CRL repository: Required; the repository can be either a centralized repository in DMZ, or it can be located within each local CA. Distributed model (bridge CA): Certificate repository: Required; in IKE authentication phase each SEG needs access to intermediary certificates (i.e. cross-certificates of peer CAs and the Bridge CA) if they are not sent within the certificate payload.

description: A DeMilitarized Zone (DMZ) is a physically or logically separated section of a network designed to provide an additional layer of security. It acts as a buffer between public-facing networks and internal private networks. In the context of 3GPP TS 33.810, it refers to a centralized location for storing certificates and Certificate Revocation Lists (CRLs), which can be situated within the DMZ or within each local Certificate Authority (CA).
explanation: The concept of a DMZ is classified as a Network Segment because it represents a distinct and isolated part of a network, specifically designed to enhance security by separating public and private network traffic.
