Abstract

Vehicular Ad Hoc Network (VANET) is an emerging new technology integrating Ad Hoc network, cellular technology and wireless LAN (WLAN) to achieve vehicle to vehicle and vehicle to infrastructure communication for intelligent transportation systems (ITS). In VANET adopts the public key infrastructure (PKI) and certificate revocation a list (CRL) for their security concerns, but it’s a time consuming checking process. Speedup Message Authentication Protocol for VANET which replaces the time consuming CRL checking process, the revocation check process in SMAP uses a keyed Hash Message Authentication Code (HMAC), where the key used in calculating the HMAC is shared only between nonrevoked On-Board Units (OBU). By performing this one can decreases the message loss ratio and decreases in the delay of transferring message is to be secure and efficient.
