name: ACME
full_form: Automatic Certificate Management Environment
context: ACME can be implemented in multiple ways depending on the trust model network participants wish to use and which aspects of the 5G infrastructure will use ACME based certificates. IETF RFC 8555 [23] is extensible to many use cases, such as the TNAuthList profile [27]. ACME architectural elements, as depicted in Figure 6.16.2.1-1, include an ACME client (Client) and an ACME server (Server). These map directly to the CEMAF reference point architecture illustrated in Figure 6.1.2.2-1. The ACME client maps to the NF, and the ACME server maps to the CeEF and to the CeMF. The same ACME server can be used for both the CeEF and CeMF, or different ACME servers could be used. Figure 6.16.2.1-1 Information covered by request signatures Certificate Issuance
description: The Automatic Certificate Management Environment (ACME) is a protocol for automating the management of certificates, enabling secure communication between network elements and facilitating the issuance of certificates for various use cases within the 5G infrastructure.
explanation: ACME defines rules for data transmission and communication between clients and servers involved in certificate management within the 5G network, aligning with the definition of a protocol.
