Underwater Wavelength Attack on Discrete Modulated Continuous-Variable Quantum Key Distribution [PDF]
EntropyThe wavelength attack utilizes the dependence of beam splitters (BSs) on wavelength to cause legitimate users Alice and Bob to underestimate their excess noise so that Eve can steal more secret keys without being detected. Recently, the wavelength attack
