QKD System with Inevitable Alert for Detector-Control Attacks
Key Points
The alert detector consistently surpasses the eavesdropper’s sifted-key rate, improving quantum security.
When a detector-control attack is launched, the system maintains reliable performance with higher count rates.
This QKD system provides an added layer of defense against potential attack vectors in quantum communication.
Protecting the key exchange process is crucial in preventing unauthorized access to sensitive information.
Abstract
A quantum key distribution system is shown to produce counts rate on an alert detector that consistently surpasses the eavesdropper’s sifted-key rate when a detector-control attack is launched.
