True or False: The TA needs to validate the subscriber's identity in person for token issuance.

The statement is true because the Trusted Agent (TA) plays a crucial role in the verification process of a subscriber's identity before issuing a token. This in-person validation helps ensure that the person receiving the token is indeed who they claim to be, which is essential for maintaining the security and integrity of the Public Key Infrastructure (PKI). Face-to-face identity verification minimizes the risk of identity theft or fraudulent token issuance, reinforcing the trust in the system.

In the context of PKI, proper identity validation is aligned with security protocols, and the TA is specifically trained to handle this process effectively. This prevents unauthorized access and safeguards sensitive information associated with the user's cryptographic identity. Thus, in-person validation is a standard requirement for issuing tokens to ensure compliance with the PKI framework and security best practices.
