Abstract
An integral part of the security solution for a Car-to-X (C2X) communication system is a dedicated public key infrastructure (PKI) that creates the certificates used by the participants and thus establishes an anchor of trust within the system. However, this also raises new questions related to the operation of such a PKI. In this article we discuss these challenges and open issues as well as possible solutions and measures that enhance the security and protect the privacy of C2X participants.
