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.

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.
A computing device within an Intelligent Transportation System, the computing device comprising:
- a processor;
- and
- a communications subsystem,
- wherein the computing device is configured to:
- determine 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.
A computer readable medium for storing instruction code, which, when executed by a processor of a computing device within an Intelligent Transportation System cause the computing device to:
- determine 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.
