VANETs have the potential to dramatically increase road safety by giving drivers more time to react adequately to dangerous situations. To prevent abuse of VANETs, a security infrastructure is needed that ensures security requirements like message integrity, confidentiality, and availability. After giving more details on our security infrastructure we discuss privacy issues and especially the problem of profile generation caused by periodically sent telematics data necessary for many road safety functions. The suggested security infrastructure, mix zones and single-use pseudonyms help to ensure privacy of VANET participants and prevent profile generation while preserving functionality.
