Abstract
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.
Claims19
A method at an Intelligent Transportation System (ITS) Transmitting Entity, the method comprising:
- generating an ITS message at the ITS Transmitting Entity;
- augmenting the ITS message with an Integrity Report generated by an integrity detection function internally within the ITS Transmitting Entity to create an augmented ITS message, the integrity detection function checking a cybersecurity posture of a transmitter of the ITS transmitting entity, wherein the Integrity Report is generated by performing, by the integrity detection function at the ITS transmitting entity, an integrity check of ITS Transmitting Entity;
- 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.
An Intelligent Transportation System (ITS) Transmitting Entity, the ITS Transmitting Entity comprising:
- a processor;
- a memory;
- and
- a communications subsystem,
- wherein the memory storing instructions when executed by the processor cause the ITS Transmitting Entity to:
- generate, using the processor, an ITS message at the ITS Transmitting Entity;
- augment, using the processor, the ITS message with an Integrity Report generated by an integrity detection function internally within the ITS Transmitting Entity to create an augmented ITS message, the integrity detection function checking a cybersecurity posture of a transmitter of the ITS transmitting entity, wherein the Integrity Report is generated by performing, by the integrity detection function at the ITS transmitting entity, an integrity check of ITS Transmitting Entity;
- sign, using the processor, 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
- send, using the communications subsystem, the signed, augmented ITS message to an ITS Receiving Entity.
A non-transitory computer readable medium for storing instruction code which, when executed by a processor of an Intelligent Transportation System (ITS) Transmitting Entity cause the ITS Transmitting Entity to:
- generate an ITS message at the ITS Transmitting Entity;
- augment the ITS message with an Integrity Report generated by an integrity detection function internally within the ITS Transmitting Entity to create an augmented ITS message, the integrity detection function checking a cybersecurity posture of a transmitter of the ITS transmitting entity, wherein the Integrity Report is generated by performing, by the integrity detection function at the ITS transmitting entity, an integrity check of ITS Transmitting Entity;
- sign 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
- send the signed, augmented ITS message to an ITS Receiving Entity.
