Datagram Transport Layer Security

From Wikipedia, the free encyclopedia

In information technology, the Datagram Transport Layer Security (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 TLS protocol and provides equivalent security guarantees. Datagram semantics of the underlying transport are preserved by the DTLS protocol.

DTLS is defined in RFC 4347.

  • GnuTLS: a free implementation whose licensing is compatible with the GPL.
