DTLS (IETF)

The Datagram Transport Layer Security (DTLS) communications protocol provides communications security for datagram protocols. – Wikipedia

DTLS allows datagram-based applications to communicate in a way that is designed[by whom?] to prevent eavesdropping, tampering, or message forgery. The DTLS protocol is based on the stream-oriented Transport Layer Security (TLS) protocol and is intended to provide similar security guarantees.
