Security Challenges in MANET-based Telematics Environments

Over the next couple of years the use of ad hoc networks especially for telematics applications will increase a lot to provide new types of services to passengers within the vehicle. Since the ad hoc environment is very vulnerable to a multitude of different attacks, new methods of securing these network environments have to be developed. In this paper the vulnerabilities of ad hoc networks are pointed out concentrating on the vehicular environment as one possible example. Several telematics use cases and their security requirements are presented. Further, some attacks are described that can be applied within ad hoc networks. With LKN-ASF one possible solution for securing a gateway-supported mobile ad hoc network is presented and evaluated. The paper concludes with an outlook on possible future work.
