A set of certificate management methods designed to significantly reduce or eliminate reliance on infrastructure network connectivity after vehicles are sold uses techniques to support certificate management operations in order to reduce the frequency which vehicles need to communicate with the Certificate Authorities (CAs) and the amount of data that needs to be exchanged between vehicles and the CA. These methods include, for example, approaches to use one-way communications and vehicle-to-vehicle (V2V) communications to replace expired certificates, approaches to use one-way communications and V2V communications to replace revoked certificates, and use of a small subset of vehicles as proxies to help retrieve and distribute Certificate Revocation Lists (CRLs) and replacement certificates. The combination of these techniques leads to solutions that can eliminate the need for roadside infrastructure networks completely.
A method for using one-way communications to support Public Key Infrastructure (PKI) operations including for distributing certificate revocation lists (CRL), replacing expired certificates, and replacing revoked certificates, comprising one-way infrastructure-to-vehicle communication.
A method for using CRL seeding to distribute CRL to vehicles, comprising the steps of:
A method for using one-way radio or satellite broadcast to distribute CRLs to vehicles, comprising the steps of:
A method for using Mobile Infrastructure Access Points to distribute CRLs and replacement certificates to vehicles comprising the steps of:
A method for using one-way infrastructure-to-vehicle communications to replace expired certificates comprising:
A method for using one-way infrastructure-to-vehicle communications and Symmetrically Encrypted Replacement Certificate List Certificate Decryption Key Utility (CDK) to replace revoked certificates where replacement certificates are placed on the RCRL by the CA and encrypted with a symmetric key.
A system for using one-way communications to support Public Key Infrastructure (PKI) operations comprising:
