Eavesdropping a QKD Network Using Quantum Unsharp Measurement Attacks
Date:
This lecture presents novel eavesdropping strategies against quantum key distribution networks using sequential unsharp measurements. We discuss how eavesdroppers can exploit measurement imprecision and quantum mechanics to extract secret information, and propose countermeasures.
Key Topics
- QKD security models and threat models
