Hi Linda,

Secure Frames are *not* decrypted by the SFU.  The outer HBH encryption is
decrypted by the SFU, but the point of the E2E encryption is that the SFU
does not have the keys.

The document does not claim to save on SFU processing.  For a switching
SFU, the processing should be roughly the same with or without SFrame.

--Richard
