Passive Faraday Mirror Attack
The Passive Faraday Mirror Attack targets phase-encoded QKD systems by exploiting imperfections in Faraday mirrors (FMs), which fail to provide perfect polarization rotation. This vulnerability allows the threat actor (Eve) to partially discern the polarization state of the quantum signals, thereby gaining partial knowledge of the cryptographic key.
