Summary

This chapter summarizes and compares the main characteristics of the three categories of privacy-preserving certificate management schemes: shared certificates, short-lived unique certificates, and group signatures. It provides a summary of their main characteristics. The chapter compares the schemes in several areas: misbehavior detection, misbehavior reporting, and ability to prevent certificate authority (CA) operators from abusing vehicle privacy. It summarizes the remaining technical challenges that should be addressed to make each category of privacy-preserving certificate scheme deployable in a large-scale consumer vehicle network. The characterization and comparison consider the following aspects: privacy levels, signature verification speeds, signature generation speeds, certificate revocation list (CRL) size, difficulty to support misbehavior detection and impact on other protocols layers. The privacy-preserving certificate schemes have a direct and profound impact on how vehicles can report locally detected misbehaviors to global misbehavior detection systems (MDSs).
