Countermeasures

Temperature monitoring detects undesired variations in critical components like lasers and detectors.

This countermeasure incorporates several tactics to obscure the power consumption patterns that could otherwise be exploited to infer sensitive key information. These methods focus on altering the detectable computational behaviour without affecting the integrity or outcome of the reconciliation process. These methods, for example, include: Randomizing Power Consumption, Dynamic Voltage and Frequency Scaling, Randomization of Syndrome Computation Order, Insertion of Dummy Operations.

A Quantum Threat Intelligence Program equips organizations with the capability to generate and analyze threat intelligence specific to quantum systems. This program tracks trends and developments in quantum computing, communication, sensing and cybersecurity, helping to inform defensive strategies and mitigate risks associated with quantum technologies.

An example of such a solution is SQOUT by QuDef.

Tamper Protection involves implementing security measures to prevent "classical" unauthorized access and alterations to the physical hardware and related components.

End-to-End Encryption (E2EE) is a countermeasure for securing the classical communication channels within quantum communication systems, ensuring that all data transmitted between devices is encrypted and only accessible to the intended recipients.
