Abstract

We propose a multiuser quantum key distribution system based on entanglement property which is simple, more efficient, cost effective and easy to implement in laboratory environment. Existing protocols uses base communication to provide security, as 50% of the time sender and receiver´s base is not agreed there are 50% bit loss during key distribution but our protocol does not need the base communication hence we achieve 3 dB performance improvement.
