In the context of digital certificates, the Registration Authority (RA) is responsible for verifying the identity of entities requesting a certificate before the Certificate Authority (CA) issues it. The RA acts as a verifier for the CA, ensuring that the entity requesting the certificate is who they claim to be. This process is crucial for maintaining trust within a digital environment, as it prevents the issuance of certificates to fraudulent or unauthorized entities.

References: The role of the Registration Authority in the verification process is outlined in the EC-Council’s Certified Network Defender (CND) curriculum, which covers the essential concepts of network security, including the management and issuance of digital certificates.
