Abstract
A method at a computing device within an Intelligent Transportation System, the method comprising: determining, at the computing device, whether a short-term certificate is available to sign a message; if the short-term certificate is available, signing the message with a private key associated with the short-term certificate; if the short-term certificate is not available, signing the message with a private key associated with a long-term certificate; and sending the message to a recipient.
Claims20
A method at a computing device installed within a first vehicle in an Intelligent Transportation System, wherein the Intelligent Transportation System is designed to enhance road safety and road efficiency, the method comprising:
- receiving, at the computing device, a message from a second vehicle;
- determining that the message is correctly signed with a private key of a certificate for the second vehicle and that a valid Online Certificate Status Protocol (OCSP) response is appended to the message;
- based on the determining, passing the message to an application layer at the computing device within the first vehicle.
A computing device within an Intelligent Transportation System, the computing device comprising:
- a processor;
- and
- a communications subsystem,
- wherein the computing device is installed within a first vehicle and configured to:
- receive a message from a second vehicle;
- determine that the message is correctly signed with a private key of a certificate for the second vehicle and that a valid Online Certificate Status Protocol (OCSP) response is appended to the message;
- based on the determination, pass the message to an application layer at the computing device.
A non-transitory computer readable medium within an Intelligent Transportation System for storing instruction code, which, when executed by a processor of a computing device installed within a first vehicle cause the computing device to:
- receive a message from a second vehicle;
- determine that the message is correctly signed with a private key of a certificate for the second vehicle and that a valid Online Certificate Status Protocol (OCSP) response is appended to the message;
- based on the determination, pass the message to an application layer at the computing device.
