Abstract
The present invention advantageously provides techniques to solve problems with combinatorial anonymous certificate management by addressing critical issues concerning its feasibility, scalability, and performance. Methods and procedures to manage IEEE 1609.2 anonymous and identifying cryptographic keys and certificates in the Vehicle Infrastructure Integration (VII) system are presented, along with methods for management of identifying and anonymous certificates in a partitioned Certificate Authority architecture designed to enhance vehicle privacy. Novel methods for vehicles to dynamically change an anonymous certificate for use while maintaining vehicle privacy are given. Refinements to basic combinatorial schemes are presented including probabilistic key replacement, rekey counter decrement, dynamic rekey threshold, geographic attack isolation and proofs of geographic position.
