Abstract
With the development of computer and communication technology, many people pay close attention to information security technology. Considering that the current encryption has many malpractices, some persons turn attention to quantum cryptography. Quantum Key Distribution is based on the principles of Heisenberg's uncertainty which guarantees that no eavesdropper can escape detection. According to this principle, this paper makes a study of the quantum cryptography technique, discusses the course of quantum key production and distribution in the quantum communication and the principle of quantum key distribution protocol in the communication by combining the application of quantum key protocol in the communication network. Current experimental progress on this aspect is introduced, existing problems are analyzed and some constructive suggestions are proposed. Finally, the developing trend for the theory of quantum password is prospected.
