full_form: Public Key Infrastructure
context: to an authentication request. Class AVP: The Class AVP is used to by Diameter servers to return state information to the access device. Event-Timestamp AVP: The Event-Timestamp may be included in an Accounting-Request and Accounting-Answer messages to record the time that the reported event occurred, in seconds since January 1, 1900 00:00 UTC. RFC 3280 [42] profiles the format and semantics of certificates and Certificate Revocation Lists (CRLs) for the Internet PKI. The users of certificates will operate in a wide range of environments with respect to their communication topology, especially users of secure electronic mail. This profile supports users without high bandwidth, real-time IP connectivity, or high connection availability. The following figure gives an overview over the basic building blocks of IETF's PKI infrastructure. Figure 5.1.2.5.2.1: PKI Entities defined by IETF [42] The following paragraphs present the profile for public key certificates according to RFC 3280 [42]
description: Public Key Infrastructure (PKI) is a set of standards and protocols governing the use of public-key cryptography in telecommunications. It enables the creation, management, and deployment of public-private key pairs for encrypting and decrypting data, facilitating secure communication and authentication.
explanation: The description emphasizes PKI's role as a set of standards and protocols used in telecommunications for secure communication and authentication through public-key cryptography. This clearly classifies it as a technology.
