Datagram Transport Layer Security

Lab ready Full lab

Datagram Transport Layer Security adapts TLS to unreliable transports with retransmission, explicit sequence numbers, and record epochs. It is the basis for DTLS-SRTP keying in WebRTC and for securing CoAP/UDP apps. Loss during handshake is expected and must be tolerated.
