\section{Summary}
% % %
% Theory (probably)
The \acf{ETSI} \acf{ITS} standard architecture contains many identifiers throughout the stack allowing to recognize and track the movement of vehicles and their communication behaviour.
To counter this threat for a user's location privacy, various pseudonym schemes have been proposed. The one proposed for usage with the \ac{ETSI} standards uses asymmetric cryptography and a \acf{PKI}, but lacks a proper definition of important aspects like a detailed pseudonym change strategy, pseudonym resolution resilient against authority misuse or the usage of more advanced cryptographic schemes. But combined with technologies from other research the scheme is feasible to protect user privacy against several proposed attackers.
As many advanced cryptographic schemes are not compatible with the standardsproposed by \ac{ETSI} so far, future work should evaluate whether the standard could be changed to utilize some of these more modern approaches to counter current drawbacks.
