Glossary of Security Terms: Datagram Transport Layer Security

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.
