Quizplus · Accepted Answer

A digital certificate system uses third-party CAs (Certificate Authorities) to validate a user's identity. The CA verifies the identity of the individual or organization requesting the digital certificate and then issues the certificate to that entity. This allows for secure digital communication, as the recipient can verify the identity of the sender based on their digital certificate.
