Final answer:
A Certificate Authority (CA) like GlobalSign manages and uses certificates to validate the authenticity and integrity of digital identities. They follow a process called public key infrastructure (PKI) and utilize advanced security protocols to ensure secure certificate issuance and management.
Step-by-step explanation:
A Certificate Authority (CA) like GlobalSign manages and uses certificates to validate the authenticity and integrity of digital identities. The CA follows a process called public key infrastructure (PKI) to issue, revoke, and manage certificates.
When a user or organization applies for a digital certificate, the CA verifies their identity and generates a certificate that includes their public key. This certificate is then digitally signed by the CA, providing a trusted seal of approval. The CA also maintains a Certificate Revocation List (CRL) to revoke certificates if they are compromised or expired.
GlobalSign CA, for example, utilizes advanced security protocols and cryptographic algorithms to secure the certificate issuance and management processes. They store the certificates in a secure repository and employ regular audits to ensure compliance with industry standards like the X.509 specification.
