Can an end user use an intermediary for authentication without prior approval from the RA/LRA?

The correct answer states that an end user must submit a prior request for authentication through an intermediary. This is important because the Registration Authority (RA) or Local Registration Authority (LRA) is responsible for verifying the identity of individuals requesting digital certificates. Allowing direct use of an intermediary without prior approval could lead to security risks, as it may undermine the integrity of the authentication process.

The RA/LRA ensures that all authentication actions are performed according to established procedures and policies, which are designed to maintain the security and trustworthiness of the PKI environment. If users were allowed to use intermediaries independently, it could create vulnerabilities for unauthorized access or identity fraud.

By requiring a prior request, the RA/LRA can assess the situation and determine whether the use of an intermediary meets the organization's security requirements or if it poses potential risks. This structured approach helps to ensure that all authentication processes are controlled and compliant with the organization's policies and standards, thereby safeguarding the entire PKI infrastructure.
