Abstract
In a vehicle-to-everything (V2X) technology environment, systems and methods are provided for extending the distribution of activation codes (ACs) in an Activation Codes for Pseudonym Certificates (ACPC) system, in a privacy-preserving manner, to a unicast mode of communication. In this unicast ACPC (uACPC), in some embodiments, the ACs are distributed by the back-end system via a unicast channel upon the receipt of the vehicle's direct request for its respective ACs. In some embodiments, uACPC can leverage edge computing architecture for low latency delivery of certificate revocation lists (CRLs) and higher availability for the distribution of ACs.
