Wireless networks have become one of the most extensively used communication systems in the world. Providing secure communication for wireless networks has become one of the main concerns. Wireless Local Area Networks (WLAN) is more and more popular; increasingly place of work buildings, airports, and other public places are being prepared with them. Quantum key distribution is a new method in key distribution system in quantum cryptography used to broadcast secret key between two legal parties. This method is a creation in quantum cryptography as part of quantum mechanics which solves the key distributions problem in cryptosystem by providing a secure communication channel between two parties with complete security guaranteed by the laws of physics.
