Vehicular networks play an important role in current intelligent transportation networks and have gained much attention from academia and industry. Vehicular networks can be enhanced by Long Term Evolution-Vehicle (LTE-V) technology, which has been defined in a series of standards by the 3rd Generation Partnership Project (3GPP). LTE-V technology is a systematic and integrated V2X solution. To guarantee secure LTE-V communication, security and privacy issues must be addressed before the network is deployed. The present study aims to improve the security functionality of vehicular LTE networks by proposing an efficient and secure ID-based message authentication scheme for vehicular networks, named the ESMAV. We demonstrate its ability to simultaneously support both mutual authentication and privacy protection. In addition, the ESMAV exhibit better performance in terms of overhead computation, communication cost, and security functions, which includes privacy preservation and non-frameability.

These operate in different frequency bands provide varying communication ranges, data rates, channel bandwidths, and mobility supporting capability features [2]. Traffic accidents have caused billions of dollars' worth in losses as compared to health-related incidents. Therefore, the enhancement and fusion of vehicular wireless network communication technology between vehicles, pedestrians, infrastructure, and the environment can ultimately improve traffic safety and efficiency [3].In order to accommodate for increasing mobile data transmission demands and new multimedia applications, 3GPP have characterized long-term evolution (LTE) and LTE-Advanced (LTE-A) technologies as emerging mobile communication technologies as next generation broadband mobile wireless networks [4]. LTE technologies exhibit high data rates, high penetration rates, comprehensive QoS supporting, and extended coverage. These technologies possess natural benefits to provide V2I communications. Three LTE application challenges are observed in V2V communications [5]. Firstly, the centralized architecture lacks V2V communication support. Secondly, it requires a better capacity to support the heavy load that is strongly generated by periodic messages. Thirdly, LTE applications potentially penalize the delivery of traditional applications. A complementary relationship between cellular and ad-hoc communication technologies is suggested rather than one that focuses on competition. The extension of LTE technologies with direct communication capabilities between vehicles is a promising and possibly integrated vehicle-to-everything (V2X) solution [6].Many international companies, including Huawei, Qualcomm, Ericsson, and Google have researched vehicular long-term evolution-vehicle (LTE-V) technologies. LTE-V is a fast deployment technology that uses the legacy LTE network. However, one chipset, namely the LTE ...
