ASurvey on Secure Safety Applications in VANET

Abstract

Abstract—Providing an efficient secure authentication scheme in safety applications in Vehicular Ad-hoc Networks (VANETs) is a challenging issue. This is because these applications need to react to their messages, in a timely manner, before their respective deadlines. Preserving the privacy of the exchanged messages is also important since these messages include sensitive information, such as geographical locations. In this paper, we review the existing schemes that aim to meet the requirements of security and privacy. Then, we specify these requirements with a view to design an efficient scheme for secure real-time applications in VANET environments.
