, it can only ensure that the scheme is secure in a strictly weaker level of attack, the adaptive chosen-identity and no-message attack (CID-NMA). In this paper, first we show that there exist some security risks in vehicular networks if a scheme, which is only secure against CID-NMA but not CID-CMA, is deployed. Hence, having the proof that the scheme is only CID-NMA is insufficient for the aforementioned application. That is, Shim did not prove that the proposed scheme can resist these kinds of attack. Here, we use a different approach to prove the scheme for security against CID-CMA. We note that this proof is essential to ensure that the scheme can indeed be used for the aforementioned scenario. In addition, we also show that the batch verification of the scheme, proposed in the same paper, may have non-negligible error. Two invalid signatures may give a positive result. We further improve the batch verification part so that the error rate can be reduced to negligible level.
