Depends on what kind of break you want.  If you want to break into the
connection (ala add/modify/delete traffic in real time), yes a 10 minute
cycle time makes it difficult.  If all you want is the data afterwards (ie:
see the login id and password), then all the 10 minute cycle time does is
force you to do multiple breaks.  But, the login and password are almost
always in the start of a connection, so that is all you need to break.

Outside of quantum crypto and one time keys, nothing is unbreakable.  Its
just a matter of time and resources.  The tricks are to make them
prohibitive, and make sure there is no back door like looking at power
consumption.  And I kind of wonder if there is anything in superstring
theory that could cause problems with quantum crypto.

You are preaching to the choir there - however, my boss is preferring to
believe the consultant's claims that the 10 minute key cycle (communicated
by TLS) makes the system unbreakable.... so it doesn't need to be on a DMZ
and can work "just like they were on the lan"
