It can provide TLS Similar security protection .DTLS Commonly used in streaming media .
DTLS And TLS
DTLS is similar to TLS intentionally except that DTLS has to solve two problems: packet lost and reordering. DTLS implements
packet retransmission
assigning sequence number within the handshake
replay detection.
DTLS be based on UDP Agreed ,OpenSSL Realized DTLS
stay WebRTC Use in DTLS There are two parts to it :
Datachannel Data channel . stay Datachannel In the data channel ,WebRTC Fully using the DTLS To negotiate and encrypt and decrypt
MediaChannel Media channel . In the media channel WebRTC Use SRTP To encrypt and decrypt data ,DTLS Is only used for key exchange ,RTP/RTCP For the sake of compatibility with historical equipment , Entirely by SRTP To achieve .
