Datagram Transport Layer Security
Encyclopedia
In information technology
, the Datagram Transport Layer Security (DTLS) protocol provides communications privacy for datagram protocols. DTLS allows datagram-based applications to communicate in a way that is designed to prevent eavesdropping, tampering, or message forgery. The DTLS protocol is based on the stream-oriented TLS
protocol and is intended to provide similar security guarantees. The datagram semantics of the underlying transport are preserved by the DTLS protocol — the application will not suffer from the delays associated with stream protocols, but will have to deal with packet reordering, loss of datagram and data larger than a datagram packet size.
DTLS is defined in RFC 4347 for use with UDP
encapsulation and in RFC 5238 for use with DCCP encapsulation.
