Abstract:
Quantum key distribution (QKD) is one of the recent revolutions in cryptography field that was announced in first by Charles Bennett and Gilles Brassard in 1984. Here we create another QKD protocol that based on the three channel to communicate between two parties, and also ensures the connection is never established without providing the right identity in the first channel. Therefore, using the EPR pair in the first channel to approve the authentication in short time.
