Key Distribution

Key Distribution. Reference: Pfleeger, Charles P., Security in Computing, 2nd Edition, Prentice Hall, 1996. Symmetric Key Exchange Without Server. Assume that two users have a copy of a symmetric encryption key K. For a small number of messages, K may be used for encryption.

Quantum Key Distribution

Quantum Key Distribution. Yet another method of generating a key. Two major methods. BB84. E91. Device between Alice and Bob generates entangled photons. Alice and Bob read photons as orthogonal or diagonal. They compare notes on which they chose. Keep results from the same ones.

What is Quantum Key Distribution?

A unique property of quantum key distribution is the ability of two communicating users in order to detect the presence of third party willing to get knowledge of the key. It results from a fundamental aspect of quantum mechanics. For more details visit at - https://www.etsi.org/technologies/quantum-key-distribution
