How Quantum Cryptography Works
Principles of Quantum Mechanics
Quantum mechanics underpins the principles of quantum cryptography, particularly through phenomena such as superposition and entanglement. Superposition allows quantum bits, or qubits, to exist in multiple states simultaneously. This characteristic enhances the complexity of encryption. It’s fascinating technology.
Entanglement, on the other hand, creates a link between qubits, ensuring that the state of one qubit is dependent on the state of another, regardless of distance. This property enables secure key distribution. Any attempt to measure or intercept the qubits alters their state, alerting the communicating parties. This is a critical feature. Quantum mechanics revolutionizes data security.
Quantum Key Distribution (QKD)
Quantum key distribution (QKD) is a method that enables two parties to generate a shared, secret key using quantum mechanics. This process relies on the principles of superposition and entanglement to ensure that any eavesdropping attempts can be detected. The security of QKD is rooted in the fundamental laws of physics. This is a significant advantage.
During the key exchange, qubits are transmitted, and their states are measured. If an unauthorized party tries to intercept the qubits, the disturbance will alter their states, alerting the legitimate users. This feature is crucial for maintaining data integrity. Financial institutions can greatly benefit from QKD. It provides a robust framework for secure transactions.
