[liberationtech] security aspects of OpenQwaq

OpenQwaq is potentially a useful tool for collaboration, 
especially multimedia (webcam streaming to avatar face,
audio (best with USB headset) with ability to
instantiate rooms) -- I've seen it scale to
groups or 50+ partipants. Collaborative editing is 
available.

Disclosure: no commercial relation to 3D ICC, just a
happy user of their hosted services.

Hi Eugen,

 

OpenQwaq uses ARC4 for encryption.  All data end to end is encrypted over a
single port connection. 

 

3D ICC's Immersive Terf T uses SSL for encryption.  It's basically the same
model but we've improved it for, security, performance and reliability.  

 

All encrypted traffic is susceptible to MITM.  SSL helps this considerably
by using public certificate authorities to verify the certificates.  The
trick is to ensure that your DNS is accurate and that all certificates are
verified.  

 

The open source version of OpenQwaq on the other hand is encrypted without
certificates.  

 

In either case MITM would leave some significant performance foot prints
(this could be improved using hardware) and it would take some engineering
to understand our overlay network protocols to make the data useful for an
attacker.

 

Are you safe from hackers?  Yes I would say that MITM is very unlikey for
both OpenQwaq and TerfT.

 

Are you safe from Governments?  No.  Unlimited access to resources and
direct internet filtering could in theory attack the connection using MITM
by subverting DNS, using hardware proxies, and forwarding to the server.

 

How safe is it?  We have been reviewed by the Federal Reserve Bank in New
York and were allowed to have our software installed internally.  We have
been used by every branch of the military (except the Marines, why I have no
idea, except maybe because the Navy used it).  We have had significant
pentration testing done by some of the largest financial institutions and
corporations in the world and have passed.   I would say that this puts us
in the upper categories of safeness but still below top secret grade*.

 

Hope that helps.

 

All the best,
