Quantum Key Distribution

Definition

Quantum Key Distribution (QKD) is a secure communication method that uses principles of quantum mechanics to generate and distribute cryptographic keys. It ensures that any attempt to eavesdrop on the key exchange will inevitably disturb the quantum state, thereby alerting the communicating parties to the presence of an intruder. This method provides an information-theoretically secure way to establish shared secret keys, which are essential for encrypting subsequent communications. QKD offers a robust defense against eavesdropping, particularly relevant for securing sensitive data and transactions in the digital asset space.
