Secure VANET protocol using hierarchical pseudonyms with blind signature

The main objective of deploying Vehicular Ad-hoc Network (VANET) is to reduce the accidents level by providing traffic information to the driver to drive safely. Since VANET supports emergency real-time applications and deals with human life critical information, the security of VANET becomes one of the most critical issues. Numbers of secure VANET protocols have been proposed to solve this issue, but privacy has received less attention. In this paper, we proposed a secure VANET protocol which guarantees privacy and authentication via hierarchical pseudonyms with blind signature. Furthermore, we analyzed our protocol using Scyther Tool for protocol verification. The result shows that our protocol achieved the security claims.
