Ahead of examining RTP's use in WebRTC contexts, It can be helpful to possess a normal concept of what RTP does and would not provide. RTP is a data transport protocol, whose mission is to maneuver data between two endpoints as competently as possible under current circumstances.
Which means even if an attacker managed to Get well a session vital, He's unable to decrypt messages secured with preceding and later on session keys derived through the very same learn essential. (Take note that, obviously, a leaked master key reveals every one of the session keys derived from it.)
The audio transceiver's RTCRtpSender's replaceTrack() technique is utilized to established the outgoing audio track to the initial track of the microphone's audio stream.
This suggests RTP is often — but is just not needed to be — used atop UDP for its overall performance as well as its multiplexing and checksum characteristics.
An RTCRtpTransceiver is actually a pair of just one RTP sender and 1 RTP receiver which share an SDP mid attribute, meaning they share exactly the same SDP media m-line (symbolizing a bidirectional SRTP stream).
RTP alone isn't going to present just about every feasible characteristic, Which is the reason other protocols also are used by WebRTC. A lot of the more noteworthy matters RTP will not include things like:
Apart from the AES cipher, SRTP allows a chance to disable encryption outright, utilizing the so-referred to as null encryption cipher, that may be assumed being an alternate supported cipher. In truth, the null encryption cipher will not accomplish any encryption; the encryption algorithm functions given that the identification functionality, and copies the input stream into the output stream with no variations.
Nevertheless SRTP can easily accommodate new encryption algorithms, the SRTP typical states that new encryption algorithms may perhaps only be introduced through publication of a new companion regular monitor RFC which have to Plainly outline The brand new algorithm.
It's mandatory for this cipher manner to get executed in almost any SRTP-appropriate procedure. As a result, it may be used if the confidentiality ensures ensured by SRTP are certainly not expected, though other SRTP features, such as authentication and information integrity, can be made use of.
During the examples underneath, we'll seek advice from the peer which is popping "keep" manner on and off given that the community peer and the user becoming placed on keep get more info as being the distant peer.
I hope this has offered some insight right into a quite common problem that folks see, why it occurs, and how to take care of it.
As a result, The real key management protocol really should Trade only one grasp critical, all the mandatory session keys are generated by applying The true secret derivation purpose.
Utilization of SRTP or SRTCP is optional in RTP or RTCP purposes; but even when SRTP or SRTCP are employed, all delivered functions (which include encryption and authentication) are optional and can be individually enabled or disabled.
To safeguard towards replay assaults, the receiver maintains the sequence numbers of Earlier received messages, compares them Along with the sequence number in Every single new been given message and admits the new concept provided that it hasn't been previously acquired. This solution relies around the integrity safety to make it difficult to switch the sequence number without having detection.
