kvanttisalausteoria

Kvanttisalausteoria, or Quantum Cryptography Theory, is a field of study that explores the principles of cryptography derived from quantum mechanics. Unlike classical cryptography which relies on mathematical complexity, quantum cryptography leverages the fundamental laws of quantum physics to ensure secure communication. A core concept within this theory is the use of quantum phenomena such as superposition and entanglement to detect eavesdropping attempts. Any attempt by an unauthorized party to intercept or measure a quantum signal will inevitably disturb its quantum state, thereby alerting the legitimate users to the presence of an intruder.

One of the most prominent applications of kvanttisalausteoria is Quantum Key Distribution (QKD). QKD protocols, such as BB84, allow two parties to generate and share a secret cryptographic key with a provable level of security. The security of these protocols is guaranteed by the laws of physics, making them theoretically immune to computational attacks, even from future quantum computers that could break current encryption standards. Research in kvanttisalausteoria continues to focus on developing more robust and practical QKD systems, as well as exploring other quantum-based security primitives.
