<font style="font-style: normal; font-weight: normal; text-decoration: none; vertical-align: baseline;">Security mechanisms for ITS consist of a number of parts.

<font style="font-style: normal; font-weight: normal; text-decoration: none; vertical-align: baseline;">The present document intends to provide such a format definition.
