| Open Access SQOUTProper Implementation of Quantum Communication Protocol and QBER Estimation
Proper implementation of quantum communication protocol and Quantum Bit Error Rate (QBER) estimation is crucial for ensuring the resilience of quantum communication systems against intercept-and-resend attacks, serving as the foundation for securing all forms of quantum communication.

List of techniques where this countermeasure can be applied.
Items: 3
| Description | Technique |
|---|---|
|
Monitoring the error rates in the quantum channel: An increase in error rates beyond a certain threshold indicates the presence of eavesdropping. |
Intercept-and-Resend Attack |
|
Against the mismatch in temporal DOF - monitoring of QBER and coincidence statistics [Makarov2008] |
Detector Efficiency Mismatch Attack |
|
Although the overall additional error rate from the attack may be low, one of the two bases will exhibit a significant error rate increase. This anomaly can trigger an error rate alert, serving as an effective countermeasure against the attack [Li2022]. |
Wavelength-Dependent Beamsplitter Attack |
