VANETS BASED TRAFFIC SIGNALS CONTROLLING WITH ENHANCED SECURITY MODULE (ESM) IN SMART CITIES

Abstract

VANET is an emerging platform that enables the inter-communication between the vehicles on-road to exchange control and data messages which can be used to take decisive actions to improve user applications such as congestion and traffic monitoring, secure messaging, and general-purpose Internet connectivity. It does not have a fixed infrastructure and uses wireless, multi-hop communication channels with nodes. The main bottlenecks in implementing a rigid security protocol in VANET applications are the absence of coordinated transmission and the fixed network topology in the VANET. The wireless medium requires various safety applications for the passengers. The availability of the pervasive computing infrastructure paves various paths for security vulnerability. Data security is a concern not only in the vehicular network but also in almost all networked systems, especially wireless networks. The network is vulnerable to compromising key pointers in the system such as confidentiality, integrity, authenticity, and privacy (CIAP). Compromising the CIAP parameters will provide access to any level of control over the network. The paper introduced a secure robust framework to establish the network and enable data communication in VANET using an enhanced RSA algorithm for ESM (Enhanced Security Module) model. The optimized LEACH cluster-based routing algorithm is also used to reduce energy consumption as well as to enhance the security of the data.
