Abstract	:	VANET are one of the new promising techniques used to enable communication on roads. Here for VANETs an efficient secrecy maintaining authentication scheme is done .To detect anonymous authentication group signature is used widely used but in previous scheme it suffers from long computation delay in CRL (certificate revocation list) checking. It leads to a high message loss.so they cannot achieve the target of receiving 100 of messages per second.so HMAC is used here to avoid time consuming CRL checking and to ensure the integrity of messages before batch group authentication. To reduce authentication burden each vehicle needs to verify a small number of messages using cooperative message authentication among entities. Hence security and performance analysis shows that our scheme is more efficient in terms of authentication speed by keeping conditional privacy in VANETs. Thus the proposed scheme is analyzed through simulations in NS2 and proved to out performs the existing available techniques.
