A game app, for example, might not care about secure media and might not want to use SRTP because they have to use a central media server mixer or announcement server or whatever, and don't want to take the hit for SRTP on it. Another example is a website for creating virtual greeting cards, which might use WebRTC to record a personal greeting to go with the virtual card, and might not want to take the hit to secure media to their recording servers. (I don't know if they're popular elsewhere, but in the US these virtual greeting e-card things are popular for sending birthday/anniversary/etc. greetings, and most of them are plaintext HTTP) > > draft-ietf-rtcweb-overview-02 downgraded the SRTP concerns from > mandatory-to-use to mandatory-to-implement. So if it does not > downgrade anymore, a WebRTC implementation (game app, greeting cards > website..) will have to implement SRTP. Hmm... I I don't see any reason to allow insecure calling from one WebRTC client to another. It's a different question whether one should allow insecure calling to legacy clients. > IMHO, if a web service doesn't want to take, or cannot take, the hit > for SRTP, WebRTC is not the appropriate solution for such a service. I'm exceedingly unsympathetic to the claim that SRTP is too slow. This is precisely the claim that was made about TLS for years, but measurements (see Langley and Modadugu's Overclocking SSL talk at Velocity) show that that's not really true. -Ekr
