What is a benefit of Online Certificate Status Protocol (OCSP)?

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.

Reference: Documentation on certificate management and OCSP describes how OCSP works and its

advantages in providing real-time certificate status checks compared to traditional CRLs.
