摘要：Vehicular Ad-Hoc Network (VANET) is a technology
that has been recently designed as one of the emerging future
communications systems, a critical specialist used to support
Intelligent Transportation Systems (ITS) by implementing a wide
range of automotive applications and services. The primary
objectives of VANET are to improve road safety and driving
conditions. In addition, it supply many services including toll
payment services, navigation, warning messages, congestion
avoidance, alarm signals, and convenient internet access. The
vehicle networks facing many different challenges and attacks
due to lack of permanent infrastructure and high mobility. To
maintain the network carefully against attackers, the security
design of VANET must ensure integrity, authentication and confidentiality
services. Moreover, as that network is very dynamic,
making it a unique type of network, it is important to consider
how this affects network security. Hence, this paper discusses the
components and characteristics of vehicular networks. It has also
presents survey of security challenges facing vehicle networks and
security requirements. Moreover, it summarizes and analyses the
possible attacks and a set of security weaknesses exist in VANET.
