The device belongs to the latest generation of systems for protecting classified information with a high degree of reliability. The core of the development is based on the principle of quantum optics, which allows the secure transmission of encryption keys over fiber-optic networks. The optical random number generator operates on a non-deterministic physical process — polarization mode noise of a vertical cavity laser. The key feature of this device is its ability to reliably detect eavesdropping on the channel at the key generation stage. The random sequences generated by the device have successfully passed the specialized DIEHARD test and several other tests.
The project was developed by ITMO University in collaboration with the B.I. Stepanov Institute of Physics (National Academy of Sciences of Belarus) and Quantum Communications LLC.
