Question

Quizplus · Accepted Answer

A digital certificate system uses third-party Certificate Authorities (CAs) to validate a user's identity. The CA issues a digital certificate that contains the user's public key and other identification information. When a user presents the digital certificate to another party, the other party can verify the user's identity by checking the signature on the certificate using the CA's public key. This provides a secure and trusted way for users to communicate and perform transactions over the internet.
