What is the main purpose of an Enhanced Trusted Agent after notification of a broken token?

The main purpose of an Enhanced Trusted Agent after notification of a broken token is to replace a broken token within 24 hours. When a user reports that their cryptographic token is broken or compromised, it is critical to ensure that they receive a new token promptly to maintain the security and integrity of the PKI system. The Enhanced Trusted Agent plays a pivotal role in facilitating this process efficiently, reducing potential security risks, and minimizing downtime for the user who relies on the token for authentication and access to secure resources.

The urgency in replacing the token within a specified timeframe, such as 24 hours, underscores the importance of maintaining operational continuity and the security posture of the Army's PKI. This swift response helps to avoid security vulnerabilities that could arise from prolonged reliance on a broken or unusable token.

The other options focus on tasks that, while important within the context of PKI management, do not directly address the immediate need for token replacement in response to a report of a broken token.
