It should provide timely and accurate information for drivers in order to enhance safety and enrich travel experiences. Due to the distributed, wireless and open nature of vehicular network, its content delivery faces serious security challenges. The model is asymmetric in that normally the system experiences more loss than profits.

Given the measurement by the model as heuristics, integrity schemes for VANET can be optimized to provide better content delivery. And it operates locally on individual vehicles in a distributed fashion, making it easy to implement.

To further improve the scheme, data-centric approaches, i.

Security in VANETs

Despite the novelty of their work, the researchers of [Azogu12a] only provide sample results of their evaluation model and their proposed integrity scheme. Further simulations as well as cost-performance tradeoff are mentioned as future work to validate the effectiveness of the integrity metrics and the resulting scheme.

Positions of vehicles in VANET are considered Vanet research paper information vulnerable to attackers for abusive purposes. Malicious users can also fake their true positions in order to misbehave. Typical position-based attacks include: Their intuition came from the general need to form the topology for applications like the alert system for congestion.

These applications normally require using all available position detection devices such as radio transceiver and cameras.

As the proverb goes: Under the position detection scheme, a vehicle will regularly broadcast its positional information and receive such information from its neighbors.

Upon receiving positional information from a nearby vehicle, if line of sight is not blocked, the receiver will cross check the accuracy of the information with its own observed eye-device and ear-device data. If there is any discrepancy between during these cross checking, the sender vehicle maybe marked as suspicious and untrustworthy.

This black listing is done locally and therefore is efficient to implement. On top of local positional security, global positional security can be achieved by collecting local blacklists into a centralize database and periodically broadcasting the regional blacklist for the vehicles traveling in that region.

Another way mentioned in [Yan11] to achieve positional security in a larger scope is to exchange blacklists among vehicles in vicinity in an ad-hoc fashion.

The researchers run simulations to investigate the contribution of eye-devices and ear-devices and as a major result, the more type of detecting devices used, the more accurate and secure of the positional information detection and exchange as the cost of more energy consumption and computational as well as communicational overhead.

In addition, active defensive mechanisms like the one proposed in [Prabhakar13] are also essential complements to the passive mechanisms of encryption.

For inputs as given security measures of the VANET, the defensive mechanism adopts game theoretic approaches and is comprised of three stages.

The first stage uses heuristics based on ant colony optimization to identify known and unknown opponents. In the second stage, Nash Equilibrium is employed for selecting the model for a given security problem.

The third stage enables the defensive mechanism to evolve over traffic traces through the game theoretic model from the first stage.Vol.7, No.3, May, Mathematical and Natural Sciences.
