This chapter describes new public key infrastructure (PKI) architectures that prevent any individual certificate authority (CA) from having sufficient information to track vehicles based on certificates. It first discusses the basic idea and the baseline architecture, with its enabling protocol message flow and message processing procedure. The chapter then describes enhancements to the baseline architecture and protocol to support shared certificates, unlinked short‐lived certificates, anonymously linked short‐lived certificates, and to allocate batches of unlinked or anonymously linked short‐lived certificates. To acquire privacy‐preserving certificates, vehicles can interact with the Authorizing CA or the Assigning CA, but not necessarily both. Allocating and revoking anonymously linked certificates or batches of certificates require additional processing in order to prevent each individual CA from knowing which certificates have been assigned to which vehicles.
