RFC 6347: Datagram Transport Layer Security Version 1.2
This RFC has been replaced. Do not implement against it for new work — it was formally obsoleted by RFC 9147.
Current document in this lineage: RFC 9147 — The Datagram Transport Layer Security (DTLS) Protocol Version 1.3
In plain English — editorial summary, not part of the RFC
This document specifies version 1.2 of the Datagram Transport Layer Security (DTLS) protocol. The DTLS protocol provides communications privacy for datagram protocols. The protocol allows client/server applications to communicate in a way that is designed to prevent eavesdropping, tampering, or message forgery. The DTLS protocol is based on the Transport Layer Security (TLS) protocol and provides equivalent security guarantees. Datagram semantics of the underlying transport are preserved by the DTLS protocol. This document updates DTLS 1.0 to work with TLS version 1.2. [STANDARDS-TRACK]
