What type of message does a CONAUTH send to provide effective and supersession information?

The CONAUTH sends a STATUS message to provide effective and supersession information because this type of communication is specifically designed to update users on the current status of cryptographic materials and any changes to their availability or effectiveness. A STATUS message serves to confirm whether a particular component or item is still valid and in use, or if it has been superseded by something new. This ensures that personnel have the most current information necessary for security and operational protocols.

In contrast, the other types of messages serve different purposes. An UPDATE message typically conveys changes or new information, while an ALERT message is used to indicate urgent situations that may require immediate attention. A NOTIFICATION message is generally used for general information dissemination. Therefore, the nature of the STATUS message aligns directly with the needs of effective communication regarding current and superseded security measures.
