What is IDQKD?

IDQKD is an innovative method of QKD that separates security assurance from total dependence on device reliability. This approach aims to overcome the traditional assumptions that devices used in quantum communication are perfectly secure and trustworthy. By doing so, IDQKD addresses practical vulnerabilities in device implementations while maintaining the fundamental security guarantees provided by quantum mechanics.

Key Features of IDQKD:

1. Device Independence:

Unlike traditional QKD, IDQKD does not require devices to be fully characterized or trusted. Security is ensured even if the devices are imperfect or partially compromised.

2. Quantum Mechanics-Based Security:

The security of IDQKD relies on quantum phenomena such as the no-cloning theorem and quantum entanglement, ensuring that any attempt to intercept the key can be detected.

3. Robustness Against Side-Channel Attacks:

By not relying on device perfection, IDQKD mitigates the risks posed by side-channel attacks, which exploit imperfections in hardware or implementation.
