Method and system for reduced V2X receiver processing load using certificates

A method at an Intelligent Transportation System (ITS) Transmitting Entity, the method including: generating an ITS message; augmenting the ITS message with an Integrity Report generated by an integrity detection function at the ITS Transmitting Entity to create an augmented ITS message; signing the augmented ITS message with an Authorization Certificate or Ticket, the Authorization Certificate or Ticket including an assurance indication from an Audit Certificate Authority for the integrity detection function; and sending the signed, augmented ITS message to an ITS Receiving Entity.

Method and system for establishing trust for a cybersecurity posture of a V2X entity
