Quantum Key Distribution (QKD)
Quantum Key Distribution (QKD) is a quantum-safe solution that can be used to protect sensitive information against attacks by quantum computers. QKD is based on the principles of quantum mechanics and relies on the transmission of photons to establish a shared secret key between two parties.
In QKD, the two parties (usually referred to as Alice and Bob) share a secret key that is used to encrypt and decrypt messages. The secret key is generated by the exchange of quantum bits (qubits) through a transmission channel. The qubits are typically photons that are sent from Alice to Bob.
QKD relies on the principle of quantum entanglement, which ensures the security of the key exchange process. The entangled photons sent by Alice and Bob are correlated, and any attempt to measure the state of the photons will disrupt their entanglement. This means that any eavesdropper (usually referred to as Eve) attempting to intercept the transmission will inevitably introduce errors, which can be detected by Alice and Bob.
Once the shared key is established, Alice and Bob can use it to encrypt and decrypt messages securely. Any attempt by Eve to intercept the transmission will be detected, and the shared key will not be compromised.
QKD is considered a quantum-safe solution since it relies on the principles of quantum mechanics, which are not susceptible to attacks by quantum computers. However, QKD has its limitations and requires specialized equipment to implement, making it more expensive than conventional encryption techniques.
In summary, Quantum Key Distribution (QKD) is a quantum-safe solution that can be used to establish a shared secret key between two parties securely. QKD relies on the principles of quantum mechanics, which makes it secure against attacks by quantum computers. However, QKD requires specialized equipment to implement and has its limitations.
