Abstract—Hacking and threats are increasing with the enhanced population of wireless traffic. Authentication of correct mobile nodes in Vehicular Ad Hoc Network is an extremely challenging issue to the researchers. Vehicular Ad Hoc Network (VANET) is one of the wireless ad hoc networks which are based on IEEE 802.11 wireless standard enabling vehicle to vehicle and vehicle to roadside communications through air interface. Information (voice, message, data, image etc) are routed in the cells or networks, any node or person can hack or tamper the information. In this paper, a mutual authentication technique is proposed which verifies the authenticity of the calling and the called subscribers (nodes or vehicle drivers) as well as the calling node with the network by calling subscriber’s password, SIM and biometric properties of the calling subscriber. Two biometric parameters are used in which one biometric parameter is stored in his own node and the other biometric parameter taken as frequency of Flipping or Clapping sound of each subscriber, called certified document (CD), is stored at the other nodes or the server (PDSN or MSC). An algorithm is developed by these four entities to check this authentication process, named four entities mutual authentication technique for Vehicular Ad Hoc Network (VANET).
