Which entity may a certificate authority rely on for validating a certificate signing request (CSR)?

• A. Root authority
• B. Registration authority
• C. Online Certificate Status Protocol
• D. Certificate revocation list

Answer: (B)

A certificate authority (CA) relies on a registration authority (RA) for validating a certificate signing request (CSR). The RA acts as a mediator between the user requesting a certificate and the CA, verifying the user's identity and ensuring that the information provided in the CSR is accurate and legitimate. This process may involve checking various forms of identification or evidence to confirm the entity's identity before the CA issues the corresponding certificate. The registration authority operates under the policies set forth by the CA and ensures that the issuance of certificates is based on a reliable vetting process. Without the RA's validation, the CA cannot confidently issue certificates, which are critical for establishing trust in digital communications. Other options, such as a root authority, are more related to the hierarchy and structure of certificate trust rather than the validation process of a CSR. The Online Certificate Status Protocol (OCSP) is used for checking the revocation status of a certificate after it has been issued, and the certificate revocation list (CRL) is a list of certificates that have been revoked. Neither of these plays a role in the initial validation of the CSR.
