In a Public Key Infrastructure (PKI), what is the main responsibility of a Registration Authority (RA)?
Issuing digital certificates
Verifying the identity of certificate requestors
Generating public-private key pairs
Revoking compromised certificates
The correct answer is Verifying the identity of certificate requestors. In a Public Key Infrastructure (PKI), the Registration Authority (RA) is primarily responsible for verifying the identity of entities requesting certificates. The RA performs the authentication and validation of certificate requestors before forwarding the request to the Certificate Authority (CA).
Issuing digital certificates is incorrect because this is the responsibility of the Certificate Authority (CA), not the RA.
Generating public-private key pairs is incorrect because these are typically generated by the end entity requesting the certificate, not by the RA.
Revoking compromised certificates is incorrect because while the RA may receive certificate revocation requests, the actual revocation is typically performed by the CA.
