Secure and Scalable Communication in Vehicle Ad Hoc Networks

Abstract

In this paper the Vehicle Ad Hoc Network (VANET) is examined. As widely agreed VANETs must rely heavily on node-to-node communication while ease of access has to be assured at the same time. Beside the performance ensuring data authentication is another concern in VANETs. In our paper we focus on security aspects for the VANETs that aim to ensure data authentication and allow to ensure data secrecy. Ensuring data secrecy is not a standard feature of the VANETs since usually it is assumed that nodes in the network has to be able to receive all information send over the channel. However we think that it is necessary to ensure security against data eavesdrop and message forgery in some applications (e.g. police pursuits or military convoys).
