Abstract: A vehicular ad hoc network (VANET) uses cars as mobile nodes in a MANET to create a mobile network. For security Vehicular ad hoc networks (VANETs) adopt the Public Key Infrastructure (PKI) and Certificate Revocation Lists (CRLs). In the Public Key Infrastructure system the authentication of a received message is performed by checking if the certificate of the sender is included in the current Certificate Revocation Lists (CRLs) and verifying the authenticity of the certificate and signature of the sender. But it takes more time for CRL checking process. So in order to overcome this problem we use an efficient revocation check process in EMAP uses a keyed Hash Message Authentication Code(HMAC) , where the key used in calculating the HMAC is shared only between non-revoked On-Board Units (OBUs). In addition, EMAP uses a novel probabilistic key distribution which enables non-revoked OBUs to securely share and update a secret key. To conquer computation overhead we introduce the data aggregation using probabilistic checking that can accelerate message verifications and significantly reduce computational overhead while retaining satisfactory security.
Keywords: Vehicular networks, communication security, message authentication, certificate revocation, data aggregation.
