Abstract:
This paper proposes a method for quickly generating a key sequence for use in the Vernam cipher using a quantum channel and an open communication channel. A sequence of independent identically distributed bits generated by a quantum random number generator is transmitted over an open communication channel, accessible to all users, and information about the method for selecting bits from this sequence is transmitted over the quantum channel. Estimates of the number of enemy attempts to brute force key sequences and the probability of these sequences matching between different users are given.
Keywords:quantum cryptography, information security,key distribution, quantum channel, quantum random number generator.
