| Abstract: | Based on basic principles of quantum mechanics, quantum cryptography allows two remote parties to share unconditional security information. One of the core technologies is quantum key distribution（QKD）. 2014 is the 30 th anniversary of quantum cryptography. Since the first QKD protocol, BB84, was proposed in 30 years ago, quantum cryptography has been quickly developed in both theory and experiment, and some systems have been used in practical situations.In this paper, we review the history and current development of quantum cryptography, especially the quantum hacking and defense based on practical quantum cryptography systems. In the end, we discuss the future development of quantum cryptography. |
