A Security Migration Concept for Vehicle-to-X Communication to Allow Long-Term PKI Operation

Applying appropriate security measures in wireless Vehicle-to-X (V2X) communication systems is very important since vehicles and roadside units must trust in information received over this channel. State-of-the-art V2X security solutions are based on Elliptic Curve Cryptography (ECC) using the NIST P-256 curve. For long-term use of such security infrastructure, updatability of security measures as well as cryptographic agility must be ensured.
