What is it about?
Vehicular ad hoc networks (VANETs) have become increasingly common in recent years due to their critical role in the field of smart transportation by supporting Vehicle-to-Vehicle and Vehicle-to-Infrastructure communication. The security and privacy of VANET are of the utmost importance due to the use of an open wireless communication medium where messages are exchanged in plain text, something which allows attackers to intercept, tamper, replay, and delete them. Hence, there is a high probability that the safety of a VANET-based smart transportation system could be compromised. Nowadays, securing and safeguarding the exchange of messages in VANETs is the focus of many security research teams, as reflected by the number of authentication and privacy schemes that have been proposed. However, these schemes have not fulfilled all aspects of the security and privacy requirements. The present paper is an effort to provide a thorough background on VANETs and their components; various types of attacks on them; and all the security and privacy requirements for authentication and privacy schemes for VANETs. This paper is among the first to provide a comprehensive survey of the existing authentication and privacy schemes and compare them based on all security and privacy requirements, computational and communicational overheads, and the level of resistance to different types of attacks. It also provides a qualitative comparison with the existing surveys. This paper could serve as a guide and reference in the design and development of any new security and privacy techniques for VANETs.

Perspectives
This paper discusses the issues related to the security andprivacy for VANET. Because of the sensitivity of the traffic-related messages being exchanged to and from vehicle nodes,privacy and security are of the utmost importance to theVANET technology. We identify several important securityand privacy requirements for authentication that serve as a fun-damental step to ensuring security in a VANET. Authenticationschemes for VANETs are classified into three types: publickey infrastructure-based security and privacy schemes (PKI-SPS), group signatures-based security and privacy schemes(GP-SPS), and identity-based security and privacy schemes(ID-SPS). We surveys and compares all the schemes in thethree categories in terms of their strengths and weaknesses,fulfillment of the security and privacy requirements, level ofattack resistance, as well as their performance (computationaland communicational overheads). The security and the effi-ciency of the existing authentication schemes for VANETs areevaluated and presented to assist researchers and developers inidentifying and distinguishing key features of the security andprivacy of a VANET. It is our hope that this paper can serve asa guide and reference in the research, design and developmentof any new security and privacy techniques for VANETs inthe future
