Just before examining RTP's use in WebRTC contexts, It can be helpful to possess a normal concept of what RTP does and does not provide. RTP is an information transportation protocol, whose mission is to maneuver knowledge in between two endpoints as effectively as possible underneath present-day conditions.
Since the streams for an RTCPeerConnection are executed applying RTP plus the interfaces above, it is possible to take advantage of the accessibility this gives you on the internals of streams to generate changes.
Every RTCPeerConnection has approaches which give access to the listing of RTP transports that assistance the peer relationship. These correspond to the following 3 varieties of transportation supported by RTCPeerConnection:
The very fact that RTCP is defined in precisely the same RFC as RTP is actually a clue as to only how intently-interrelated these two protocols are.
The audio transceiver's way is about to "sendrecv", indicating that it should really return to equally sending and receiving streamed audio, in place of only sending.
A essential derivation perform is utilized to derive the different keys Employed in a copyright context (SRTP and SRTCP encryption keys and salts, SRTP and SRTCP authentication keys) from a single solitary learn important in a very cryptographically secure way.
Moreover the AES cipher, SRTP permits the chance to disable encryption outright, using the so-known as null encryption cipher, which may be assumed being an alternate supported cipher. In actual fact, the null encryption cipher would not conduct any encryption; the encryption algorithm capabilities since the id operate, and copies the enter stream into the output stream with none alterations.
The above mentioned-stated encryption algorithms do not alone safe concept integrity, an attacker won't be in a position to decrypt data but might be able to forge or replay previously transmitted facts. Therefore the SRTP common also supplies the suggests to safe the integrity of information and basic safety from replay.
To authenticate the information and secure its integrity, the HMAC-SHA1 algorithm[one] is applied. This creates a one hundred sixty-bit outcome, which is then truncated to eighty or 32 bits to become the authentication tag appended to every packet. The website HMAC is calculated about the packet payload and product through the packet header, including the packet sequence variety.
Media is not really resistant to NAT as many people most likely know. Just like SIP signaling the IP deal with and port for where by media should be despatched to can be exchanged in SDP inside the “c=” and “m=” strains. Identical to Along with the Call header a device might not place the correct information and facts in resulting in media being sent to the wrong target.
Substitute the audio transceiver's RTCRtpSender's track with null, that means no track. This stops sending audio to the transceiver.
The transceiver's route is set to "sendrecv", indicating that it need to resume both sending and getting audio.
Utilization of SRTP or SRTCP is optional in RTP or RTCP purposes; but even though SRTP or SRTCP are applied, all provided functions (for instance encryption and authentication) are optional and might be separately enabled or disabled.
He is a self-taught programmer who believes in finding the equilibrium between performing issues the way in which they should be done and doing what is true to the individuals utilizing the application. In his spare time he enjoys smashing fax equipment. See All of Author's Posts
You will also find other strategies to barter the SRTP keys. There are various sellers which offer products that use the SDES crucial exchange system.
