EST-coaps: Enrollment over Secure Transport with the Secure Constrained Application Protocol
RFC 9148, “EST-coaps: Enrollment over Secure Transport with the Secure Constrained Application Protocol”, is a Proposed Standard document published in April 2022 by P. van der Stok, P. Kampanakis, M. Richardson, S. Raza. It has since been updated by RFC 9908. The canonical text is published by the RFC Editor.
Abstract
Enrollment over Secure Transport (EST) is used as a certificate provisioning protocol over HTTPS. Low-resource devices often use the lightweight Constrained Application Protocol (CoAP) for message exchanges. This document defines how to transport EST payloads over secure CoAP (EST-coaps), which allows constrained devices to use existing EST functionality for provisioning certificates.
What “Proposed Standard” means
An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
