The benefit of the Online Certificate Status Protocol (OCSP) is that it allows a device to query whether a single certificate is revoked or not. OCSP provides a real-time mechanism for checking the revocation status of an individual certificate, enabling devices to verify the validity of certificates quickly and efficiently.
1.Certificate Status Query: OCSP enables devices to send a query to an OCSP responder to check the revocation status of a specific certificate.
2.Real-Time Verification: This protocol offers real-time responses, ensuring that the most up-to-date status of the certificate is obtained.
3.Efficiency: OCSP is more efficient than downloading an entire Certificate Revocation List (CRL), as it only queries the status of one certificate at a time.
