In this paper, we assumed that every vehicle is equipped with a wireless communication unit and every intersection has a wireless unit called the Intersection Traffic Controller (ITC). All vehicles near an intersection communicate with the corresponding ITC to send their dynamic information such as speed, acceleration, lane number, road number, and distance from the intersection. Though the wireless technology will be a viable technology for developing intersection collision warning systems, it is subject to various types of security attacks unless the system is properly designed. This paper presents a secure wireless protocol for intersection collision warning systems with a detailed bit level description of the protocol. The security is maintained using a chain of digital certificates issued by various federal and state organizations. The vehicles validate the certificate of the ITC using the public key issued by a federal organization, such as the US Department of Transportation. This paper also presents the performance analysis of the intersection collision warning system. Printed in USA
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
