Title	Intelligent Transport Systems (ITS); Security; Pre-standardization study on pseudonym change management Pseudonym change strategies
Scope and Field of Application	To realize an overview of the relevant pseudonym change strategies and solutions suitable for C-ITS (pseudonymous authentication based on PKI). To provide a comparison of the efficiency and the estimated performances of different pseudonym change strategies and identify relevant strategies to support various ITS-S profiles. The change rate of ITS-S credentials is a crucial parameter for protection of privacy. However these strategies may have different impacts on the level of privacy, on communication overhead, storage and computation, as well as on costs. As pseudonym ID changes must be consistent across layers, pseudonym changes also have impact on C-ITS protocol stack performances (i.e. all stack layers has to change there IDs). To make recommendations for further specifications for existing standards revision or new standard development.
