Too Long; Didn't Read

Datagram Transport Layer Security (DTLS) is a protocol used to secure datagram-based communications. DTLS gains the benefits of datagram protocols, too; in particular, the lower overhead and reduced latency. All of the WebRTC related protocols are required to encrypt their communications using DTLS. This includes SCTP, SRTP, STUN, and STUN.Learn more about DTLS at Mozilla's website: http://developer.mozilla.org/en-US/doc/Glossary/DTLS.

Datagram Transport Layer Security (DTLS) is a protocol used to secure datagram-based communications. It's based on the stream-focused Transport Layer Security (TLS), providing a similar level of security. As a datagram protocol, DTLS doesn't guarantee the order of message delivery, or even that messages will be delivered at all. However, DTLS gains the benefits of datagram protocols, too; in particular, the lower overhead and reduced latency.

These features are especially useful for one of the most common areas in which DTLS comes into play: WebRTC. All of the WebRTC related protocols are required to encrypt their communications using DTLS; this includes SCTP, SRTP, and STUN.
