Abstract

Concepts and technologies disclosed herein are directed to vehicle-to-everything (“V2X”) certificate management. According to one aspect of the concepts and technologies disclosed herein, a system can receive a CRL from a security credential management (“SCM”) system. The CRL can identify one or more certificates that have been determined to be invalid, such as when the certificate(s) has expired. The certificate(s) can be utilized by a vehicle for secure communications, including vehicle-to-vehicle (“V2V”) and vehicle-to-infrastructure (“V2I”) (collectively V2X). The system can format the CRL as a cell broadcast message. The system can then create a cell broadcast request directed to a cell broadcast center (“CBC”). The cell broadcast request can include the CRL formatted as the cell broadcast message. The system can send the cell broadcast request to the CBC to instruct the CBC to broadcast the CRL as the cell broadcast message.
