The answer to known problems of the
One-time pad.

Binary projection

Quantum, post-post-quantum resistant, a worrying question?
Our technology answers it.

Our technology consists in the amplification of True-random keys used by any One-time pad system (without being limited to this cryptography).

Planes filled with zeros and ones in the form of punched cards were historically sent for the exchange of keys between users of such a system, today replaced by diplomatic briefcases, as for the use of the famous WashingtonMoscow hotline or other intergovernmental lines secured point-to-point.

Thanks to our technology, a single physical exchange of 1 kilobyte of True-random binary data in the form of a QR code between interlocutors during their single meeting is enough to set up a secure exchange channel by One-time pad.

All subsequent keys will then be exchanged unconditionally safely across the network, without any further physical exchange.

Binary projections implemented as a dynamic-link library, materialised as the Projection.dll digital file, i.e., in other file formats required by the operating system.
This library can be used directly by the Ex0-True-Random-Pad-Sync tool, but is not limited to this use and can be used in any type of computer system requiring the use of one of the mathematical properties inherent in the function of decimal and binary projections (Established mathematical demonstrations and theorems).


What are the benefits and strengths of our technology ?

As shown in particular by the analyses based on Claude Shannon’s theory of information, the One-time pad system, recognised and used for more than a hundred years, is the only one to be considered unconditionally safe.

These analyses definitively consolidate the exclusive role of the encryption and decryption key of the One-time pad: the system is not concerned by the computing power of computers, nor of current supercomputers, nor of future quantum or post-post-quantum computers.


The One-time pad is not lacking in its cryptographic security operation, but its implementation may reveal historically exploited flaws.

A One-time pad system actually only operates a simple XOR operation between the binary input data to be protected and a totally random binary string of the  same size (True-random pads).

Thanks to its simplicity, this system is impregnable. It is also eminently faster than any other complex cryptographic algorithm, as no other system could be based on a single operation (the XOR operation in this case).

It is an ideal system for the security of connected devices in IoT infrastructures.


The One-time pad is a perfect security system. On the other hand, it is largely disadvantaged by the nature of its operation, because the length of the encoding and decoding keys has the same length as the data to be secured.

It is also and notoriously the least practical system to use in real conditions, thus depriving itself of a large-scale use. Up to this day!

  • Unconditionally secure data protection system.
  • Ideal for absolutely secure transmissions and communications.
  • Total independence of the opposing computing power, including quantum and post-quantum.
  • Extreme speed.
  • Ideal for IoT.
  • However, impossible to use easily under real conditions.
