What is the primary function of Trusted Agents (TAs)?

• A. Provide the interface between the Army RA and Subscribers/PKI Sponsors
• B. Manage network hardware
• C. Conduct security audits
• D. Develop PKI policies

Answer: (A)

Trusted Agents act as the bridge between the Army’s Registration Authority and the people or organizations requesting certificates. Their main role is to facilitate enrollment and certificate provisioning by validating identities, collecting the necessary information, and routing requests between subscribers or PKI sponsors and the RA. This separation keeps the RA focused on verification while the TA handles the day-to-day interactions with applicants and sponsors, ensuring enrollment procedures align with policy. They’re not responsible for managing network hardware, conducting security audits, or developing PKI policies, which are tasks for IT operations, audit teams, and policy authors, respectively. For example, a user seeking a certificate works with a TA who verifies the sponsor’s authority and the user’s identity, forwards the validated enrollment to the RA for issuance, and then delivers the certificate back through the TA.
