Elementary quantum cryptography. For cryptographers who are not familiar with quantum mechanics. Arbekov I.M.

The book sets out the basic concepts and results that allow you to get an idea of ​​the tasks that arise when substantiating the secrecy of the cryptographic key distributed by the methods of quantum cryptography. On the example of the well-known VV84 protocol, the main stages of the quantum distribution of keys are described, including the transmission of quantum states, the procedure for correcting errors, the procedure for strengthening secrecy, evidence of the C-Secretary key relative to the attack of individual measurements, and the complexity of the complexity of the restoration of the quantum key that has the property of the S-secretism.

The materials presented are a teaching aid, intended for students, graduate students studying disciplines on cryptography, for those who want to take the first step in studying the problems of quantum cryptography. Understanding does not require deep knowledge of quantum theory, it is enough to prepare in the field of linear algebra, the theory of probability and the theory of information in the volume of the initial courses of higher educational institutions.
