SOLITON SIMULATION OF QUANTUM KEY DISTRIBUTION

Purpose is to assert that quantum entanglement is the main tool for communication and information processing. Methodology and Approach. Quantum key distribution protocols and problems of their protection were studied with the soliton model of entangled photons. They were evaluated hacking risks transmitting information between the legitimate users. The risks of hacking information transfer between legitimate users were assessed. There is also used a simple dichotomous signal generating method. This method can be the basis of probabilistic modeling of quantum states. Quantum Cryptographic Systems can be partially simulated on a classical computer with entangled soliton model, because quantum entanglement is the main tool for communication and information processing. Results. It is shown that the BB84 protocol is an unconditional security protocol using photon polarization between remote channels. Secret keys are used when transmitting information between spatially separated (remote) users. Theoretical and/or Practical implications. Using soliton modeling of quantum objects, it is possible to imitate their behavior and use some of their advantages on a classical computer. To a large extent, this can be done with the practical use of such a modeling method in the field of cryptography. A good imitation of quantum cryptographic processes by this method opens up prospects for the application of the soliton method for another use of quantum theory in practice.
