Laser Damage Attack on a Simple Optical Attenuator Widely Used in Fiber-based QKD Systems

연구 분야: Cryptography

학회: 2022 International Conference Laser Optics (ICLO)

We present the results of an experimental study of laser damage attack (LDA) from the CW laser power up to 5.5 W at a wavelength of 1561 at a simple type of commercially available attenuator widely used in telecommunications and fiber-based QKD systems.
