VANET’s Security, Privacy and Authenticity: A Study

Abstract

. Vehicular Adhoc Network’s (VANET) has gained popularity and focus of research in recent days, due to their distinctive characteristics like fre-quently changing topology with predictable mobility. Much attention of Indus-try and academia both are attracted towards VANETs. Security of data is a crucial aspect of safety related applications of vehicular networks due to their distributed nature and mobility of vehicular ad hoc networks VANETs a critical challenge arises such as collisions of uncoordinated data transmissions and un-stable topologies. This paper presents the basic vehicular ad hoc network’s architecture then shows research issues. This paper provides a survey of research perspective of main aspects of VANETs such as general authentication and security techniques.
