At Novosibirsk State Technical University, an innovative method was presented that ensures secure data transmission via fiber-optic communication lines. It is based on a laser generation mechanism that guarantees cryptographic protection at the physical level.
Scientists have developed a system that generates and distributes private cryptographic keys, as well as encryption protocols. An ultra-long fiber laser was used as the communication channel. This method allows users to exchange information without the risk of it being intercepted.
Our method allows data to be transmitted in a mode of indistinguishable values of bits "0" and "1" transmitted using identical laser pulses for an outside observer, specifically to confuse any illegitimate observer who would like to intercept and decode the data.
The Dean of the Faculty of Physics and Technology, Associate Professor of the Department of Laser Systems, Candidate of Physical and Mathematical Sciences Igor Korel believes that the developed technology has no analogues in the world. In his opinion, it can be useful in areas where a high level of information protection is required—for example, in the banking sector, for use by telecommunications companies, government and corporate information systems.
Earlier in Veliky Novgorod, a technical vision system was developed for unmanned tractors and dump trucks. It is designed to facilitate the navigation process. With its help, it is possible to build routes in the area of mineral development and detect obstacles. A prototype of the new system is already ready, and specialists have begun creating software.
