DTLS

The Datagram Transport Layer Security Protocol (DTLS) provides data security for protocols using datagrams . DTLS allows data-based communications applications to communicate in a secure way, preventing interception, eavesdropping, tampering, without compromising data integrity protection or falsifying message content. DTLS is based on the Transport Layer Security ( TLS ) stream protocol and thus provides the necessary security guarantees. The datagram semantics of the underlying transport protocol is inherited by the DTLS protocol — its application will not suffer from streaming delays, but must take into account the costs of packet reordering, loss of datagrams, as well as excessive data size larger than the datagram size of the packet.

The use of DTLS is defined in RFC 6347 documents for use with User Datagram Protocol ( UDP ), in RFC 5238 for use with Datagram Congestion Control Protocol ( DCCP ), in RFC 6083 for use of encapsulation in Stream Control Transmission Protocol ( SCTP ), and also in RFC 5764 for use in the Secure Real-time Transport Protocol ( SRTP ), usually recently used in the DTLS-SRTP bundle in the Secure Real-Time Transport Control Protocol ( SRTCP ) working documents. ^[one]
