Аннотация:In this paper, we consider the relationship between C Shannon’s unicity distance, which isdetermined by the number of symbols of the encrypted message required to uniquely find theencryption key of the cryptosystem in information-theoretical sense, ε-secrecy criterion inquantum cryptography and Holevo information. A lower bound for the unicity distance forε-secret keys in quantum cryptography is obtained. The relationship between unicity distance,ε-secrecy criterion in quantum cryptography and Holevo information is demonstrated.
