Since an OCSP response has less data to parse, the client-side libraries that handle it can be less complex than those that handle CRLs. [10] OCSP discloses to the responder that a particular network host used a particular certificate at a particular time. OCSP does not mandate encryption, so other parties may intercept this information. [2]
OCSP stapling is designed to reduce the cost of an OCSP validation, both for the client and the OCSP responder, especially for large sites serving many simultaneous users. However, OCSP stapling supports only one OCSP response at a time, which is insufficient for certificate chains with intermediate CA certs. [26] [27]
In cryptography, X.509 is an International Telecommunication Union (ITU) standard defining the format of public key certificates. [1] X.509 certificates are used in many Internet protocols, including TLS/SSL, which is the basis for HTTPS, [2] the secure protocol for browsing the web.
This article lists protocols, categorized by the nearest layer in the Open Systems Interconnection model.This list is not exclusive to only the OSI protocol family.Many of these protocols are originally based on the Internet Protocol Suite (TCP/IP) and other models and they often do not fit neatly into OSI layers.
An example of a SKA protocol is the Needham–Schroeder protocol. It establishes a session key between two parties on the same network, using a server as a trusted third party. The original Needham–Schroeder protocol is vulnerable to a replay attack. Timestamps and nonces are included to fix this attack.

This is called an "authorization loop" in SPKI terminology, where authorization is integral to its design. [28] This type of PKI is specially useful for making integrations of PKI that do not rely on third parties for certificate authorization, certificate information, etc.; a good example of this is an air-gapped network in an office.
