VANET aims to improve safety for all road users. Vehicles exchange safety messages over wireless communication links which are prone to multiple attacks. To enhance the existing security of V2V communications, we propose in this paper a security framework based on vehicles behavior analysis. We define a Hybrid Trust Model (HTM) and a misbehavior detection system (MDS) where a trust metric is assigned...
VANET is an emergent technology with promising future as well as great challenges especially in its security. In this paper, we focus on VANET security frameworks presented in three parts. The first presents an extensive overview of VANET security characteristics and challenges as well as requirements. These requirements should be taken into consideration to enable the implementation of secure VANET...
In this paper, we investigate a security architecture for V2V communication that ensure integrity, confidentiality, anonymity, authenticity and non-repudiation. Based on IEEE 1609.2 Standard, we propose group-based V2V authentication and communication for safety message dissemination with lightweight solution, decentralized via group leaders (GLs), efficient, economical and applicable in real mode...
