The new system can change the cyber-addresses
on a network faster than once a second, cloaking
them from all but authorized parties, said Victor
Sheymov -- founder, president, and chief executive
of Invicta Networks.
...
Standard approaches to computer security rely on
encryption, or data scrambling, plus devices such
as firewalls aimed at screening out abnormal traffic
patterns that look threatening.
But any network protected this way is a sitting duck
for a determined hacker, Invicta said. Instead, it
puts the network in cybermotion through a
continuous change of "Internet Protocol" addresses --
the chain of digits underlying the Web to route traffic
to its destination.
The Invicta system uses special cards to link
protected computers to a central control unit. It lets
clients decide how often they wish to vary IP addresses
and specify which applications may be accessed on
their network. The number of IP addresses drawn on may
be in the billions thanks to an artificial increase in
cyberspace, Sheymov said.
I've been pretty busy lately so this could have been discussed on
this mailing list and I could easily have missed it.
Anyway, changing ip addresses once a second would seem to
make it pretty tough for DNS servers to keep up. And even tougher
on maintaining a connection to the host.
