Bartosz Zoltak, Master of Science, born 12 Jan 1979.
Graduate of Department of Computer Science and Management of Wroclaw University of Technology, Poland.
Author of the VMPC encryption technology, the privacy protection application VMPCrypt and the Permutrix game.
Author of the scientific paper "VMPC One-Way Function and Stream Cipher"
published on an international cryptography conference
Fast Software Encryption
(FSE 2004).
My trip to the conference was sponsored by the Chancellery of the President of Poland
and by the President of Wroclaw.
Author of many publications on local conferences, seminars and magazines.

More about the VMPC project and the publications:
In 1999 I discovered the VMPC one-way function: f(f(f(x))+1).
It is a simple transformation of permutations which is surprisingly hard to invert.
Why is it interesting?
There is no one-way function in the world - the one-wayness of which can be proved.
Does VMPC have the chance to be the first? From all the one-way-function-candidates VMPC has by far the
simplest structure. Will this simplicity help prove that the function is one-way?
If it was done it would solve the great secret of mathematics, the unsolved for decades problem - is P=NP?
Using the VMPC function I designed the VMPC Stream Cipher - a simple, efficient and secure encryption algorithm.
Along I designed a key management algorithm for this cipher (KSA) and an authenticated encryption scheme (MAC).
This way a the comprehensive VMPC encryption technology was created.
A detailed documentation of the technology can be found in the
Technology section.
Since 2004 I have developed the privacy protection application VMPCrypt.
The application employs the VMPC encryption technology.
One of other applications of the VMPC technology is securing digital press against illegal copying
used by www.e-kiosk.pl.
I was a consultant in the project of applying the technology there.
A few words about the situation of the VMPC project:
Currently I develop the VMPCrypt application, the Permutrix game and conduct research in the project
"VMPC One-Way Function - is P=NP?"
I have a great passion for creating and investigating deeply into problems.
To realize these passions freely - money is needed as everywhere.
