The Datagram Transport Layer Security Protocol Version 1.3
RFC 9147, “The Datagram Transport Layer Security Protocol Version 1.3”, is a Proposed Standard document published in April 2022 by E. Rescorla, H. Tschofenig, N. Modadugu. It obsoletes RFC 6347. It has since been updated by RFC 9853. The canonical text is published by the RFC Editor.
Abstract
This document specifies version 1.3 of the Datagram Transport Layer Security (DTLS) protocol. DTLS 1.3 allows client/server applications to communicate over the Internet in a way that is designed to prevent eavesdropping, tampering, and message forgery.
The DTLS 1.3 protocol is based on the Transport Layer Security (TLS) 1.3 protocol and provides equivalent security guarantees with the exception of order protection / non-replayability. Datagram semantics of the underlying transport are preserved by the DTLS protocol.
This document obsoletes RFC 6347.
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.
