kvantvõtme

kvantvõtme refers to a cryptographic key generated or distributed using principles of quantum mechanics. Unlike classical cryptographic keys which rely on mathematical complexity, quantum keys leverage quantum phenomena like superposition and entanglement to ensure security. The most prominent application of kvantvõtme is in quantum key distribution (QKD). QKD protocols, such as BB84 or E91, allow two parties to generate a shared secret key with a security guarantee based on the laws of physics. Any attempt by an eavesdropper to intercept the quantum signals carrying the key information will inevitably disturb their quantum state, alerting the legitimate users to the presence of surveillance. This inherent security feature makes QKD highly resistant to attacks from both current and future adversaries, including those who might possess powerful quantum computers capable of breaking many of today's classical encryption algorithms. The development and implementation of kvantvõtme are active areas of research and technological advancement, aiming to provide a robust and future-proof solution for secure communication.
