Security of C-ITS messages: A practical solution the ISE project demonstrator

Abstract

Cooperative Intelligent Transport Systems (C-ITS) offer innovative ways of wireless communication between Intelligent Transport Systems (ITS) stations and ITS road-side stations. They favour the development of ITS applications to improve traffic management, road safety, mobility and other comfort services. C-ITS systems have to guarantee communication security, especially in heterogeneous network environments. Safety critical applications require authentication to avoid attackers to send spoofed or reforged information, nevertheless, cars and drivers privacy must be maintained. We present a demonstration of the C-ITS security management infrastructure of the ITS-Security (ISE) project [1]. Through our demonstrator we show how ISE provides message authentication without violating cars and drivers privacy. Our demonstrator allows the public to run an attack scenario with and without the ISE security system, making evident importance of securing ITS communications.
