Аннотация:The detection of side radiation of transmitting devices is an additional source of information on distributedkeys. In contrast to the attack on a quantum communication channel, the detection of side radiation does notlead to perturbation of information states and errors on the receiving side. To ensure the cryptographic securityof quantum cryptography systems on the receiving side, it is fundamentally necessary to estimate theamount of information leakage through the side channel. A simple quantum derivation of amount of informationleakage through the side quantum channel with Gaussian noise has been reported. The proposedmethod is applicable not only to the channel with Gaussian noise but also to other types of side channels ofinformation leakage.
