How is the key distribution secure?

I know we can see a shared key on one of the configuraiton window of
VIC in case video streams are encrypted.  The key has to be
transmitted from the venue server to an AG client and the AG client to
VIC and RAT.  I suppose in both cases the key is encrypted because it
is transmitted over a https connection.  Is this correct?
