Could you please explain that?

Zultrax supports two networks, Zepp and Gnutella. This feature is -of course - only available on Zepp. On that protocol Zultrax is the only available client. Zultrax hides which communication is going to which IP and on which IP files are found.

If one manages on some kind of way to connect to ZEPP and discramble the communication one might be possible to make that information visible. That is what we try to prevent.

Based on the characteristics of the communication one node calculates two complex numbers and sends one to the other. The other replies with the second number. If that does not match it is not using the proper algoritm and one is apperently trying to enter the network not using Zultrax.

In that case an intruder is detected. The intruder could be trying to figure out that algorithm without having to decompile zultrax and we make his attempt easy by sending an error message every time he is wrong.

So, we don't. We keep the connection alive and make sure that all information sent to him is garbage. That garbage can be created to answer queries with actuall found files but combined with the wrong IP's. Of course ' search results' being given by this intruder will be just dropped.

As a result the intruder will be given no information helping him in his attempt to hack stuff instead he will have hard time to detect if he is receiving garbage or not.

The used algorithm is dynamically and the garbage not just garbage but made as realistic as possible and in a low percentage of the cases it is not garbage, it is real.

Finally the goal of all this is to increase levels of privacy a little.
