Security and privacy enhancing technologies are an essential feature for the intelligent transportation system (ITS) deployment. As security system introduces generally an overhead, the test and evaluation of a defined security solution is as important as its design. In this context, the PRESERVE project aims to design, implement and test a secure and scalable security system for ITS. In this paper, the authors focus on the PRESERVE security tests and precisely the joint trial tests with the French Score@F FOT. The authors present the test cases of PRESERVE VSS integrated with Score@F FOT system and evaluated performance indicators. This will be the first paper describing PRESERVE test cases and Score@F platforms integrating security solution.
