Side Channel Attack on a Quantum Random Number Generator

The paper presents the results of applying an advanced attack on an external channel to an extractor of a quantum random number generator (QRNG). The attack is based on the verification of mathematical models of the interception channel and the EM signal of the extractor. Numerical simulation of the electromagnetic (EM) signal and the master key interception channel was performed based on the implementation of the DEMA algorithm of the attack on the AES-128 cipher. Measurements of the parameters of the EM signal and the interception channel were carried out on an experimental setup using a modern reference base in the field of electromagnetic compatibility.
