Lightweight Certificate Management Protocol Profile

Overview

RFC 9483, “Lightweight Certificate Management Protocol Profile”, is a Proposed Standard document published in November 2023 by H. Brockhaus, D. von Oheimb, S. Fries. The canonical text is published by the RFC Editor.

Abstract

This document aims at simple, interoperable, and automated PKI management operations covering typical use cases of industrial and Internet of Things (IoT) scenarios. This is achieved by profiling the Certificate Management Protocol (CMP), the related Certificate Request Message Format (CRMF), and transfer based on HTTP or Constrained Application Protocol (CoAP) in a succinct but sufficiently detailed and self-contained way. To make secure certificate management for simple scenarios and constrained devices as lightweight as possible, only the most crucial types of operations and options are specified as mandatory. More specialized or complex use cases are supported with optional features.
